Pipe according to the production methods can be divided into two categories: seamless steel pipe and welded steel pipe, welded steel pipe referred to as straight-seam steel pipe.
1 seamless steel pipe according to the production methods can be divided into: hot-rolled seamless pipe,cold drawn tube,precision steel pipe,thermal expansion steel pipe,cold spinning tube and squeeze tubes.
Seamless steel pipe with high quality carbon steel or alloy steel are produced according to hot-rolled and cold drawn method.
2 welded steel pipe is divided into furnace pipe,welded (ERW) pipes and automatic arc welded pipe because of welding process method
Welded steel pipe is rolled into a tube-shaped steel plates on the seam or spiral seam welded together,it is divided into low pressure liquid delivery welded steel pipe,spiral welded steel pipe,straight welded steel pipe,welded pipe in the manufacturing method.Seamless steel pipe can be used in various industries liquid pressure pipelines and gas pipelines.Welded pipes can be used for water pipes,gas pipes,heating pipes,electrical pipes.
