A welded pipe, also known as a welded steel pipe, is a steel pipe made of steel plates or strips that are welded after being curled and formed. The production process of welded steel pipes is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is small, but the general strength is lower than that of seamless steel pipes. 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 continued to improve, and the varieties and specifications of welded steel pipes have increased day by day, replacing unfinished steel pipes in more and more fields. Sewing steel pipe. Welded steel pipes are divided into straight seam welded steel pipes and spiral welded steel pipes according to the form of the weld.
1. Classification of welded steel pipes:
Welded steel pipes are classified by use: According to use, they are divided into generally welded steel pipes, galvanized welded steel pipes, oxygen-blown welded steel pipes, wire casings, metric welded steel pipes, idler pipes, deep well pump pipes, automotive pipes, transformer pipes, and electric welding pipes. Thin-walled pipes, electric welded special-shaped pipes, and spiral welded steel pipes.
2. Application scope of welded steel pipe:
Welded steel pipe products are widely used in boilers, automobiles, ships, lightweight structural door and window steel for construction, furniture, various agricultural machinery, scaffolding, wire conduits, high-rise shelves, containers, etc. All can meet customer requirements, and special specifications of welded steel pipes can be processed according to user requirements.
