What are the properties of S355J2H material?
S355J2H is a hot-rolled structural hollow profile widely used in construction and engineering. It is made of non-alloy fine-grained steel with a minimum yield strength of 355 N/mm². The "S" in the name represents structural steel, and "355" represents the material's minimum yield strength.
What is S355J2H submerged arc spiral welded pipe?
S355J2H submerged arc spiral welded pipe is a structural steel pipe made of S355J2H steel, produced by continuously welding steel strips into a spiral shape using submerged arc welding.
What is the production process of S355J2H submerged arc spiral welded pipe?
The production process of S355J2H submerged arc spiral welded pipe involves first unfolding the steel strip, then precisely shaping it, and finally spiral welding it using internal and external submerged arc welding processes.
In which fields is S355J2H submerged arc spiral welded pipe mainly used?
S355J2H submerged arc spiral welded pipe has a wide range of applications, including transportation in the oil and gas industry, water supply and drainage in water conservancy projects, and urban pipelines in municipal engineering. It is also used in building structures such as foundations and bridges, as well as power systems.
What are the advantages of S355J2H submerged arc spiral welded pipe compared to other steel pipes?
Compared to other steel pipes (especially straight seam steel pipes), S355J2H submerged arc spiral welded pipe has advantages in strength, production flexibility, and efficiency. Its main advantages include the spiral weld seam's ability to more evenly distribute stress, allowing for the production of large-diameter steel pipes, and reducing costs through flexible raw material usage.
