GB/T3091 Spiral Steel Pipe
GB/T 3091-2008 is the national standard for "Welded Steel Pipes for Low-Pressure Fluid Transportation". This standard specifies the size, shape, weight, and Technical requirements, test methods, inspection rules, packaging, marking and quality certificates, etc.
GB/T3091 double-sided submerged arc spiral steel pipe has a wide range of uses, including construction, machinery manufacturing, steel structures and other fields. Because of its good mechanical properties and wear resistance, it is widely used in pipelines transporting oil, natural gas and other fluid materials. At the same time, the steel pipe is also widely used in construction projects such as bridges, tunnels, and highways, as well as in the manufacturing of industrial equipment such as chemical industry, electric power, and metallurgy.
