To ensure the sealing of the valve piping system, in addition to selecting suitable sealing materials, it is also necessary to install the gasket in the following correct manner:
The gasket must be placed in the center of the flange, which is especially important for shoulder flanges; to ensure the flatness and processing accuracy of the sealing surface; the connecting bolts must be evenly and symmetrically tightened; the use of metal washers must ensure that the load is uniform and tight Use a torque wrench when bolting; check and re-calibrate the torque of the connecting bolt after the valve piping system runs for one cycle; to ensure the service life of the gasket, please do not use liquid or metal matrix anti-sticking agents or lubricants.
