ASTM API 5L X80 Seamless and Welding PSL2 Steel Pipe/Tube
ASTM API 5L X80 seamless and welding PSL2 Steel pipe/tube, the steel shall be killed and made according to fine grain practice. The coil or plate used for the manufacture of PSL2 API 5L X80 pipe shall not contain any repair welds. The width of the coil or plate used for the manufacture of helical seam pipe shall not be less than 0.8 times or more than 3.0 times the specified outside diameter of the pipe

ASTM API 5L X80 Seamless and Welding PSL2 Pipe/Tube Weld Ability:
If agreed, the Katalor will supply API 5L X80 weld ability data for the type of steel concerned or perform weld ability tests, for which the details for carrying out the tests and the acceptance criteria shall be as API 5L X80 specified in the purchase order.
However, account should be taken of the fact that the behavior of the API 5L X80 steel during and after welding is dependent not only upon the API 5L X80 steel composition, but also upon the welding consumables used and the conditions of preparing for, and carrying out, welding.
