Spiral steel pipes are widely used industrial, construction and other industries . It’s raw mataerial is strip steel rolled plate , through normal temperature extrusion molding, with automatic double wire welding double-sided submerged arc welding technology with the spiral seam pipe. Mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction.
Spiral steel pipe for liquid transportation: water supply and drainage. For gas transportaion:gas, steam, liquefied petroleum gas. For structure: piling pipe, bridge; Dock, road, building structural tube, etc. It’s has played a large role in conveying gas and transporting.
Spiral steel pipe confined fluid conveying with spiral seam submerged arc welding steel tube is mainly used for conveying oil, natural gas pipeline; Pressurized fluid conveying with high frequency welding steel pipe, spiral seam with high-frequency welded lap welding method, used in pressurized fluid conveying spiral seam high frequency welding steel pipe. Steel tube confined ability, good plasticity, easy to welding and processing molding; General low-pressure fluid conveying spiral seam submerged arc welding steel pipe, use double-sided automatic submerged arc welding or welding by one side into the legal system for water, gas, air and steam general low-pressure fluid conveying with submerged arc welding steel pipe.
The strength of SSAW steel pipe is higher than straight seam welded pipe, use a narrow billet production of larger diameter welded pipe, you can also use the same width of billet in the production of different pipe diameter welded pipe. But compared with the same length of straight seam pipe, weld length by 30 ~ 100%, and the production speed is low. As a result, a small diameter welded pipe are mostly with straight seam welding, large diameter welded pipe for the most part adopts spiral welded.
Spiral steel pipe is closely related to our life, our drainage, exhaust gas, gas, gas is inseparable from the spiral steel pipe.
