3 DIMENSIONAL RANGE / OPTIONS AND PARAMETERS Straight hoses diameter range: ø 50 ø 2200 mm. (ø2 87 ). Preformed elbow diameter range: ø150 ø 1000 mm. (ø6 40 ). Straight hose length limits: mm (40 ) mm (38.7 ) is our standard length. For shipment of a 40 hose you will need a 45 container, for shipment of our standard length you will need a 40 container. 3(47)

4 PRESSURE RATINGS The Maximum Pressure Rating is dependent on the inner diameter (ID) of the hose. Trelleborg manufactures a big range of diameters in combination with different pressure ratings. Up to 650 psi (48 bar) design pressure for a 30 hose is possible. Design Conditions 1. Design pressure: slurry line design pressure. 2. Burst pressure: 3 slurry line design pressure. 3. Design for partial vacuum, 80 kpa absolute pressure (21 kpa vacuum). 4. Design Temperature: 95 C. 5. Ambient Temperature Range: -50 C to 40 C. 6. Liner and/or cover thickness is not considered in design calculations for pressure containment. 7. Hose accommodates expansion under pressure with both ends fixed. Internal pressure may cause expansion of rubber hoses in both axial and circumferential ways and too much axial movement can cause buckling with fixed ends. The hoses are designed so that buckling is prevented during the operation. If the service stream requires higher vacuum rating than partial vacuum this must be clearly mentioned in the purchase description. The rubber hose will be designed and constructed suitably for this application, without causing collapse or buckling of the rubber hose under the specified vacuum conditions. 4(47)

5 CONSTRUCTION Wear liner: Reinforcement: 1785 Trelleborg Oil Sands Compound (NR/NBR/BR) Thicknesses of up to 100 mm (4 ). The design requirements determines the liner thickness. Liner is manufactured from a hydrocarbon resistant elastomer that maintains the required physical properties throughout the design temperature range. Liner has good resistance to cutting and wear by solid particles in the slurry. Liner is thick enough to provide the required wear performance with a nominal thickness of 50 mm (2 ) being considered standard for hydro-transport and coarse tailings. For the applications having mild wear issues (i.e., middlings, fine tailings) or requiring more flexibility of rubber hoses, thinner liner will be used with a nominal thickness of 12.7 mm (0.5 ) being considered as minimum. Liner shows no evidence of blisters or delamination in oil sands applications. Liner has smooth bore surface: surface irregularities may cause slurry turbulence and the resultant accelerated wear. Polyester-, Aramide- and Rayon cord are options for reinforcement materials. Reinforcement material and thickness depending on the pressure rating and application and will be determined by Trelleborg A unique feature is that the reinforcement cord layers are rubberized to prevent inter cord rubbing and wear. Most of the cord layers are rubberized in house. Outer cover: 1192 Trelleborg Oil Sands Compound (EPDM/NR) Thickness standard mm for oil sands applications. Cover has good resistance to weathering, sunlight, abrasion, bitumen, and mechanical damage common to outdoor pipeline service. Cover is thick enough to provide the required protection of the reinforcement from mechanical damage. 5(47)

6 FLANGE OPTIONS Built-in Rubber Flange Built-in Nipple Flange Victaulic BIRF BIN VIC BIRF Built-in Rubber Flange Double Action flange in two designs The Double Action flange is Trelleborg s most recent development. The main feature of this flange is the superior axial strength due to integrated locking flange. This flange is able to accept high bending loads due to thick integrated flange and backing flange and will not fall apart due to rust. Thick integrated flange and backing flange allow for a large radius in flange neck which eliminates cutting forces on the cords. The Double Action flange comes in two designs: the Double Action flange and the Double Action flange XA (Extreme Application) with steel gasket flange. The latter gives even better sealing at high pressures and offers protection to the reinforcement cords when mounted to sharp edged raised face flanges. We recommend this flange for applications where a very short hose is needed with a relative big angle of curvature and high working pressure. The bold circle diameter must be big enough to accommodate the cord layers and rubber. This will be determined by Trelleborg with the proposed design. Double Action flange Double Action flange XA Flange material: A 105 (N) or per end user s requirement Design Code: ASME B31.3 ASME B16.47 and B16.5 Tolerances 6(47)

7 BIN Built-in Nipple Flange Steel couplings vulcanized in for extreme working conditions Our solid steel couplings are suitable for heavy and very heavy duty applications. They can be made with the smallest possible pitch circle diameters and are vulcanised into the hose. These couplings are secured with our safety strap system for extra safety. This system makes the hose suitable for high loads and bending moments and prevents the hose / nipple connection to fail under extreme circumstances. Flange material: A 105 (N) or per end user s requirements Pipe material: API 5L Grade B or per end user s requirements Design Code: ASME B31.3 ASME B16.47 and B16.5 Tolerances VIC Victaulic coupling Flange material: Pipe material: A 105 (N) or per end user s requirements API 5L Grade B or per end user s requirements 7(47)

8 SAFETY FACTORS Standard for oil sands application the safety factor is 3 times the design pressure. Depending on the risk of the area. In most of the Trelleborg hoses and rubber applications you can choose for conductivity wires in the hose at certain levels for extra safety. Trelleborg recommends: Wear Indicating Wire System Hoses can be equipped with a wear indicating system consisting of a wire conductor embedded in the liner at specific depths. In case of single wire system, the wire conductor is embedded at a nominal depth of 75% wear life (at the depth corresponding to 75% of total liner thickness from the internal surface). In case of double wire system, the wire conductor is embedded at a nominal depth of 50% and 75% wear life. A wear indicator check point is provided to perform scheduled continuity tests. The wear indicator check point is designed not to be vulnerable to the mechanical or environmental (e.g., water) damage during installation, handling and pipe rotation. The above requirements will be waived if the liner thickness is 12.7 mm (0.5 ) or less. 8(47)

9 QUALITY ASSURANCE QUALITY ASSURANCE, INSPECTION AND TESTING Trelleborg maintains traceable quality assurance records on each rubber product throughout the manufacturing process, from raw material, inspection and testing, hose assembly, to final testing and inspection. Responsibility The responsibility to properly manufacture and inspect material or equipment prior to its delivery rests solely with Trelleborg The fact that material or equipment has been inspected by the end user does not relieve Trelleborg of the responsibility to meet all requirements specified. Definitions Verification Point A step in manufacturing where verification must confirm compliance with quality requirements. Trelleborg will advise the end user when these points are reached, a reasonable time in advance as shown on ITP. Trelleborg may proceed past a Verification Point providing permission to proceed is obtained from the end user. Hold Point A step in manufacturing where witnessing by end user is mandatory. Fabrication or testing must not proceed past a hold point without end users approval. Trelleborg will advise the end user of reaching this point a sufficient time in advance as provided in the ITP. Trelleborg is responsible for the development of the ITP. The ITP lists the minimum hold points required, and types of tests that require witnessing or verification by end user. Trelleborg shall consult the end users QA/QC to discuss these requirements prior to developing the plan. The end users QA/QC must review and accept Trelleborg s ITP prior to the start of production. Trelleborg can provide the end user unprized copies of our purchase orders for plates, forgings, pressure containing parts and fabricated sub-assemblies if needed. Trelleborg QC Manual and procedures are available for review and approval. Trelleborg can provide records of all personnel qualified in welding and NDE if needed. Trelleborg can provide mill test certificates for all pipes and flanges if needed. 9(47)

10 INSPECTION AND TESTING (HYDROSTATIC TEST) TRELLEBORG RUBBER HOSE TEST PROCEDURE TABLE OF CONTENTS 1.0 FOREWORD 2.0 ISO 1402: GENERAL 4.0 DEVICE AND MEASUREMENT INSTRUMENTS 5.0 HOSE TESTING 6.0 APPLICATION OF HYDROSTATIC PRESSURE 7.0 HYDROSTATIC PRESSURE TESTS 8.0 TEST REPORT 10(47)

11 1. Foreword The International Standard ISO 1402:1994 was used as referenced document for this test procedure. 2. ISO 1402 :1994 Rubber and plastics hoses and hose assemblies Hydrostatic testing This International Standard specifies methods for the hydrostatic testing of rubber and plastics hoses and hose assemblies, including methods for the determination of dimensional stability. 3 General Unless otherwise specified, all tests shall be carried out at ambient temperature. The defined and accepted drawing of the product will always be leading. 11(47)

12 4 Device and measuring instruments 4.1 A water pressure device, capable of applying pressure at rate specified, up to the required test pressure. 4.2 Calibrated pressure gauge and pressure transmitter with digital readout are chosen for each test so that the test pressure is between 15 % and 85 % of the full-scale reading. 4.3 In the interest of accuracy, calibrated pressure gauges or pressure transmitters with digital readouts are checked at frequent intervals (minimum once a year). 4.4 The water hose inlet and the hose pressure measure connection mounted on the hose blind flanges are separated as far as possible to minimize shock damage from pump pulsations and to measure only static pressure without influence of the dynamic pressure (Fig. 1). 1/2" HOSE 3/4" 3/4" 1/2" PUMPUNIT 3/4" PRESSURE MEASURE UNIT Fig Calibrated sliding vernier calipers or micrometers, and measuring tapes are used for measurements. 12(47)

13 5 Hose Testing 5.1 Straight hose The hydrostatic pressure tests and burst tests shall be carried out on a hose with blind flanges and with the hose ends unrestricted. 5.2 Rubber bends and elbows The hydrostatic pressure tests and burst tests shall be carried out on a bend or elbow mounted in a test framework with fixed length and dimensions including blind flanges. 5.3 Inter stage offset spool The hydrostatic pressure tests and burst tests shall be carried out on an inter stage spool mounted in a test framework with fixed length and dimensions including blind flanges. 6 Application of hydrostatic pressure 6.1 General Potable water shall be used as the test medium. WARNING A pressurized hose can fail in a potentially dangerous manner and for this reason, the test must be performed in a protected and safe area. 6.2 Procedure Mount special test blind flanges on the hose to plug the ends. Mount when applicable on the test framework Fill the hose with potable water, expelling all air, and connect to the test equipment. Open the valve and apply the hydrostatic pressure at a uniform rate of increase. (6.2.3) Measure the pressure using a calibrated pressure gauge and with digital readout The rate of pressure increase and measurement intervals shall be constant and chosen to reach the final pressure and shall be decided between the manufacturer and end-user. 13(47)

14 7 Hydrostatic pressure tests 7.1 Proof pressure hold test When proof pressure tests are used to determine leakage of hoses, apply the specified proof pressure in accordance with and hold it for not less than 10 minutes or more, unless otherwise specified in the drawing of Trelleborg. Examining the test hose during this period for evidence of leakage, cracking, abrupt distortions indicating irregularity in material or manufacture, or other signs of failure. Unless otherwise specified for the hose, the proof pressure shall be related to the design operating pressure by the ratio given in ISO 7751 or decided between the manufacturer and user. Criteria for failure There shall be no leakage or evidence of failure. Leakage at the end fitting, fitting blow-off or rupture of the hose adjacent to the fitting shall be considered as failures in the performance of the hose. 7.2 Measurement of deformation under pressure General procedure When tests for determining change in length and change in internal diameter are required, straighten the hose, lay it out horizontally for inspection and apply a hydrostatic pressure of 0,0 MPa (and when it is necessary 0,07 Mpa) to stabilize the hose. For the circumference measurements make reference mark(s) on the outer surface of the hose and maintain measuring tapes. For the length measurements maintain measuring tapes between the hose frontal flanges. Maintain the initial pressure of 0,0 MPa and make the appropriate measurements (see 7.2.2, and 7.2.4) at the reference marks. Apply the specified test pressure at the rate specified in and maintain it for 1 min before making the test measurements, which shall then be made as quickly as possible to avoid prolonging the test period. NOTE: The test pressure, the design Operating pressure and burst pressure will be specified in the appropriate hose product specification. Below the test pressure the hose deformation characteristics are to be measured. 14(47)

15 7.2.2 Change in length Measure the length between the frontal flange surfaces, with an accuracy of ±5 mm, using the measuring tape, at the initial pressure (0,0 MPa) and at the specified test pressure. Calculate the change in length, mm 1, expressed as a percentage of the original length, from the equation: l 1 - l 0 l = x 100 l 0 where l 0 l 1 is the distance, mm 1, between the hose frontal flange surfaces measured at the initial pressure; is the distance, mm 1, between the same the hose frontal flange surfaces measured at the specified test pressure. L0 L1 Δ L % Change in external diameter General The external diameter should preferably be determined from measurements of circumference made with an accuracy of 1 mm using a measuring tape Determination by measuring the change in external circumference Using the measuring tape, measure the circumference at the reference mark(s) at the initial pressure (0,0 MPa) and at the specified test pressure. Calculate the change in diameter, expressed as a percentage of the original diameter, from the equation: C 1 - C 0 D = x 100 C 0 Where: C 0 is the circumference at reference mark(s) measured at the initial pressure; C 1 is the circumference at reference mark(s) measured at the specified test pressure. D0 D1 Δ D % 15(47)

16 7.3 Burst pressure test Increase the pressure at a rate in accordance with until the hose fails. The position and mode of failure shall be recorded in the test report. This is not a standard test. 8 Test report The test report shall include the following particulars for each test undertaken: a) a full description of the hose tested; b) a reference to this International Standard, i.e. ISO 1402; c) the method used; d) the number of test hoses tested and the length of each test hose; e) the test pressure and rate of pressure increase and pressure intervals; f) the results obtained for each test hose; g) if the test hose fails, the position and mode of failure; h) any unusual features noted during the test; j) the date of the test. NOTE: Trelleborg can perform tests to ensure that the hose conforms to the requirements of the end user. 16(47)

18 INSPECTION AND TESTING (QUALIFICATION TEST) Trelleborg qualified the liner material and adhesion system by performing the following tests. The qualification tests were required one time, prior to the commercial production. This test is not a standard test. Adhesion Test Adhesion Test Method Trelleborg has provided the end user with two adhesion sample plates per liner material / adhesive system. The adhesion sample plates had the elastomer layer bonded to steel plate as shown below. Adhesion test has been performed by end user or a approved 3rd party laboratory. Test coupons with 25 mm width were cut from the plates using a water-cooled band saw or similar equipment. 18(47)

19 The coupons were tested by means of a 90 stripping method using a test fixture as shown below. The coupons has been totally immersed in the following media: Bitumen at 70 C for seven (7) days Water at 70 C for seven (7) days The coupons were withdrawn from the test media and immediately tested in the fixture maintaining the immersion temperature as close as possible. The test rate: 100 mm/min. Adhesion Test Criteria The liner and adhesive system has met the following minimum values for adhesion / tear strength. Initial adhesion strength of 8.8 kn/m width (50.0 lbs/inch width) tested at 20 C (no immersion). Adhesion strength of 4.4 kn/m width (25 lbs/inch width) after 7 days total immersion in bitumen at 70 C, and tested immediately after removal from immersion. Adhesion strength of 4.4 kn/m width (25 lbs/inch width) after 7 days total immersion in water at 70 C, and tested immediately after removal from immersion. 19(47)

20 ASTM D 746 Brittleness Test Trelleborg has performed a brittleness test per ASTM D 746 on all elastomeric hose components and submitted the results to the end user. All elastomeric hose components did not fail in a brittle manner when tested at -40 C. Slurry Jet Erosion (SJE) Test Trelleborg has provided the end user with one test plate per liner material. The test plate had a elastomer layer of 6.4 mm (0.25 ) thickness fully bonded to steel plate of 6.4 mm (0.25 ) thickness, with a dimension of 152 mm x 152 mm (6 x 6 ). Test coupons of 25.4 mm in width, 76.2 mm in length, and 12.7 mm in total thickness (1 x 3 x 0.5 ) was cut from the plate using a water-cooled band saw or similar equipment. SJE test has been performed by the end user or approved 3rd party laboratory. The wear data has been reviewed and approved. (by Materials Research department.) Burst Test Trelleborg has proven 3:1 safety factor by performing a burst test. A prototype rubber hose has been used for this purpose.
