Compensator installed pressure test: 1, the installation before compensation, you should first check bellows expansion joints models, specifications and bearing the pipeline configuration must be complex design requirements. 2, the expansion joint with a lining tube 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 universal pre-deformation 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 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 heat pipe compensator gas medium, when 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 sleeve compensation, 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. Tetrafluoroethane compensation Features (1) the compensation of thermal expansion (2) non-metallic expansion joints can be multi-dimensional direction to provide greater compensation in less size range, the compensation due to piping installation error, the system error is inevitable, nonmetallic compensator can better eliminate installation errors. (3) no reverse thrust due to the main material for the fabric, inability to transfer, non-metallic compensator simplifies design. (4) high-temperature corrosion-resistant fluorine plastics used silicone material with good heat and corrosion-resistant properties. Fortunately, the sealing performance under a variety of media effect, has a good seal. Axial compensator | Compensator | Bo-Rubber (View) by Bo-Rubber Products Co., Ltd. Hengshui.
