Gasket Sheets For gas
When selecting gasket sheets for sealing applications involving gases, it’s essential to choose materials that offer excellent gas-tight sealing properties, resistance to compression set, and compatibility with the specific gas or gases being sealed. Here are some gasket sheet options commonly used for gas sealing applications:
Graphite Sheets:
- Graphite gasket sheets are widely used for sealing applications involving gases due to their excellent compressibility, resilience, and gas-tight sealing properties. Graphite offers high-temperature resistance and chemical compatibility with a wide range of gases, making it suitable for use in flange connections, heat exchangers, and high-pressure gas systems.
PTFE (Polytetrafluoroethylene) Sheets:
- PTFE gasket sheets offer exceptional chemical resistance and low permeability to gases, making them suitable for sealing applications where gas-tight seals are required. PTFE is inert and non-reactive with most gases, ensuring reliable sealing performance in high-pressure gas systems, vacuum systems, and cryogenic applications.
Metal Sheets:
- Metal gasket sheets made from materials such as stainless steel, copper, or aluminum can provide effective gas sealing in high-pressure and high-temperature applications. Metal gaskets offer excellent resilience, stability, and resistance to compression set, making them suitable for use in flange connections, pressure vessels, and piping systems handling gases.
Non-Asbestos Fiber Sheets:
- Non-asbestos fiber gasket sheets, particularly those reinforced with aramid fibers or synthetic elastomers, can provide reliable gas sealing performance in moderate-pressure and temperature applications. These gasket sheets offer good compressibility, resilience, and resistance to blowout, making them suitable for use in gas distribution systems, compressors, and industrial equipment.
Rubber Sheets:
- Certain rubber gasket materials, such as silicone or fluoroelastomers (e.g., Viton®), offer good gas sealing properties and chemical resistance in specific gas applications. Silicone rubber sheets provide excellent flexibility and temperature resistance, while fluoroelastomer sheets offer enhanced chemical resistance and gas-tight sealing performance.
When selecting gasket sheets for gas sealing applications, it’s crucial to consider factors such as the type of gas, operating pressure and temperature, flange surface finish, and assembly torque. Proper material selection and gasket design are essential to ensure reliable and long-lasting gas-tight seals in various industrial and commercial applications.
