For suggestions on gasket material characteristics and gasket selection criteria, please follow the editor of Metal gasket Wholesale Price for a simple understanding!
1. High-risk occasions need to achieve good sealing, safe and non-hazardous. High-risk situations include high temperature, high pressure, steam, etc. Gaskets should be selected from metal ring gaskets with excellent performance, tooth-shaped composite gaskets, spiral-wound gaskets, wave-tooth composite gaskets, etc. Spiral wound gaskets are guaranteed to have inner and outer reinforcement rings. Corrugated composite gaskets can be used as a preferred product because of its better overall performance and moderate price. Tooth-shaped pads and metal flat pads are used when the working conditions do not change. The metal ring gasket is affected by the manufacturing cost, etc., and should be avoided if it is not ideal after application.

2. Asbestos-containing sealing materials should be used less or not, because this type of material can generally only be used for low-parameter working conditions of unimportant occasions such as ordinary water, gas and oil. Graphite pads can be used to replace asbestos rubber sheets in low-parameter situations. Although it is expensive but has good performance, it is a common substitute material for asbestos rubber sheet at present.
3. For pressure and temperature changes, vibrations and impacts, spiral wound gaskets and corrugated composite gaskets with good resilience performance should be used.
4. The heat medium heating system uses graphite composite pads, etc., and try not to use asbestos rubber sheets as seals. Graphite that does not swell and expand and has strong media permeability should be used as the main spiral wound gasket, corrugated composite gasket, etc.
5. For general corrosive media, spiral wound gaskets and corrugated composite gaskets with stainless steel frame can be used. Flat gaskets and PTFE-coated gaskets are used for strong corrosive conditions. Low-pressure low-temperature graphite composite mat.
The above is the introduction of the editor of Metal gasket Wholesale Price: tips on the characteristics of gasket materials and related recommendations for gasket selection criteria.
