3 P T F E T H E O P T I M U M C H O I C E F O R H O S E L I N I N G S PTFE, or Polytetrafluoroethylene, comprises longchain molecules of carbon atoms, each linked to two fluorine atoms. The fluorine atoms provide a helical spiral which surrounds the carbon chain and protects it. It is this structure which creates the unique properties for which PTFE is well-known. EXCELLENT CHEMICAL RESISTANCE PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like fluorine gas at high temperature and pressure and liquid, boiling sodium metal. PTFE lined hoses can therefore be used for a wider variety of chemicals than any other hose type, making it the ideal choice for very corrosive chemical applications and multi-product applications. NON-STICK SURFACE The use of PTFE as a surface for cookware products has demonstrated to the world how easily cleanable PTFE surfaces are. This means that PTFE lined hoses can be purged 100% clean more quickly, easily and reliably than any other type of hose. EXCELLENT TEMPERATURE RANGE The cookware application also demonstrates another of PTFE s many attributes temperature resistance. PTFE itself can be used as a hose liner at temperatures from -150 C up to +260 C, dependent upon the hose design and the application conditions. This is the widest temperature range of any rubber or plastic hose lining material. HOSE DESIGN The only issue with PTFE as a hose lining material is the best way it can be integrated in to the hose design. This is where Aflex Hose have a proven record of success over the last 30 years. Section from a PTFE Molecule, 16 Angstrom Units long Fluorine Atom Carbon Atom 03

4 C O R R O L I N E H O S E D E S C R I P T I O N INTRODUCTION Corroline hose was designed and developed to provide customers with a universal chemical hose product which combined all the requirements they had requested for chemical plant applications, particularly the need for improved flexibility. Corroline hose not only supersedes but also improves upon the wide variety of alternative Chemical Hose products currently available. CONSTRUCTION Corroline is built around a patented PTFE hose liner design, which has a slightly rippled smooth bore inside, but convoluted outside to generate excellent flexibility combined with hoop strength. A stainless helical wire is wound in to the external convolutions, which adds to the kink resistance, crush resistance and the resistance of the hose to both pressure and vacuum. This reinforced PTFE Liner construction is strong enough to withstand full vacuum and kinking without the need for either internal convolutions or the need to bond the liner to an outer cover, making it an ideal hose liner design, and a significant improvement upon standard products currently available. The PTFE liner is then further reinforced with an outer braid, either a Stainless Steel wire braid (SS Grade) or a Polypropylene braid (PB Grade) to provide two braided hose grades. The most popular grade (RC Grade) includes an outer cover of abrasion resistant, black antistatic EPDM rubber which is extruded on to a SS braided liner, with a super-smooth surface finish to aid external cleaning. A yellow, CORROLINE stripe is printed on to the cover. Other texts and coloured stripes are also available to special order.

MATERIALS & SPECIFICATIONS Corroline GP is a virgin PTFE liner, manufactured from hose grade PTFE which conforms to the requirements of: FDA 21 CFR The helical reinforcement is High Tensile Grade 304L SS wire. GP & AS GRADE APPROVALS The full list of approvals and certifications are given on page 27. Both Grades have also been tested for Leachables and Extractables in accordance with BPSA recommendations, with satisfactory results. Copies of the Report are available from Aflex Hose. PURPOSE Corroline AS is an essential requirement in applications where there is the risk of an electrostatic charge build-up on the inside surface of the PTFE tube which may then discharge through the tube wall. Media passing through which create such a risk are fluids which have a Conductance of less than 10-8 S/m (Siemens per Metre), or 10 4 ps/m such as fuels, solvents, freons, some WFI (ultra-pure Water for Injection ) and non-polar organics which are being transferred at a medium to high flow velocity. All twin or multi phase media, and any non-mixing media, such as powder in air, or water droplets in steam, in gases or in oil, also colloidal fluids constitute a particular hazard for static charge generation, and always require grade AS. If in doubt, consult Aflex Hose. MATERIALS & SPECIFICATIONS Corroline AS is an anti-static PTFE liner manufactured from FDA approved PTFE, and less than 2.5% of high purity Carbon Black material to FDA requirement 21 CFR and European Commission Directive 2007/19/EC. The carbon is encapsulated by the PTFE, and in normal, non-abrasive applications will not come loose to contaminate any fluid passing through. This has been proved during Leachables and Extractables testing. SPECIFICATIONS When AS (Antistatic) grade hose is specified, then the hose supplied will be in accordance with the requirements of BS5958 Part 2, 1991 Clause 19.3, when tested in accordance with EN ISO 8031 Clause 3.1, which requires that the resistance between a plug inserted 25mm into the bore at the end of the hose assembly, and one of the metallic end fittings should be less than 10 8 ohms. NOTE: When in service, at least one end fitting must be connected to earth, to permit dissipation of the static charge from the end fitting. 10

High tensile AISI 304L stainless steel wire is used, to give maximum pressure resistance and external protection to the hose. P B - P O L Y P R O P Y L E N E B R A I D PURPOSE RC Grade hose is the general purpose product, used in a wide variety of applications. A Black, Antistatic EPDM rubber to extruded over the SS braided product, to protect the SS braid with a tough, abrasion resistant rubber cover. The rubber cover hose has a smooth finish, to make it easy to wipe clean. A yellow CORROLINE stripe is printed on to the cover. Other texts and coloured stripes are available to special order. * S P E C I A L N O T E * PURPOSE Polypropylene braided hose is often preferred to SS in applications involving frequent handling and movement of the hose. PB braid is lighter in weight, and any broken strands will not cut the operator s hands. In addition, PB braid is not prone to chloride stress corrosion, and has generally good chemical resistance. To ensure *Electrical Continuity between end fittings, 2 strands of Monel wire earthing strips are criss-crossed on to the liner, underneath the Polypropylene Braid. These are folded back underneath the ferrule at both end fittings, to make an electrical contact. NOTE: Prolonged exposure to sunlight eventually results in UV degradation of PB braid. * ELECTRICAL CONTINUITY Electrical continuity requires that the hose assembly supplied is electrically continuous, or conductive, between metal end fittings at each end of the hose. This can apply whether the hose is GP or AS grade. The requirements for electrical continuity are specified in the German Document BRG132, and the Specification EN ISO 12115, tested to EN ISO 8031 Clause 3.7, which requires that for hose assemblies with a resistance between fittings of <10 2 ohms, a letter M can be applied, or <10 6 ohms, a letter Ω can be applied. Corroline Hose Assemblies are all electrically continuous with a resistance of <20 ohms, and therefore meet the requirements of both M and Ω, but are not stamped unless requested. 11

24 C O R R O L I N E D I P P I P E S F I X E D D I P P I P E S Description Fixed Dip Pipes are fairly rigid, thick wall PTFE tubes, either straight or 90 elbowed, which are directly crimped to the end of Corroline hoses. They are designed for insertion into drums, tanks and reaction vessels in order to suction drain (or inject) process fluids transferred through the hose. Materials Standard dip pipes are in anti-static (AS) PTFE. How to order Specify the size and material of the dip pipe, whether it is straight or 90 elbowed. Give the length of the find leg of the dip pipe and the length of the rest of the hose assembly separately. Maximum Working Pressures Dip Pipes are normally only tested to 4 Bar Pressure, and are not suitable for use at pressures higher than 3 Bar. They are usable at negative pressure up to full vacuum. If higher pressure ratings are required, consult Aflex Hose. Lengths Dip Pipes are supplied as standard in 1 metre lengths, but can be supplied in any length to individual requirements.

Working Pressure - Unique Serial Number - Month & Year of Manufacture - Aflex Hose Telephone Number - CE Mark (if applicable) S T A N D A R D L A B E L L I N G This information is normally vibro-etched on to a loose stainless steel Ring mounted on the hose. In some cases, at the discretion of Aflex Hose, the information may be etched on to a thin stainless steel plate which is clamped to the hose, or on to the end fitting ferrule at one end. This may be necessary for example, if the customer requires additional information which may not fit on to a Ring. Customers may specify which labelling system they require, and may request additional information on the label. P U R E T A G L A B E L L I N G A N D C O L O U R C O D I N G Puretag Labelling and Colour Coding (Patent Pending) A label and/or Colour Code is encapsulated on to the braid by a transparent rubber cover which is integrally vulcanised and fully bonded to the rubber cover on the hose. Another alternative is an RFID programmable tag, encapsulated in the Rubber (Aflex Hose Flowtag system) - consult Aflex Hose for details. Further information is available on the Puretag product information document on the website. Colour Coding A coloured PTFE spiral strip is wound on to the hose. It can be left loose, or it can be encapsulated under a transparent, heat-shrunk polyolefin sleeve. 25

26 C O R R O L I N E H O S E : S P E C I A L U S A G E C O N D I T I O N S Cleaning & Sterilising Systems - CIP, SIP and Autoclave CIP & SIP The primary consideration is whether the cleaning and purging cycle is likely to develop an electrostatic charge on the internal surface of the liner, in which case AS is required. AS hose and Static charge generating systems are fully described on page 10. CIP systems using high electrical resistivity solvents like Toluene will require AS hose. Another problem arises when the cleaning fluids or WFI or steam are purged out of the line using nitrogen, compressed air or another gas, because droplets of liquids or water in the gas then generate a multi-phase condition until they are cleared out, which will generate a static charge, and so will require AS hose. In applications where an AS hose is not acceptable (in spite of the full approvals ratings, see page 27) it will be necessary to consult with Aflex Hose for a solution. Autoclave Autoclave sterilisation does not normally involve any high flow rates through the hose bore, so static is not a problem. Bioflex grades GP and AS, with SS or HB braids can be autoclaved an indefinite number of times throughout their normal service life. The rubber covered grades, RC and SI, are also able to withstand many autoclave cycles at normal autoclave temperatures (121ºC, 250ºF), although eventually the rubber may discolour and/or degrade. Consult Aflex Hose for more specific information. PTFE Hose - Use with Halogens PTFE hose liners can react chemically with Fluorine, Chlorine Trifluoride and Molten Sodium Metal, and so must not be used with these chemicals. When PTFE lined hose is used with the halogens Chlorine and Bromine, or any corrosive halogen compounds which diffuse easily and are gaseous for example HF or HCL gas, or phosgene, then trace quantities may diffuse through the PTFE liner to the outside. Only trace quantities are required, mixed with atmospheric moisture, to create a serious corrosion condition with stainless steel wire braid in particular. If these conditions apply, consult Aflex Hose for a more suitable alternative hose product. Penetrating Fluids and Gases Like other plastics and rubbers, in certain special circumstances PTFE is sometimes subject to diffusion through the tube wall, dependant upon the nature of the chemical, and the pressure and temperature of operation. As mentioned above, Gaseous Halogens represent a specific problem. Automotive fuels, on the other hand, diffuse much less through PTFE than through other rubbers and plastics. Some other types of penetrating fluids can also diffuse through PTFE to varying degrees, which may or may not present a problem. Known examples are sulphur trioxide, glacial acetic acid and methyl methacrylate. Consult with Aflex Hose if these, or any other gases or fluids which are known to be penetrating are to be used. Gas/Fluid Cycling There are some applications where the fluid passing through the hose turns into a gas, then back into a fluid, then into a gas etc., in a cyclic sequence. This is normally associated with changes in temperature and/or pressure. For complex reasons these conditions are extremely damaging to the hose liner, whatever material it is made from. For example, hoses are sometimes used to pass steam, water, steam etc into rubber moulding presses, in order to heat the mould, then rapidly cool it before reheating in the next cycle. Hoses of all types fail rapidly in such an application, and PTFE lined hose is no exception. Consult Aflex Hose for further information if these conditions apply. Connecting Assemblies for use in Applications The lengths of hose assemblies, and their configuration and use when connected into the application must always be in accordance with the Hose Configuration information at the end of this literature. When being connected for use in applications, the end fittings on hose assemblies must be connected to correct mating parts in the correct way, using the correct tools - spanners, clamps, nuts and bolts etc. The connections must be sufficiently tightened to ensure that the joint is leak-free, but must not be over-tightened as this can damage the sealing surfaces, especially with PTFE lined and flared end fittings. In applications involving the transfer through the hose of expensive or dangerous fluids or gases, the connections must be pressure tested first before being put in to service. This should be done with some harmless media, like water or compressed air, to 1 1 /2 times the maximum working pressure of the hose assembly, as defined in this brochure. If in doubt, consult Aflex Hose for advice. Special Applications Aflex Hose PTFE lined hose products are not acceptable for use in the following, special applications: - Radioactive Applications involving high energy radiation, including Gamma radiation (degrades PTFE). - Medical Implantation Applications (Not tested for use). - Aerospace Applications (exclusive contract applies). - Applications on all types of USA Military Equipment, including tanks, vehicles, weapons, FCS equipment and all others (exclusive contract applies). 26

28 H O S E C O N F I G U R A T I O N & L E N G T H C A L C U L A T I O N S - f o r B E N D R A D I U S Hose Configuration Requirements Hose Assemblies are usually connected at both ends in service. They may then either remain in a fixed, or static configuration or in a flexing, or dynamic configuration. Whether static or dynamic, the First Rule concerning the configuration of the hose is that the bend radius of the hose must never be less than the Minimum Bend Radius (MBR) for the hose as listed in the relevant hose brochure. The most common situation when this is likely to occur is when the hose is flexed at the end fitting, with stress being applied to the hose at an angle to the axis of the end fitting. Typically, this happens either because the length of the hose is too short, or because the weight of the hose plus contents creates a stress at an angle to the end fitting. The Second Rule, therefore, if possible, is to design the configuration to ensure that any flexing in the hose takes place away from the end fittings. ( Dynamic) Configuration INCORRECT - Hose too short Less than MBR ( Static) Configuration INCORRECT - Weight of hose is at 90 to Axis of End Fittings Less than MBR CORRECT - No flex at end fittings CORRECT - No flex at end fittings OR 90 Elbow end fittings 28

29 H O S E C O N F I G U R A T I O N & L E N G T H C A L C U L A T I O N S - A B R A S I O N & T O R Q U E The Third Rule is that the hose configuration should always be designed, and supported where necessary, to avoid any possibility of external abrasion. In some cases, the length, configuration and angle of the hose can be designed to avoid abrasion. In others, static or moving support frames or support wheels are required. Abrasion Incorrect - Hose abrasion against hose) Incorrect - Abrasion inside support Correct - No hose abrasion Correct - No abrasion over support The Fourth Rule is that the hose must not be subjected to torque, either during connection, or as a result of the flexing cycle. Torque (twist) in the hose can be applied during connection if the hose is accidentally twisted, or if the second end being connected is a screwed connection, and the hose is subjected to torque during final tightening. In a flexing application, if any flexing cycle of the hose occurs in 3 dimensions instead of 2, then torque will also occur: CORRECT - Flexing movement takes place in 2 dimensions INCORRECT - Flexing movement takes place in 3 dimensions, so torque is applied Both Corroflon and Corroline hose have good resistance to a small level of torque, much better resistance that rubber or SS hose types, but it is still the best practice to take whatever steps are necessary to eliminate torque. If in doubt, consult Aflex Hose. 29

30 H O S E C O N F I G U R A T I O N & L E N G T H C A L C U L A T I O N S - f o r L E N G T H C A L C U L A T I O N S Calculating The Hose Length The formula for calculating the bent section of the hose length around a radius is derived from the basic formula that the circumference of a circle = 2πR, where R = the radius of the circle, and π = a constant, = So, if the hose goes around a 90 bend, which is 1 /4 of a full circumference, and the radius of the bend is R, then the length of the hose around the bend is = 1 /4 x 2πR. Or half way round, in a U-shape, = 1 /2 x 2πR. Note : In calculating the length of a hose assembly, the (non-flexible) length of the end fittings must be added in, also the length of any straight sections of hose, as in the following example: Example : R L = 1 /4 x 2πR To calculate the length for a 2 bore size hose with flange end fittings, to be fitted in a 90 configuration with one leg 400mm long, the other 600mm long. Length of Bent Section (yellow)= 1 /4 x 2πR (334) = 1 /4 x 2 x x 334= 525mm Length of top, Straight Section, including the top end fitting length R L = 1 /2 x 2πR = = 266mm Length of bottom end fitting = 66mm Total length of Hose Assembly = = 857mm Things to consider (a) A hose will normally take the longest radius available to it to go around a corner, not the MBR! Also - always remember to include the non-flexible end fitting lengths. (b) In dynamic applications, remember to always calculate the 600mm lengths for the most extended configuration during the flexing cycle, not the least extended = 266mm 334mm (c) If the configuration is simply too complex for calculation, then obtain a length of flexible tubing of some kind, mark on paper, or a wall, or floor, or both where the connection points will be relative to each other, scaled down if necessary, then manually run the flexible tubing between them with full radii round bends. Measure the extended length, then scale R = mm 400mm up if necessary to determine the approximate length of the hose. RADIUS R = = 334 If in doubt, consult Aflex Hose. End Fitting Length = 66mm 30

31 C O N D I T I O N S O F S A L E General Aflex PTFE hose products have not been designed or tested to be suitable for use in any Aerospace, Medical Implantation or Radioactive applications, nor is it suitable for use in any USA military vehicles, weapons or equipment and such use is therefore strictly prohibited unless written approval from Aflex Hose Ltd has been given. Aflex Hose Ltd will not accept liability for any failures of the Aflex Hose Products which are caused by customers failing to perform their Responsibilities as specified in these Conditions of Sale. It is the customer s strict Responsibility to review all of the usage limitations given for the hose which he intends to use in an application, to ensure that the application conditions are in compliance with those usage limitations. The usage limitations are specified both on this page, and throughout the relevant sections under Products and Information on the Aflex Hose website. Customers must always consult the latest, up to date information, which is available and downloadable from the Aflex website, or request from Aflex Hose Ltd. It must be accepted, however, that the usage limitations specified elsewhere in the Hose Product Information and on this page are intended as a guide only, since every possible factor in every type of application cannot possibly be covered. It is therefore the Customer s Responsibility to ensure the design suitability and safety of the products in their intended applications, giving particular consideration to the chemical and electrostatic compatibility of the fluids or gases passing through, the possibility of diffusion of fluid or gases through the PTFE hose lining, the possibility of external corrosive conditions, the types and likelihood of excessive mechanical abuse, such as abrasion (internal or external), crushing, excessive flexing or vibrations etc, and any excessive temperature and/or pressure pulsing conditions, all of which may cause premature hose failure. It is also the Customer s Responsibility to consider, and take account of the degree of risk involved in any hose failure, including the provision of adequate protection in the event of any risk to employees or the general public. In applications where any type of hose failure would lead to financial losses if the hose is not replaced immediately, it is the Customer s Responsibility to order and hold in stock spare hose(s) accordingly. It is also the Customer s Responsibility to advise Aflex Hose in writing if there are any special requirements for the hose, including cleaning, or drying, or extra testing requirements which are in addition to normal industrial standards. If the Customer has any doubts concerning these or any other usage limitation or safety parameters, it is the Customer s Responsibility to consult Aflex Hose Ltd, to request a written response to any queries. It is the Responsibility of the Customer to ensure that if the product is sold on, or passed on, however many times, that all the necessary information including this page and the Aflex Hose website address are also passed on to the final user, together with a specific requirement that the final user must review the usage limitations in terms of his own application. Hose Service Life It is not possible to guarantee a minimum service life for any of the Aflex Hose products which can be applicable for every type of application. (For example, PTFE lined hose has been used in one application where it was cycled with hot steam, then cold water, also flexed every 17 seconds 24 hours per day, and the customer was very satisfied with a service life of 3 weeks before failure. In other light duty applications carrying pharmaceutical products, however, many Corroflon hoses are still performing satisfactorily after 20 years in service). Service life predictions or guarantees can only be given in cases where all the relevant information concerning the application is given in writing to Aflex Hose, and Aflex Hose subsequently replies in writing prior to the order being placed. If such a written undertaking is not sought and given, then Aflex Hose cannot be held liable for any hose product failure which the customer considers to be premature, excepting failures which are due to faulty materials or manufacturing defects. 24 Month Warranty Aflex Hose Ltd warrants its products to be free from faulty materials or manufacturing defects from the date of the initial sale, for 24 months. Product Failure In the event of a product failure, Aflex Hose requests that the product should not be cut up or tampered with, but should be de-contaminated and returned to Aflex Hose, plus a decontamination certificate, for examination and analysis of the fault. The customer should also provide full details in writing of the application conditions under which the hose failed, including Pressure, Vacuum, Temperature, Flexing and any cycling of any of these, also the fluid and gases passing through the hose, and the total time that the hose has been in service. The customer may send his own witness to the examination if required. Aflex Hose will provide a full Non Conformance Report for the customer. If faulty materials or a manufacturing defect in the hose was responsible for the failure to perform then, the maximum liability to be accepted by Aflex Hose would include the invoice value of the failed hose itself, or the invoice value of the whole customer order if appropriate, also any reasonable costs for removal and replacement of the hose, and costs for packing and despatching the failed hose back to Aflex Hose. Aflex Hose Ltd will not accept liability for any other consequential or financial losses, including, but not limited to loss of profits, loss of products or downtime costs. Untested Hose for Self Assembly by Customers Aflex Hose sometimes supplies loose hose, without end fittings attached to Self Assembly Customers, who will then cut the hose to length and attach end fittings to make up Hose Assemblies. Self Assembly Customers must then accept the responsibility to carry out pressure testing of 100% of such assemblies to 1 1 /2 times the Maximum Working Pressure before supply for end use, to validate both the hose and the end fitting attachment. When pressure testing hoses with a plastic or rubber outer cover, the cover will mask any signs of leakage for a time. It is therefore recommended that pressure testing with air under water for a minimum test period of 5 minutes should be applied to covered hoses. Unless the customer requests, and Aflex Hose confirm that their loose hose is pressure tested before supply, such testing is not normally applied by Aflex Hose, because this testing requirement is satisfied by the Self Assembly Customer during his own testing of the finished Hose Assembly. The Self Assembly Customer must also accept responsibility for determining and approving the Design Suitability of the hose assemblies for their intended use before supply. This includes determining and requesting or applying any special tests which may be identified as necessary to ensure suitability for the intended use. Aflex Hose will only accept liability for its hose products which are assembled by customers themselves if all the hose and fitting components were either supplied by Aflex Hose or manufactured in accordance with Aflex Hose drawings, and they were assembled and tested in accordance with Aflex Hose s current Manufacturing and Testing Instructions. Untested Hose Assemblies Aflex Hose is sometimes requested by customers to attach non-standard end fittings to hose assemblies which they supply, and in some cases it is not possible to connect these fittings to the pressure test system. In such cases a Concession not to test is obtained from the Customer, and a label is attached to the hose assembly, warning that it requires pressure testing before use. Force Majeure Aflex Hose Ltd shall not be liable for any delay or default in performing in accordance with any Customers order if the delay or default is caused by conditions beyond its control, including, but not limited to wars, insurrections, strikes, natural disasters or performance failures by Carriers, sub-contractors or other third parties outside the control of Aflex Hose Ltd. Legal System These Conditions of Sale are subject to English Law. 31
