Applications
Oil And Gas Industry
Mostly installed in pipelines and valves, in oil and gas industries, a non-metallic gasket is specifically introduced in low temperature and pressure conditions. It enhances sealability and the safety of pipeline supplies.
Chemical Processing Industry
By now, it has been known that a non-metallic gasket remains ineffective during chemical exposures compared to metals; hence, they are quite popular in chemical processing industries.
Power Generation Industry
The power generation industry makes use of many resources, like turbines, natural gases, fossil fuels, generators, etc, to generate power and energy. Hence, there is a requirement for pipeline systems where gases and liquids pass through.
