How To Do The Bending Test Of Erw Pipes Youtube As one of the most common tests of erw pipes, the bending tests will be carried out after finishing the production. do you know how to do the bending tests?. The bending test assesses the ductility and integrity of the erw tube. according to astm a53, steel pipes must be able to withstand bending without cracks or defects. this test ensures that the steel tube can withstand bending stresses without compromising its structural integrity. on pipe diameters nps 2 and less, a bending test is performed.
Bend Tests 2. destructive test. flattening test. cut about 100mm welded pipe, place it under the hydraulic press, the position of the weld is perpendicular to the direction of the hydraulic press, start the oil pressure, slowly press the welded pipe, press it to 3 4 of the diameter, and check whether the weld is cracked. if there is no crack, weld the. The tensile test is done to check the yield and ultimate tensile of the pipe. if required by the purchaser or by standard high or low temperature tensile tests are also performed. bend test guided bend test is used to check the integrity of weld joint ; the flattening test examines the ability of plastic deformation in a pipe. The electric resistance welding (erw) process is a highly effective method of producing carbon steel pipes for various industries. this welding process involves passing an electric current through the metal to create heat and pressure, which welds the two pieces together. the resulting product is a strong, reliable pipe that is able to. Flexible forming excellent (ffx) forming of electric resistance welding (erw) pipe is an advanced roll forming method. in order to understand ffx forming mechanism and set reasonable roll parameters, five point bending process and springback process for preforming section of erw pipe ffx forming are analyzed.

Erw pipe process performance inspection: 1. bending test: bending test should be carried out on steel tubes with an outer diameter less than or equal to 50mm. the bending angle is 90°, the bending radius is equal to 6 times the outer diameter of the tube. the weld is located at the outermost part of the bend. defects such as fracture openings. 2. Welded (erw) carbon and alloy mechanical steel tubing, whether used in the as welded condition or after further processing. unlike pipe, mechanical tubing is not intended for the transmission of fluids, except in fluid power applications, and is produced to exact rather than nominal od or wall dimensions, and to exacting tolerances.
