Mechanical properties The mechanical properties of the pipes will depend on: (1)The Bauschinger effect, which in turn depends on: (2)The post-treatment (full-body post-heating/stress relieving post-heating) that is sometimes performed by the client (3)The angle of the weld on spiral tubes (this will influence the direction of the tensile test with respect to the rolling direction) The evolution of the mechanical properties - and in particular of the difference in yield strength between the sheet and the pipe - is specific for each process. It is therefore very important to indicate both the forming and the welding process as well as the aforementioned sheet/pipe difference. An agreement between ArcelorMittal and the client on the mechanical properties to be guaranteed must be reached prior to the delivery. The mechanical properties specified, in the thickness ranges proposed and supplied as described, enable the requirements of API 5L PSL2 standard to be met on the finished pipe. | ||||||||||||||||
