Gasket material requirements

Gaskets also have certain requirements for materials. For specific requirements, let the editor of the gasket manufacturer take you to understand together!

(1) Has good elasticity and resilience

(2) It has proper plasticity and can fill the gap of the sealing surface after compression to ensure the sealing.

(3) Mechanical properties such as tensile strength and elongation are good.

(4) Good corrosion resistance, under the action of corrosive media, it will not be damaged, nor will it produce large expansion and contraction

(5) No softening and no creep under high temperature conditions: no hardening and no shrinkage under low temperature conditions.

(6) Good processing performance, easy to obtain and cheap.

Gasket material design needs to be based on industry requirements or known flange standards to determine the adopted standard. Then determine the nominal diameter and nominal pressure of the gasket, which should be the same as the flange. The type of gasket used is determined according to the nominal diameter and the high temperature of the medium. The form of the gasket is determined according to the form of the flange. Determine the gasket material and specify the gasket model according to the temperature, pressure, and corrosion performance of the medium.
