Test requirement: tension test, flattening test, flaring test, hardness test, hydrostatic or nondestructive electric test,etc.

ASTM A333 Grade 3 seamless pipe for Low-Temperature Manufacturing Process :A333 low temperature pipe hot-rolled (squeeze seamless steel tubes): tube perforation →  heated three-roll cross-rolling, continuous rolled or extruded-cannula → sizing (or reducing) steel tube straightening → cooling water pressure test (or testing) → tags → storage. Drawing (rolling) seamless steel pipe: pipe perforated → heat →  start → annealing pickling oil (copper) → multi-pass drawing (cold rolled) steel tube heat treatment straightening → hydrostatic test (testing) → tags → storage.
A333 Seamless management of weight formula:[(OD-wall thickness) *wall thickness]*0.02466=kg/meters of wall thickness (weight per meter)
