Why is the weld seam of S235jrh SSAW welded steel pipe spiral?
S235jrh SSAW welded steel pipe is due to the use of spiral submerged arc welding (SSAW), a manufacturing process used to weld narrow steel strips into large-diameter steel pipes.
What is the main difference between S235jrh SSAW welded steel pipe and straight seam welded steel pipe (LSAW)?
What are the main advantages of S235JRH SSAW welded steel pipe?
S235JRH SSAW welded steel pipe include: the ability to manufacture large-diameter steel pipes, high strength, good durability, high cost-effectiveness, and wide range of applications. Furthermore, the submerged arc welding process also offers many advantages, such as stable quality, fast production speed, smooth inner surface, and low electrical resistance.
What engineering projects are S235JRH SSAW welded steel pipes typically used in?
S235JRH SSAW welded steel pipes are primarily used in civil engineering and construction, particularly in structural applications such as bridges and building frames. They are also widely used in the petrochemical, energy, and general manufacturing industries, for projects such as water supply and sewage treatment systems, structural supports, and pile foundations.
Why are S235JRH SSAW welded steel pipes suitable for manufacturing large-diameter steel pipes?
S235JRH SSAW welded steel pipes are suitable for manufacturing large-diameter steel pipes because the spiral submerged arc welding process allows for continuous production using narrower steel strips, enabling the manufacture of large-diameter steel pipes that are not limited by the width of the steel plate. Compared to other large-diameter steel pipe manufacturing methods, this process also offers higher dimensional accuracy, more stable strength, and lower costs.
