Alloy Steel Seamless Pipe OD 273.1 * THK 6.35% L 6000 MM API

Steel pipe (Steel pipe) is used to transport fluid and powdery solids, exchange heat, manufacture mechanical parts and containers, and is also an economical steel. The development of steel pipe production technology began with the rise of bicycle manufacturing industry, the development of oil in the early 19th century, the manufacture of ships, boilers and aircraft during the two world wars, the manufacture of thermal power boilers after the second world war, the development of chemical industry and the drilling and transportation of oil and gas. According to the production method, steel pipe can be divided into two categories: seamless steel pipe and sewn steel pipe, sewn steel pipe and spiral welded pipe.

Classification of steel pipes
Method of production
According to the production method, steel pipe can be divided into two categories: seamless steel pipe and sewn steel pipe.
1. seamless steel pipe can be divided into hot-rolled seamless pipe, cold-drawn pipe, precision steel pipe, hot-expanding pipe, cold-rotating pipe and extrusion pipe according to the production method.
Seamless steel pipe made of high-quality carbon steel or alloy steel, hot-rolled, cold-rolled (pull) 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 process. Because of its different welding form, it can be divided into straight seam welding pipe and spiral welding pipe.
Steel pipe welded steel pipe is made of rolled steel plate to weld the joint or spiral joint. In the manufacturing method, it is divided into welded steel pipe for low pressure fluid transportation, spiral welded steel pipe, direct rolled steel pipe, welding pipe and so on. Seamless steel pipe can be used in various industries of liquid pressure pipes and gas pipes and so on. Welding pipe can be used for water pipeline, gas pipeline, heating pipe, electrical pipe and so on.
