Construction Welded Steel Pipe ERW Steel Pipe Structure Steel pipe Construction Welded Steel Pipe because of welding into a straight line hence the name, which according to the use of different, and different back-channel production process (roughly can be divided into scaffolding pipe, fluid pipe, wire casing, bracket tube, guardrail pipe and so on). The characteristics of internal and external anti-corrosive spiral steel pipe for water supply, corrosion resistance, non-leakage, high toughness, excellent flexibility, good resistance to scratches, with good rapid crack transfer resistance. Construction Welded Steel Pipe is to strip coil as raw material, regular temperature extrusion molding, automatic double-wire double-sided submerged arc welding process welded into the Construction Welded Steel Pipe. The Construction Welded Steel Pipe used in building structure has the characteristics of relatively simple process, which is divided into high frequency welding, submerged arc welding, resistance welding, welding, spiral welding, etc., and has a wide range of applications in civil construction, petrochemical, light industry and other departments. Mostly used to transport low-pressure fluids or to make a variety of engineering components and light industrial products. Straight seam anti-corrosive steel pipe generally refers to the use of special technology for ordinary steel pipe anti-corrosion treatment, so that Construction Welded Steel Pipe has a certain anti-corrosion capacity, generally used for waterproof, anti-rust, anti-acid and alkali, anti-oxidation and other characteristics. The process of straight seam anti-corrosive steel pipe base material is submerged arc welded Construction Welded Steel Pipe and high frequency Construction Welded Steel Pipe. Anti-corrosion submerged arc welded Construction Welded Steel Pipe caliber in more than 325, anti-corrosive high-frequency Construction Welded Steel Pipe caliber below 426.

The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are increasing, and seamless steel pipes are replaced in more and more fields. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes
