plate S690QL quality and thickness range

How to choose the material and specification of plate S690QL, boiler tube? First, select the specification according to the actual use. Secondly, material: the suitable boiler tube material is different for different use scenarios. Thirdly, the wall thickness of the boiler tube should be strictly in accordance with the relevant standards. If the thickness is not up to standard, it is easy to cause accidents, so it must be strictly controlled. Finally, the boiler tube should be checked in time when receiving the goods, and the relevant instruments should be used to detect whether the steel quality has reached the standard, if not, it can be rejected.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the plate S690QL steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of plate S690QL extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
