1, gasket and flange sealing surface should be cleaned, shall not have any impact on the sealing performance of scratches, spots and other defects.
2. The diameter of the gasket is smaller than the diameter of the flange sealing surface. The inner diameter of the gasket should be slightly larger than the inner diameter of the pipe. The two diameters are different from the general gasket thickness to ensure that the gasket is compressed and less than the inner edge of a container or pipe. In order to prevent the fluid flow in the container or pipe.
3. The pre-tightening force of the gasket should not exceed the design requirements, so as to avoid excessive compression and loss of elasticity of the gasket.
4. When the pad is pressed, use a torque wrench. For large bolts and high-strength bolts, hydraulic fastening devices are used. The tightening torque shall be calculated according to the gasket compression, and the hydraulic pressure of the hydraulic tightening device shall be determined according to the calculation.
5. When installing the gasket, tighten the nuts in the order of the right. But it should not be screwed once the design value is reached. In general, the gasket should be distributed at least 2 to 3 times to make the gasket evenly distributed.
6. For flammable and explosive medium pressure containers and pipelines, safety tools should be used when replacing gaskets to avoid collisions or sparks between tools and flange bolts, causing fire or explosion accidents.
7. If there is a leak in the pipeline, depressurize, then replace or adjust the installation gasket, and operate without pressure.
