Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the variety specifications of welded steel pipes have been increasing, and they have replaced seamless steel pipes in more and more fields. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld. Classification by production method: Process classification - arc welded pipe, resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.

Product introduction
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than seamless steel pipe.

Product Details
The production process of straight welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe, and welded pipe with larger diameter can be produced with narrower billet, and welded pipe with different diameter can also be produced with billet of the same width. However, compared with the straight seam pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is lower.
