What is S235 straight seam welded pipe?
S235 straight seam welded pipe is a type of low-carbon steel pipe. Its manufacturing process involves rolling steel plates into pipes and then welding a straight seam longitudinally along the pipe body.
How is the straight seam of S235 straight seam welded pipe formed?
The straight seam of S235 straight seam welded pipe is achieved through the following process: rolling steel strips into pipes, and then welding longitudinal joints. The most common welding method is high-frequency welding. In this method, high-frequency current is used to heat the edges of the steel strip to a molten state, and then the edges are pressed together by extrusion rollers to form a continuous straight seam.
What materials are S235 steel pipes made of?
S235 steel pipes are made of low-carbon steel, which contains elements such as carbon, manganese, silicon, phosphorus, and sulfur. This material is chosen because of its good weldability, strength, and cost-effectiveness.
What are the applications of S235 steel?
S235 steel is used in general construction fields, such as building frames, bridges and supporting structures, as well as chassis and suspension components in the automotive industry.
What materials does S235 steel correspond to?
S235 steel corresponds to several other material grades, the most common of which include ASTM A36 and A283 C grades from the United States, St37 from Germany, Q235 from China, and SS400 or SM400A from Japan.
