 Spiral Pipe Spiral Pipe pump tube fabric machine pvdf tube 

 With φ219-φ3620 spiral arc welding steel pipe five sets of annual production capacity of 100,000 tons, the products: large-diameter spiral welded pipe, spiral steel pipe, thick-walled spiral welded pipe, spiral welded pipe 
 , Small-diameter spiral steel pipe, corrosion spiral steel pipe, spiral submerged arc welded pipe, large diameter submerged arc spiral. The products are widely used in water engineering, stone, chemical industry, chemical industry, power industry, agricultural irrigation, urban construction 
 In order to facilitate the majority of customer shipping, the purchase of a large gantry crane and steam cranes and fleet 24 hours. Contract, keeping promises units. 

 Double-sided spiral submerged arc welding technology, narrowband (board) volume continuous welded from steel pipes. Of West-East and other oil and gas pipeline projects, a wide range of applications, is the main tube of oil and gas pipeline project. 
 Spiral steel pipes are widely used in natural gas, petroleum, chemicals, electricity, heating, drainage, steam heating, hydropower penstock, thermal power, water and other long-distance pipelines, piling, dredging, bridges, steel and other engineering fields. Longitudinal production process is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe specifications are generally higher than the Longitudinal and spiral welded pipe specifications can narrow the billet production of large diameter welded pipe, spiral welded pipe specifications can also use the same width of the billet production of different diameters of pipe. However, compared with the same length of straight seam pipe, spiral welded pipe specifications weld length increased by 30 to 100%, and spiral welded pipe specifications lower production rate. Therefore, the smaller diameter pipe mostly straight seam welded pipe of large diameter are mostly spiral welded pipe specifications. 

 A low pressure fluid conveyance of submerged arc welded spiral welded pipe specifications (SY5037-2000) is based on hot-rolled steel strip coils for tube, often warm spiral shape, using double-sided automatic submerged arc welding or single-sided welding into the legal system with The low pressure fluid such as water, gas, air and steam for the conveyance of submerged arc welded pipe. 
 (2) low pressure fluid tube with high-frequency spiral welded pipe specifications (SY5039-83) is hot-rolled steel strip coils, often warm spiral shape
