Packing

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.Our packing can meet any needs of the customers.

· 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.
