The steel pipe is not only used to transport fluid and powdery solids, exchange heat, make mechanical parts and containers, it is also an economic steel. With steel pipe manufacturing architectural grid, pillars and mechanical support, can reduce the weight, save metal 20 to 40%, and can achieve the mechanization of factory construction. The use of steel pipe manufacturing bridge not only can save steel, simplify the construction, Steel Pipe but also can greatly reduce the area of protective coating, saving investment and maintenance costs.
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and seam steel pipe, sewn steel pipe referred to as straight seam steel pipe.
1. Seamless steel pipe according to the production method can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel pipe, hot expansion pipe, Steel Pipe cold spinning pipe and extrusion pipe.
Seamless steel pipe made of high quality carbon steel or alloy steel, hot-rolled, cold-rolled (pull) of the points.

2. Welded pipe because of its welding process is divided into different types of welding pipe, welding (resistance welding) pipe and automatic arc welded pipe, because of its different forms of welding into straight seam welded pipe and spiral welded pipe, because of its end shape For the round pipe and shaped (square, flat, etc.) welded pipe.
Welded steel pipe is made of rolled steel pipe to seam or spiral seam welded together, in the manufacturing method, and is divided into low-pressure fluid transmission with welded steel pipe, Steel Pipe spiral seam welded steel pipe, direct welded steel pipe, welded pipe. Seamless steel pipe can be used in various industries of liquid pressure pipelines and gas pipelines. Welding pipes can be used for water pipes, gas pipelines, heating pipes, Steel Pipe electrical pipes and so on.
Steel pipe according to pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.
Carbon tube can be divided into ordinary carbon steel pipe and high quality carbon structural pipe.
Alloy tube can be divided into: low alloy tube, Steel Pipe alloy structure tube, high alloy tube, high strength tube. Bearing tube, heat-resistant acid-resistant stainless steel tube, precision alloy (such as Kovar alloy) tube and high temperature alloy pipe.
Steel pipe is a special process of ordinary steel pipe for anti-corrosion treatment, so that the steel pipe has a certain anti-corrosion ability. Generally used for waterproof, rust, anti-acid, anti-oxidation and so on.
According to different needs, can be on the inner and outer wall of the corresponding anti-corrosion measures. Commonly there are: epoxy coal asphalt anti-corrosion, Steel Pipe epoxy coating anti-corrosion. Polyurethane coating anti-corrosion, IPN8710 drinking water pipe anti-corrosion, non-toxic coating anti-corrosion, anti-corrosion polymer coatings, steel pipe mortar corrosion. Steel pipe is mainly used in special requirements or harsh environments in the field of engineering.
