spiral welded pipe

spiral welded pipe adopts double-sided submerged arc spiral welding technology, narrow strip (plate) coil continuous welded steel pipe. The advantages are: high compressive strength, high impact strength, high safety performance, longer service life

Product Details

PRODUCT INFORMATION

The strength of SSAW spiral welded pipe is generally higher than that of straight seam 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. SSAW spiral welded pipe nominal diameter, also known as the average outside diameter. This is due to the fact that the wall of the metal pipe is very thin, and the outer diameter of the pipe is almost the same as the inner diameter of the pipe, so the average value of the outer diameter of the pipe and the inner diameter of the pipe is called the diameter of the pipe.

Spiral steel pipe is widely used in natural gas, petroleum, chemical industry, power, heat, water supply and drainage, steam heating, pressure steel pipe for hydropower station, thermal power generation, water and other long-distance transmission pipelines and piling, dredging, Bridges, steel structures and other engineering fields.
