Large diameter welded steel pipe often refers to the out diameter with more than 1000mm. large diameter steel pipe use is generally more widely, generally used for large-scale pipeline projects, water gas engineering, pipe network construction of large projects.Large diameter steel pipe production process is generally a result of these processes: heating, piercing, bending, seam, weld inside and outside welding, straightening, flat top multi-channel processes, to achieve the American Petroleum Institute standards. Large diameter structural steel pipe used for large multi-building among the main supporting part to do, such as a bridge piling, underwater piling, piling high-rise buildings.Large diameter steel pipe has good adhesion, corrosion resistance, which can be resistant to acid, alkali and other chemical corrosion, non-toxic, does not rust, abrasion resistance, impact resistance, permeability, smooth pipe surface will not adhere to any substance, can reduce the transmission of resistance, large diameter carbon steel pipe to improve traffic and transportation efficiency, reduce delivery pressure loss. Coating solvent-free, no leaking substances, and thus will not contaminate the transmission medium, thus ensuring fluid purity and hygiene at -40 to +80 range can be used alternately hot and cold cycles, aging, no cracks, which can in cold areas such harsh environments.
