Compensator: the compensator habits also called expansion joints, or expansion joints. Constituting the main body of the work by the bellows (an elastic element) and the end of the tube, brackets, flanges, conduits and the like accessories. Is a form of compensation components. Axial body with its work effectively stretching deformation of the bellows sleeve compensator to absorb pipelines, conduits, containers, etc. Dimensional changes caused by thermal expansion and contraction and other reasons arising from, or compensation lines, conduits, containers, etc., and lateral angular displacement. Can also be used for noise damping. Widely used in modern industry. Compensator installed pressure test: 1, before installation, you should first check the bellows expansion joints models, specs and pipe holder must complex design requirements. 2, the expansion joint axis compensator with lined barrel, should pay attention to the consensus (according to mark the installation of expansion joints flow) direction cylinder lined with medium flow direction. Expansion Joints plane angle to rotate the screen hinge should be consistent with the displacement plane. 3, piping should be removed immediately after installation auxiliary positioning mechanism and fasteners for installation on the expansion joint transport protection, according to the design requirements for the position will be transferred to the specified limit device, so that piping in environmental conditions can be fully make up. 4, in addition to the design requirements for pre-tension and compression, or "cold tight" outside the pre-deformation non-metallic compensation, prohibited the use of bellows deformation method to adjust the pipe misalignment, to avoid affecting the normal function of the expansion joint, otherwise it will reduce its life and increasing the load piping, equipment and support structure. 5, expansion joints all active components shall be stuck or limit the external component parts of their activities normally. 6, the installation process does not allow welding slag splashing into the group bellows and bellows surface by other mechanical damage. 7, expansion joints and connecting pipes for gas medium, when the hydraulic test, to consider the need for additional expansion joint takeover falsework when filled with water in order to load. 8, hydrostatic test water must be pure, non-corrosive, and control the content of chloride ions in the water does not exceed 25ppm. After the pressure test, should be drained of water as soon as bellows, and quickly dry the shell inner surface waves. 9, it should be noted that the expansion joint is not absorbed torque, so when installing expansion joints, expansion joints are not allowed by the reverse. 10, all active components expansion joints shall not be stuck or limit the external component parts of the normal operation of their activities. 11, the insulation should be done outside the expansion joint protection sleeve, do not directly on the bellows. Shall not use chlorine insulation materials. 12, expansion joints allow no more than 1.5 times the nominal system pressure test. Bad.
