19 Metal Convoluted Hose Testing and Cleaning Procedures Every corrugated hose assembly is leak tested prior to shipment. Standard testing consists of pressurizing the assembly with air and then submerging the entire assembly under water. This method is reliable and sufficient for the majority of applications. *Optional hose testing is available as noted below.

21 Optional Hose Accessories Spring Guard When there is potential for damaging an assembly in service, a guard can be easily installed during fabrication. This type of guard consists of a metal spring that is attached behind the fitting. The style of guard can be tailored to meet the application and the type of hose. Protective Cover If the potential for impact or high temperature damage is not severe, or if the additional weight and bulk of a full metal guard is unacceptable, rubber or plastic scuff guards can be installed to protect the corrugated hose and braid. Insulating Jackets If the corrugated hose is to convey hot media, and there is a potential for skin contact, an insulated, protective jacket is available. The jacket consists of a tubular banded fiberglass insulation, covered and impregnated with silicone rubber. The jacket is installed over the corrugated hose and metal banded in place. The jacket can also be used to insulate the corrugated assembly and either prevent ambient heat from being conveyed to the media or to reduce heat loss. Tagging A variety of tags and identifications can be affixed to hose assemblies. These include cardboard, plastic, and metal tags. Serial numbers, application information, assembly performance capabilities, and other customer specific information can be provided either on tags or permanently engraved onto one or both braid collars. Hose Testing Options Standard Leak Testing

22 Every corrugated hose assembly is leak tested prior to shipment. Standard testing consists of pressurizing the assembly with air and then submerging the entire assembly under water. This method is reliable and sufficient for the majority of applications. *Hydrostatic Testing While the standard test is designed to detect leaks, hydrostatic testing is designed to test the assembly's strength. Testing of an assembly to its full permissible test pressure can be economically and accurately accomplished by filling the assembly with liquid while concurrently evacuating all air. The assembly is then hydrostatically pressurized using high pressure pumps. The test pressure is maintained for a predetermined period of time. *High Pressure Gas Testing Testing with air under water, at pressures of up to 500 psi, is available for specialized applications. For a more sensitive test, the use of gases such as nitrogen or helium can be requested. *Helium Mass Spectrometer Testing This is the most sensitive leak detection method generally available. The standard test method is to attach the assembly to a mass spectrometer and generate a very high vacuum in the assembly. The exterior of the assembly is then flooded with helium. The relatively tiny helium atoms penetrate even very small openings and are drawn into the mass spectrometer where they are detected and the leak size quantified. Helium Mass Spectrometer testing can be modified to satisfy customer or regulatory agency requirements. Special Cleaning The hydroforming method of corrugated hose manufacturing inherently yields a very clean product. However, specialized cleaning for specific applications is available upon request for more information. MasterFit V-FLEX /4 I.D.-6 Hose I.D. Sizes All Metal Thin Wall Vacuum Tubing

Bend Radius, Static The smallest fixed radius at which a hose can be subjected. Braid A flexible wire sheath surrounding a metal hose that prevents the hose from elongation due to internal pressure. Braid is composed of a number of wires wrapped helically around the hose while at the same time going under and over each other in a basket weave fashion. Braid Angle The acute angle formed by the braid strands and the axis of the hose. Braid Make Up Term applies to description of braid, e.g , T3 SS, where: 3 is the number of carriers; is the number of wires on each carrier;.05 is the wire diameter in inches; and T3 SS is the material, Type 3 stainless steel. Braid Sleeve/Ring/Ferrule/Collar A ring made from tube or metal strip placed over the ends of a braided hose to contain the braid wires for attachment of fitting and ferrule, and to immobilize heat affected corrugations. Braid Wear Motion between the braid and corrugated hose which normally causes wear on the outside diameter of the corrugation and the inside diameter of the braid. Braided Braid

27 In this braid, the strands of wire on each carrier of the braiding machine are braided together, and then braided in normal fashion, hence the term braided braid. Brazing A process of joining metals using a non-ferrous filler metal having a melting point that is lower than the "parent metals" to be joined. Butt Weld A process in which the edges or ends of metal sections are butted together and joined by welding.

Mechanical Fitting/Reusable Fitting A fitting attached to a hose which can be disassembled and used again. Medium, Media The substance(s) being conveyed through a system. Misalignment A condition where two parts do not meet true. Nominal Diameter Indicates the approximate inside diameter. Offset-Lateral, Parallel

30 The distance that the ends of a hose assembly are displaced in relation to each other as a result of connecting two misaligned terminations in a system, or intermittent flexure required in a hose application. Operating Conditions The pressure, temperature, motion, and environment to which a hose assembly is subjected. Outside Diameter (O.D.) The external diameter of a metal hose, measured at the top of the corrugation or braiding. Penetration (Weld) The percentage of wall thickness of the two parts to be joined that is fused into the weld pool in making a joint. Pitch The distance between the two peaks of adjacent corrugations or convolutions. Ply, Plies The number of individual thicknesses of metal used in the construction of a wall of the convoluted hose. Pressure Usually expressed in pounds per square inch (psi). Pressure, Absolute (PSIA) A total pressure measurement system in which atmospheric pressure at sea level is added to the gauge pressure. Pressure, Atmospheric The pressure of the atmosphere at sea level which is 4.7 psi, or 9.9 inches of mercury. Pressure, Burst (Actual) Failure of the hose determined by the laboratory test in which the braid fails in tensile, or the hose ruptures, or both, due to the internal pressure applied. This test is usually conducted at room temperature with the assembly in a straight line, but for special applications, can be conducted at elevated temperatures and various configurations.

31 Pressure, Burst (Rated) A burst value which may be theoretical, or a percentage of the actual burst pressure developed by a laboratory test. It is expected that, infrequently, due to manufacturing limitations, an assembly may burst at this pressure, but would most often burst at a pressure greater than this. Pressure, Deformation The pressure at which the convolutions of a hose become permanently deformed. Pressure, Feet of Water or Head Often used to express system pressure in terms of water column height. A column of water foot high exerts a.434 psi pressure at its base.

Pressure, Maximum Test The maximum internal pressure which a hose can be subjected to without permanently deforming the corrugations. Pressure, Pulsating A rapid change in pressure above and below the normal base pressure, usually associated with reciprocating type pumps. This pulsating pressure can cause excessive wear between the braid and the tops of the hose convolutions. Pressure, Shock A sudden increase of pressure in a hydraulic or pneumatic system which produces a shock wave. This shock can cause severe permanent deformation of the hose corrugations, as well as rapid failure due to metal fatigue. Pressure, Static A non-changing, constant pressure.
