The dismantling joint is composed of body, sealing ring, extension tube and other main components. It is suitable for the pipe connected with the flange on both sides. During installation, adjust the installation length between the two ends of the product and the flange, and evenly tighten the gland bolt diagonally to make it into a whole and have a certain displacement. It is convenient to adjust according to the field size during installation and maintenance. When working, the anti-axial thrust can be transmitted to the entire pipeline. It is made by adding flange short pipe and force transmission screw on the basis of flange loose sleeve compensation joint, the subtype compensation joint differs from the loose sleeve compensation joint and the loose sleeve limit compensation joint in that the compensation amount refers to the adjustment amount during installation and disassembly. Once all of the nuts are tightened, as it is rigid connection, it can pass axis force, so as to protect the valve, pump and other equipment.
