Spiral Pipe Production Process: is a strip coil as raw material, often warm extrusion molding, an automatic double-sided double-wire submerged arc welding process spiral seam steel pipe welded together. Spiral steel pipe features: Longitudinal simple production technology, high efficiency, low cost, rapid development. Spiral Welded Pipe Longitudinal strength generally higher than high, can use a narrow billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, with the same length of straight seam tube compared to the weld length of 30 ~ 100%, and a lower production rate. Therefore, the smaller diameter pipe actually use straight seam welding, large diameter spiral welded pipe is mostly used Spiral and its standard categories: pressure fluid transport with spiral submerged arc welded pipe (SY5036-83) is mainly used for transport of oil, natural gas pipeline; pressure fluid transport with spiral seam high frequency welded pipe (SY5038-83), Overlap welding method using high frequency welding, for pressure fluid transmission high-frequency welded spiral seam steel pipe. Pipe pressure capability, good plasticity, easy to welding and machining molding; the general low-pressure fluid delivery with spiral submerged arc welded pipe (SY5037-83), using double-sided or one-sided weld automatic submerged arc welding for the rule of law into the water, gas, air and steam with the general low-pressure fluid transmission pipe submerged arc weldingSpiral Pipe Production Process: is a strip coil as raw material, often warm extrusion molding, an automatic double-sided double-wire submerged arc welding process spiral seam steel pipe welded together.
