According to the production method, seamless steel pipe can be divided into: hot rolled seamless pipe, cold drawn pipe, precision steel pipe, hot expansion pipe, cold spin pipe and extrusion pipe, etc. Seamless steel pipe is made of high quality carbon steel or alloy steel, hot rolled, cold rolled (drawing)
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and welded steel pipe, welded steel pipe referred to as welded pipe. 1. According to the production method, seamless steel pipe can be divided into: hot-rolled seamless pipe, cold-drawn pipe, precision steel pipe, hot-expanded pipe, cold-spun pipe and extruded pipe, etc. Seamless steel pipe is made of high quality carbon steel or alloy steel, hot rolled, cold rolled (drawing). 2. Welded steel pipe is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe due to its different welding forms, which are divided into straight seam welded pipe and spiral welded pipe. Because of the shape of its end, it is also divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe. Welded steel pipe is made of rolled tubular steel plate welded by joint or spiral joint. In the manufacturing method, it is divided into welding steel pipe for low pressure fluid transmission, spiral welded steel pipe, direct coiled welded steel pipe, electric welded pipe, etc. Seamless steel pipe can be used in various industries of liquid pressure pipe and gas pipe, etc. Welding pipe can be used for water pipe, gas pipe, heating pipe, electrical pipe and so on.
