ASTM A500 Structural Steel Hollow Section is a cold formed welded and seamless carbon steel structural tube for structural applications.

Welded steel pipes are made by rolling steel plates or steel strips into tube shapes and welding them through a welding process. According to its weld form, it can be divided into straight seam welded pipe and spiral seam welded pipe.

ASTM A334 is a forged seamless carbon steel pipe that is one of the standard specifications for cryogenic applications.

A335 Grade P5b Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding adquire high hardnees and residual stress not recomended to put it directly in services that demand critical conditions.
