Gongyi City Hing Fat plant products are waterproof casing, flanges, rubber joints, duckbill valves, expansion joints, power transmission connectors. Gongyi City Hing Fat equipment company always adhere to the "customer first, quality first" principle, willing to similar products in better prices, more superior quality, to provide customers with perfect service. Flexible joint for steel pipes can be welded connection between the role of compensation from the connectors are widely used in mining, power plants, sewage treatment and other fields, as well as having omitted compensator flange connection of new low-cost, and because of their special design pressure, under certain conditions, under pressure, the pressure and the sealing effect is linear proportional relationship with the compensator expansion joints and other traditional connectors, compared with which it can not be achieved, and without flange connection, easy installation, just two welding to complete, a line can be an even multiple instead of flanges, bring convenience for the construction and greatly reduce waste, breaking the traditional thick, heavy, stupid monopoly of expansion joints, and quickly became pipeline Connection of new ways. Installation Methods a. Welded joints before installation, the first end of the tube welded to the pipe ends, the practice is: Remove the bolts, the clamp open, the end of the tube in accordance with the technical parameters corresponding to the length of the pipe installation point fixed, adjust the tube ends Parallelism after welding. b. mounting bolts apron and side pipes installed in accordance with the above method, after cooling, the seal mounted on both ends of the pipe as shown middle. Practices are as follows: first apron flip, coming inside sealed surface turn out, then wear to either end of the tube, adjusted to the appropriate location, and then pull the outer edge of the apron, the cover was on the other end of the tube, adjust seal on the tube at both ends should be positioned in the seal ring in the middle of the two end pipes. To facilitate a smooth installation apron apron edges can try to turn up and smear Vaseline lubrication. Then clamp buckle in the end the split tube, bolt the wild card is fixed, should be noted: the fastening bolts on the angle method applied gradually alternately, fastening bolts, while the application hammer percussion wild card, so can make the seal coating evenly, can avoid the wild card interface on the ring squeeze abnormal phenomenon. Should be removed after completion of welding or repair the sealing surface of burrs, bumps, scratches and dirt, then spray anti-rust paint. c. Installing wild card wild card finally coated rubber seals, the seal is completely embedded in the wild card sealed room, followed by bolts (must be pressed in order to avoid excessive pressure seals unilateral damage), After installation, water pressure test. d. ACCIDENTAL RELEASE 1. Loosen the bolts were then pressed, the process is available in the hammer position can be corrected Foreign .2 Method 1 Remove the outer case of an invalid card, check the seal ring is broken during the installation process, you can replace the seals to resolve .3 above methods are ineffective treatment can contact the manufacturer for guidance.
