At present China is the world's largest welded steel tube production and exporter.China seamless pipe have more market share in the world.

The welded pipe price rising of other countries,but our price is low.


Straight seam welded pipe production process is simple,efficient production,low cost,Developing Faster.The strength of the spiral welded pipe is generally higher than straight seam welded pipe.Use a narrow billet production of larger diameter welded pipe.You can also use the same width of different diameter welded pipe billet production.But compared with the same length of straight seam pipe,weld length increased 30-100%,and the production speed is low.Therefore,relatively small diameter welded pipe are mostly with straight seam
