Pipe Inspection,Testing & Marking Requirements to Ensure use dn1400 welded pipe steels

Straightness Tolerances for Pipe. The carbon steel pipe standards require only that the finished pipe shall be reasonably straight. ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths. Generally, the thumb rule is Pipe Welding TutorialPipe welding makes connecting pipe much easier than threading it. It's also less costly.
