High Production Efficiency Of Welded Steel Pipe
Sep 21, 2017


Welded steel pipe used in the billet is steel plate or strip, because of its different welding process and divided into furnace welded pipe, welding (resistance welding) pipe and automatic arc welded pipe. Because of its different types of welding is divided into straight seam welded pipe and spiral welded pipe two. Because of its end shape is divided into circular welded pipe and shaped (square, flat, etc.) welded pipe.

Welded steel pipe also known as straight seam welded pipe. Welded Steel Pipes refers to steel strips or steel plate bending deformation for the shape of the round, square and other welded into the surface, the seam of the steel pipe. The billet used in welded steel pipe is steel plate or strip.

Weld Steel pipe According to the characteristics of weld can be divided into: straight seam welded pipe and spiral welded pipe. Their characteristics: The production process is simple, Welded Steel Pipes the production efficiency is high, the cost is low. The smaller caliber welded pipe mostly adopts the straight seam welding, and the large diameter welded pipe is mostly spirally welded.

Characteristics of welded steel pipe: In the steel pipe, straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of welded steel pipe is usually higher than that of straight seam welded pipe, Welded Steel Pipes which can produce welded pipe with a large pipe diameter with narrow billet, and can produce pipe with different diameters with same width. However, compared with the equivalent length of the straight seam tube, the weld length increases the 30%~100%, and the production speed is relatively low. Therefore, the smaller-caliber welded pipe generally uses straight seam welding, Welded Steel Pipes large-caliber welded pipe is mostly used in the form of spiral welded pipe.

The welded steel pipe is mainly used for transporting oil and natural gas pipelines; high frequency welded pipe (sy5038-83) with spiral seam for pressure fluid conveying, mainly welded by high-frequency lap welding, for high frequency welded pipe of spiral seam for pressurized fluid conveying. Welded Steel Pipes Steel pipe bearing capacity is strong, good plasticity, easy to weld and process molding; general low pressure fluid conveying spiral seam submerged arc welded steel pipe (sy5037-83), the use of double-sided automatic submerged arc welding or single-sided welding method for water, gas, air and steam, such as the general low-pressure fluid transport submerged arc welded steel pipe.
