Rectangle pipe Q195 Q235 Q345 Q215 Square and rectangular

Short Description:

Rectangular pipe is a kind of hollow square section light thin-walled steel pipe, also known as steel refrigerated bending section. It is a section steel with square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. Except for the increased wall thickness, the corner size and edge flatness of the hot-rolled extra-thick-walled square tube reach or exceed the level of the resistance welded cold-formed square tube. Classification of rectangular pipes: steel pipes are divided into seamless steel pipes and welded steel pipes (seamed pipes) hot-rolled seamless square pipes, cold drawn seamless square pipes, extruded seamless square pipes, and welded square pipes.

    A steel material that is open at both ends and has a hollow and concentric cross-section, The specifications of steel pipes are expressed by external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. The size range is very wide, from small diameter capillary tubes to large round steel pipes with a diameter of several meters. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes.
