Hydraulic Seal Installation Requirements:
1. The sealing surface of hydraulic seal gasket and flange should be clean.
2. The outer diameter of the hydraulic seal gasket should be smaller than the flange sealing surface, and the inner diameter should be slightly larger than the pipe inner diameter.
3. The pretension of the gasket shall not exceed the design requirements.
4. Torque wrenches are best used when packing asbestos gaskets.
5. When installing the gasket, tighten the nuts one by one.
6. In case of leakage, step-down treatment must be carried out after installation, and the sealing gasket must be replaced or adjusted.
