Spiral steel pipe is the industrial, construction and other industries widely used kind of steel. It is a strip coil as raw material, often warm extrusion molding, with automatic double-sided submerged arc welding process wire spiral welded steel pipe. Mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. Spiral steel pipe for the transport of liquids: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; docks, roads, buildings and other structures tube. Spiral Pipe Plant it in the transportation of gas, transportation has played a significant role.
Spiral steel pipe pressure transmission fluid with spiral submerged arc welded pipe is mainly used to transport oil, natural gas pipelines; pressure transmission fluid with frequency spiral welded steel pipes, lap welding method with high frequency welding, pressure fluid transport frequency spiral welded steel pipe. Strong pressure steel, plastic, and easy welding and machining molding; generally low pressure liquid delivery spiral submerged arc welded pipe, using double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam low pressure liquid delivery SAW pipe.
Spiral Pipe Plant Longitudinal generally higher than its strength, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. But with the same length of straight pipe joints than weld length of 30 to 100%, and lower production rate. Therefore, the smaller diameter pipe is mostly a straight seam welded, large diameter spiral welded pipe is mostly used.
