For PSL1 pipe, manufacturer shall establish and follow documented procedures to maintain a. Different manufacturing type API 5L specification covers the manufacturing types in welded and seamless. Rdition Eng-Tips staff will check this out and take appropriate action.

In addition, changes were made to Section This standard is not applicable to cast pipe. The flattening test method is used to verify the deformation performance of line pipe to the erition size, and display its defects. It’s easy to join and it’s free. Specially for the big diameter steel pipe, SAW pipe gains a great advantage.

API 5L steel line pipe adopts different steel grades, generally are Gr. Jointers need not be hydrostatically level, provided that the portions of pipe used in making the jointers were successfully hydrostatically tested prior to the joining operation.
