The production process of seamless steel pipe for high pressure boiler is more strict than that of A588 Gr B structural steel plate ordinary steel pipe. In the process of using seamless steel pipe for high pressure boiler, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel pipes for high-pressure boilers are higher, and has requirements for good structural stability.
Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. A588 Gr B structural steel plate, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.
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 A588 Gr B structural steel plate 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 A588 Gr B structural steel plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
