The seamless steel tube in the Q345B cold drawn seamless tube is a kind of steel material. It is a low-carbon alloy steel (c<0.2%), with good general performance, good low temperature performance, cold stamping performance, welding performance and machinability. Widely used in bridges, vehicles, ships, equipment, pressure vessels, etc. q represents the surrender of this material. The 345 on the back refers to the surrender value of this material, at the mercy of 345mpa. And as the thickness of the material increases, its yield value decreases.
Cold drawn Q345B seamless pipe is a light-weight, thick-walled steel pipe with a hollow square section, also known as steel refrigerated bending section. Therefore, the Q235 hot-rolled or cold-rolled steel strip or coil is a section steel with a square cross-section size formed by cold bending of the base material and then high-frequency welding. Small-diameter Q345B seamless pipes, except for increased wall thickness, have corner dimensions and edge flatness that reach or exceed the level of resistance welded cold-formed square pipes.
Cold drawn Q345B seamless pipes are used in equipment, machinery production, steel construction projects, shipbuilding, solar power generation brackets, steel layout projects, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, and high-speed Road carving fence, housing equipment, and square tube are similar. Large-caliber Q345B seamless pipes are classified according to the production process: hot-rolled Q345B seamless pipes, cold drawn Q345B seamless pipes, extruded Q345B seamless pipes, and welded square pipes.
Cold drawn seamless pipe is a hollow square cross-section light thick-walled steel pipe. The square pipe is also called steel cold drawn aluminum profile. It uses Q235 hot rolled or cold rolled strip steel or cold rolled coil as the butt weld, which is formed by cold bending, and then is made by high frequency welding machine to make a channel steel with a square cross section. In addition to the thickening of the wall thickness, the corner specifications and edge verticality of Rezart's thick-walled square tube meet or exceed the level of resistance welding machine cold-formed square tube.
