Page 10: Overview
Overview Tensile Tester The tensile tester is a hydraulic hand pump machine that is used to test fusion joint coupons. The coupon is loaded into the machine and the hand pump is used to pressure a hydraulic cylinder that pulls the fusion coupon to test it. IMPORTANT: The tensile tester should only be used to perform tests on coupons that were created from fusions of like pipes. -
Page 11: Directional Valve
Overview Pressure Relief Valve Used to unload pressure in the hydraulic cylinder. Push toward the machine to unload pressure and pull toward to close the valve. TX04067-5-25-10 Directional Valve The directional valve that controls the direction of the cylinder. Move the valve to the left to move the cylinder left and move the valve to the right to move the cylinder right. -
Page 12: Template
(% of FUSION JOINT) Templates are available in 95%, 90%, and 85% width relationships with others upon request. The In Field Tensile Tester includes the 95% coupon template to test the fusion joint reduced area for strength that is equal or exceeds the strength of the pipe material ensuring a high performance fusion joint. -
Page 13: Additional Tools
Overview Additional Tools There are some tools that will be required (not included) to complete the preparation of the coupon for testing. • A reciprocating saw with a coarse woodcutting blade. • A 1/2" chuck, heavy duty, 650 rpm drill. •... -
Page 14: Operation
Operation Read before Operating Before operating this machine, please read this manual thoroughly and keep a copy with the machine for future reference. TX00838-1-5-96 Attach Template to Pipe (4" or Larger) Place the template on the pipe, saddle side down. Align the alignment marks on the template with the center of the fusion joint. -
Page 15: Attach Template To Pipe (2" To 3" Pipe)
Operation Attach Template to Pipe (2" to 3" Pipe) Place the template on the pipe, saddle side down. Align the alignment marks on the template with the center of the fusion joint. Attach the two U-bolts around the pipe and through the template with the washers and nuts. -
Page 16: Drill Holes In The Pipe
Operation Drill Holes in the Pipe Read and understand the all instructions provided with your drill and saw. Failure to follow all the drill and saw instructions, may result in electric shock, fire and/or serious personal injury. With the drill bit provided, drill the four innermost large holes first then the remaining holes through the pipe wall. -
Page 17: Saw The Coupon
Operation Saw the Coupon Mark the saw cuts to be made with a paint pen, grease pencil or other legible marking instrument. Read and understand the all instructions provided with your drill and saw. Failure to follow all the drill and saw instructions, may result in electric shock, fire and/or serious personal injury. -
Page 18: Remove The Coupon
Operation Saw the Coupon (cont'd) For smaller pipe, saw out the section of pipe and then saw the pipe in half long ways so that you have your holes all on one side of the cut pipe. Saw cut one end of the pipe so that it is 1.25" away from the edge of the outer hole. -
Page 19: Inspect The Coupon
Operation Inspect the Coupon Inspect the narrow sections of the coupon. The surface finish on all four narrow section holes should be smooth. Inspect for notches or gouges in the narrow section holes. Notches or gouges could effect the test results. If notches or gouges exist, cut another coupon from the pipe. -
Page 20: Perform Test
Operation Perform Test Move the directional valve to the right position. Slowly pump the handle until the coupon breaks or until you reach the end of the cylinder stroke. The flow of the pump is limited in this direction to provide a slow tensile load to the coupon. Remove the coupon. -
Page 21: Inspect Coupon/Interpret Result
Operation Inspect Coupon/Interpret Result A) The coupon breaks in the joint which is a failing result. B) The coupon stretches in the pipe which is a passing result. C) The coupon breaks in the pipe which is a passing result. If the joint of the coupon does not pass, examine that you are doing everything properly and isolate the cause of the failing result. -
Page 22: Maintenance
Maintenance Preventative Maintenance To insure optimum performance, the machine must be kept clean and well maintained. With reasonable care, this machine will give years of service. Therefore, it is important that a regular schedule of preventive maintenance be kept. Store machine inside, out of the weather, whenever possible. TX00428-8-10-95 Cleaning the Machine Clean the machine with a soap and water wash as needed. -
Page 23: Bleeding The Hydraulic System
Maintenance Bleeding the Hydraulic System Make sure the hydraulic pump fluid has been filled and tilt the machine 45 degrees so that the pump is facing up. Pump the machine moving the cylinder in and out completely several times. When bled, the machine should move immediately when pumped. - Page 24 Hydraulic Fluids Hydraulic Fluids The use of proper hydraulic fluid is mandatory to achieve maximum performance and machine life. Use a clean, high quality, anti-wear hydraulic fluid with a viscosity index (VI) of 135 minimum. It should have a maximum viscosity of 500 cSt (2000 SSU) at startup (ambient temperature) and a minimum viscosity of 13 cSt (65 SSU) at the maximum fluid temperature (generally 80°F above ambient).
