According to the material Steel Pipe can be divided into: carbon tubes and alloy tube, stainless steel tube etc.. Carbon pipe can be divided into ordinary Carbon Steel Pipe and high quality carbon structure pipe. The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless steel pipe, precision alloy (such as can be cut alloy) tube and high temperature alloy tube, etc..
According to the production method
Steel pipe according to the production method can be divided into two categories: Seamless Steel Pipe and pipe joints, pipe joints as Welded Steel Pipe.
1. Seamless steel pipe according to the production method can be divided into: hot-rolled seamless tube, cold drawn tube, precision steel tube, thermal expansion tubes, cold spinning tube and pipe extrusion.
Seamless steel pipe made of high quality carbon steel or alloy steel, hot-rolled, cold-rolled (drawn) branch.
Bundles of steel tubes
Bundles of steel tubes
2. Welded steel pipe for the different welding process is divided into the furnace pipe, welding (ERW) pipes and automatic arc welding, because of the different welding form is divided into two kinds of longitudinal and spiral welded pipe, due to the shape of the end and circular welded pipe and shaped (square, flat) welded pipe.
Welded steel pipe is rolled into a tube shaped steel plate to butt or spiral seam welding and, in the manufacturing method, voltage liquid transportation by welding steel pipe, spiral seam welded steel pipe and directly roll welded steel pipe, welded steel pipe. Seamless steel pipe can be used in a variety of industries, such as liquid pressure pipe and gas pipeline. Welding pipe can be used for water pipelines, gas pipelines, heating pipes, electrical appliances, etc..
