What are the main causes of gasket leakage? Asbestos - free gasket manufacturers for you to introduce it:

The working conditions of the sealing gasket are very complex, including a wide range of fluid medium, and leakage through the liquid or gas interface, more serious is to cause environmental pollution, product loss, etc., is the most important and difficult task facing the factory, what are the factors of leakage?

1. Material selection

Gaskets are widely used, the required compression load is not the same, such as low-pressure water pump thin flange gaskets, the need for compression load is low, and pressure vessels and pipeline flange gaskets, the need for a large compression load and a good rigid connection structure.

2: medium

Sealing gasket in the whole process of working conditions is not affected by the sealing medium, including high temperature oxidation resistance, chemical corrosion resistance, solvent resistance, permeability resistance, obviously sealing gasket material of chemical corrosion resistance to the medium is the primary condition for the selection of gasket.

3: the temperature

In order to maintain a seal under operating conditions, the maximum or minimum operating temperature and the continuous operating temperature of the gasket should be considered. The difference between the quality of gasket is the creep relaxation property of gasket at a certain temperature. As the temperature increases, the creep becomes more serious.

Four: the pressure

When selecting the maximum pressure, consider the maximum operating temperature that the gasket can withstand. The higher the vapor, the higher the temperature. Rubber gasket can be used in general vacuum; Rubber o-ring and moulded seal strip can be used for higher vacuum. For very high vacuum, special materials of metal gaskets are required.
