To ensure the sealing performance of asbestos

To ensure the sealing performance of asbestos-free gaskets under high pressure, it is necessary to comprehensively consider the selection of materials, product design, production process and installation and maintenance.

Choose the right material:

Choose materials with good pressure resistance, such as aramid fiber, carbon fiber, nitrile rubber, polytetrafluoroethylene (PTFE), etc., which can maintain stability and tightness under high pressure.

Material formulation optimization:

By adjusting the material formula, the elasticity and flexibility of the gasket are increased, so that it can better adapt to pressure changes and the irregularity of the sealing surface.

Enhanced structure:

The metal skeleton or mesh structure is added to the gasket to enhance the compressive strength and creep resistance of the gasket.

Precise dimensional design:

Select the appropriate gasket size according to the working pressure and temperature to ensure that the gasket can provide enough compression force under high pressure to achieve a good seal.

Production process control:

In the production process, the pressure, temperature and time are strictly controlled to ensure the uniformity and consistency of the gasket.

Surface treatment:

The sealing surface is properly treated, such as grinding, sandblasting, etc., to improve the roughness of the sealing surface and enhance the sealing effect of the gasket.

Preload control:

Ensure that the preload of the connecting parts is appropriate to provide sufficient initial seal pressure.

Installation technology:

Use the correct installation technology to avoid damage or deformation of the gasket during installation.

Regular inspection and maintenance:

Check the wear and aging of the gasket regularly, and replace the damaged gasket in time to maintain the sealing performance.

Stress test:

The gasket is pressure tested before installation to ensure its performance under high pressure meets the requirements.

Use special tools for gaskets:

Use a dedicated gasket installation tool to ensure that the gasket is evenly pressed to avoid local overtightness or overlooseness.

Environmental adaptability:

Considering the temperature, chemical medium and other factors in the working environment, choose the gasket material that ADAPTS to these conditions.

Through the above measures, it can be ensured that the asbestos-free gasket maintains a good sealing performance under high pressure environment, thereby improving the safety and reliability of the equipment.
