How we produce ssaw steel pipe?
Listing some notes You must know
※ Oiled marking: 
Steel after passing wrer oiled to prevent corrosion,and according to user requirements for making.
※ Leveling Milling: 
The flat steel anvil machine so that the origal curl,and then thouth the edge milling machine for two-sided steel milling,so as to meet the requirements of the plate width,plate edge parallelism and groove shape.
※ Shear molding: 
The steel plate production line along the outer edge of the spiral curl into a tube.
※ Butt cut: 
Double-sided submerged arc welding using advanced technology to pre-welding,internal welding,outside wilding.The welded steel pipe using a plasma-foot cut to specification length.
Which specification of SSAW pipe we can offer?
There are some detailed specifications of spiral steel pipe that we produce now for our customers all over the world.

 Or OEM sized , the biggest OD we could do is 3048mm.

Application - line pipe for use in pipeline transportation systems in the petroleum and
natural gas industries;
- applies to pipe piles in which the steel cylinder acts as a permanent
load-carrying member, or as a shell to form cast-in-place concrete piles;
- predominantly used in the construction of chemical plant, vessels, pipe work
and for general mechanical engineering purposes;
- applies to structural hollow sections and pressure purposes etc.
