The bending of a metal pipe means bending a full-section metal straight pipe around a specified radius and a grooved bend until the bending angle reaches the value specified by the relevant product standard.
The test method is as follows:
1. The test should generally be carried out at a room temperature ranging from 10 ° C to 35 ° C. For tests requiring control under controlled conditions, the test temperature shall be 23 ° C ± 5 ° C.
2. Bend the tube specimen without the filler by the bending test machine. During the test, ensure that the bending deformation section of the specimen is in close contact with the bending of the metal tube until the specified bending angle is reached.
3. When performing the bending test of the welded pipe, the position of the weld bead relative to the curved plane shall comply with the requirements stipulated by the relevant product standards. If no specific requirements are specified, the weld shall be placed at 90° to the curved plane. The position of the curved neutral line.
4. The description of the bending test results should be based on the requirements of the relevant product standards. When not specified in the product standard, in the absence of a magnifying glass, if there is no visible crack, it should be assessed as qualified.
