Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. It is possible to produce a welded pipe with a large diameter by using a narrow blank, and it is also possible to produce a welded pipe having a different pipe diameter by using a blank of the same width. However, compared with the straight pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is low.
Products are widely used in water supply engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction.
For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas.
