Class 1500 Plate Forged Flange  

The connection of SO flange steel structure conforms to the principle of reliable, clear force transmission, simple structure, convenient manufacturing and saving materials. The joint shall have sufficient strength and sufficient air direction suitable for the execution of the joint means. The connection method of the system structure can be divided into weld connection, rivet connection and bolt connection. Weld joint is the main joint of modern structure. Its advantages of simple structure, any form of components can be directly connected; Material economy, does not weaken the section, production and processing is convenient, can realize automatic operation, the connection is closed well, the structural stiffness of its disadvantage is in the weld near the heat-affected zone, the material of the whole phase of the change, resulting in the change of material, residual stress and residual deformation of the compressive member bearing capacity is reduced to crack structure, with crack…
