Welded pipe, also known as welded steel pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. Welded steel pipe has a simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but its general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have increased day by day and replaced seamless steel pipes in more and more fields. Seam steel pipe. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld seam.
1. Classification of welded pipes
Welded pipes are classified according to their uses: according to their uses, they are divided into generally welded pipes, galvanized welded pipes, oxygen-blown welded pipes, wire casings, metric welded pipes, idler pipes, deep well pump pipes, automotive pipes, transformer pipes, electric welding thin-walled pipes, electric welding Special-shaped pipes, and spiral welded pipes.
Second, the scope of application of welded pipe
Welded pipe products are widely used in boilers, automobiles, ships, lightweight door and window steel for construction, furniture, various agricultural machinery, scaffolding, wire threading pipes, high-rise shelves, containers, etc. Can meet customer requirements, special specification welded pipe can be processed according to user requirements.
