Lateral bending test
Transverse bending test is applied to the outer diameter of not less than 60mm of the metal tube (including metal pipe seamless pipe and welded pipe bending test specimen and transverse) arc diameter not less than 400mm metal pipe transverse rectangular specimen.
The metal pipe transverse bending test can replace the flattening test, can effectively assess the seamless pipe and welded pipe flattening process performance, provides a detailed and reliable basis for the design and application of large diameter thick wall metal pipe. A standard term, the main metal pipe, transverse and horizontal rectangular arc sample sample, positive bending, reverse bending, lateral bending, for equipment, testing machine to support roll bending device using two supporting rollers and bending pressure head, and the supporting rollers and bending head should have enough stiffness and hardness.
