The safest and most stable way to remove hydraulic transition joints

Oct 20,2022 / BY DEVELOPERS
There are steps to remove the flange gasket:
(1) Open the bypass valve, close the international trade valves on both sides of the dismantling valve in turn, open the automatic exhaust valve for the upper and lower flow valves, pour the discharged aqueous solution into the dirty gas tank, and confirm that the pressure relief is successful.
(2) Use an adjustable wrench to unscrew the flange bolts (when removing the four flange bolts, remove the one that solves your problem at first, and the ferrule type joint factory does not need to remove the other three bolts, and then use a crowbar for correction; Use a spudger to pry out the flange, then remove it with a scraper to remove the 2 flange surfaces of the old gasket.

(3) Select a suitable gasket, spread a layer of vegetable butter on both sides evenly, and pad the gasket on the protruding surface in the middle of the two flanges. Align the two ends of the center, install the bolt, then tighten the nut, and tighten the nut several times evenly and at a strong angle. It is recommended that the bolt extend 2 to 3 pitches from the nut.
(4) After installing the flange gasket, it should pass the work stability test and there is no leakage. Then open the water inlet valve and the precipitation valve. The ferrule type joint manufacturer closes the inlet valve channel gate, and then encapsulates the tool and removes it. on site.
Difficulties in removing flange gaskets:
(1) Air circulation is carried out during the operation period in the house to prevent the effluent of natural gas from appearing and causing poisoning under working conditions.
(2) The safety and safety operation procedures of quick hydraulic joints should conform to the safe and civilized operation process. The application of emergency shut-off valves should be stable. The workers should sleep on their sides and stand up. When playing props, they should be handled with care to prevent flames from being hit and collided; after the operation process is completed, work should be carried out to eliminate raw materials and eliminate the scene.
