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.
