321h 347 ASME 150mm Welded Stainless Steel Pipe Large Diameter Q235A Q235C EN10217 - 7 - 2005

Description:
 
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 welding.Large diameter welded pipe for the most part adopts spiral welded.
 
Welded pipes are widely used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction.It is one of 20 key products of our country\'s development.
1,For liquid transportation:water supply and drainage.
2,For gas transmission:gas, steam, liquefied petroleum gas.
3,For construction: piling pipe, bridge; Dock, road, building structural tube, etc.
 
Welded pipe commonly used material for:Q235A,Q235C
Welded steel pipe is made of billet is steel plate or strip.Because of the different welding process is divided into furnace welded pipe, electrically welded tube and automatic arc welding tube.Because of its welding form of different can be divided into straight seam welded pipe and spiral welded pipe.Because of its shape is divided into circular welded pipe and alien (square, flat, etc) welded pipe.
