从装备能力、制造流程、产品品种、规格和性能水平等方面针对日本JFE公司和新日铁住金两家主要的钢铁公司在高等级直缝埋弧焊管线钢管方面进行了调研。两家公司均为集成化钢铁联合生产企业,可实现从炼钢、轧制、制管到内外涂覆的全流程钢管一贯制制造。JFE公司UOE焊管、螺旋焊管和ERW焊管的年产能为112、20和75万t,新日铁住金的UOE焊管、螺旋焊管和ERW焊管的年产能分别为100、27和82万t。两家公司在直缝埋弧焊管方面均已开发了X100/X120高强度管、X60~X120抗大应变管、X70抗酸管、X80低温管、X80厚壁管、X65深海用厚壁管等高等级管线管产品,并应用于诸多世界主要管线工程。
In terms of equipment capabilities, manufacturing processes, product variety, specifications and performance levels, two major steel companies, Japan JFE and Nippon Steel & Sumitomo Metal, conducted research on high grade LSAW pipe. Both companies are integrated steel integrated manufacturing enterprises, which can achieve the whole process of steel pipe manufacturing from steelmaking, rolling, pipe manufacturing to internal and external coating. JFE UOE pipe, spiral welded pipe and ERW pipe production capacity of 112,20 and 750,000 t, Nippon Steel Sumitomo UOE pipe, spiral welded pipe and ERW pipe production capacity of 100,27 and 820,000 t respectively. The two companies have developed X100 / X120 high strength pipe, X60 ~ X120 anti-big strain pipe, X70 acid resistant pipe, X80 low temperature pipe, X80 thick-walled pipe, X65 deep-sea thick pipe etc. High-grade pipeline products, and applied to many of the world’s major pipeline projects.
