Steel pipe can be divided into two categories according to the production method: seamless steel pipe and welded steel pipe, welded steel pipe is referred to as welded pipe.
1. Seamless steel pipe can be divided into: hot rolled seamless pipe, cold drawn pipe, precision steel pipe, hot expansion pipe, cold spinning pipe and extrusion pipe, etc.

Seamless steel tube is made of high quality carbon steel or alloy steel, hot rolled, cold rolled (drawn) points.
2. Welded steel pipe is divided into furnace welding pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding form is divided into straight seam welding pipe and spiral welding pipe, because of its end shape is divided into round welding pipe and shaped (square, flat, etc.) welding pipe.
Welded steel pipe is made of rolled tubular steel plate welded to the seam or spiral seam. In terms of manufacturing methods, it can be divided into welding steel pipe for low-pressure fluid transportation, spiral seam welding steel pipe, direct coil welding steel pipe, electric welding pipe and so on. Seamless steel pipe can be used in various industries, such as liquid pressure pipe and gas pipe. Welded pipes can be used for water pipelines, gas pipelines, heating pipes, electrical pipes and so on.
