Large-diameter Welded Pipe
Large-diameteris the pipe welds, raw materials are mainly steel sheet and strip, large diameter straight seam welded steel pipe is used, the higher productivity of the kinds of steel, more used in more low-cost steel products one. Large diameter spiral welded steel pipe is used, compared to the straight pipe joints, mechanical strength of the products is relatively high, to save raw materials, but the production is slow. The product is widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the products of China's 20 key development. For the transport of liquids: water supply, drainage. For gas transportation: gas, steam, LPG. For structural purposes: as piling pipe for bridges; piers, roads, pipes and other building structures.
