ASTM A333 Grade 3&Grade 6 seamless pipe for Low-Temperature Manufacturing Process :

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.

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.

● Plastic caps plugged at the two sides of pipe ends

● Should be avoided by the steel strapping and transport damage

● Bundled signs should be uniform and consistent

● The same bundle(batch) of steel pipe should be came from the same furnace.

● The steel pipe has the same furnace number, the same steel grade, the same specifications.

Our packing can meet any needs of the customers
