What Are The Classifications Of Steel Pipes
Steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. Next, I will introduce to you the classification of steel pipes.
According to Material
Steel pipes are made of different materials. If classified according to the material of steel pipes, they can be divided into the following three types of steel pipes, namely carbon steel pipes, alloy pipes, and stainless steel pipes.
According to the production process
Steel pipes can be manufactured according to different production processes, which are mainly divided into two production processes, namely seamless steel pipes and welded steel pipes. Among them, welded steel pipes are divided into submerged arc welding and resistance welding due to different welding methods. In addition, welded pipes can be divided into straight seam welded pipes and spiral welded pipes. Today, due to production technology barriers, seamless pipes cannot be made into large-diameter steel pipes, while welded pipes can be produced through welding. Therefore, in order to meet the needs of daily production, people often choose large-diameter welded pipes.
According to surface treatment process
In addition to the two more common classification methods above, steel pipes can also be divided into galvanized pipes, anti-corrosion pipes and black paint pipes according to the surface treatment process. Galvanized pipe is a process produced to meet the anti-corrosion needs of carbon steel pipes. However, during use, the galvanized layer will cause the coating to fall off and accumulate in the pipe, which affects the transportation of materials in the pipe. Therefore, when transporting water, , oil and gas industries are not commonly used.
