Asbestos Gasket Sheet with Wire Mesh Reinforcement for sealing pipelines, flanges, and industrial equipment under high t.....


Asbestos Gasket Sheets with Wire Mesh Insert are manufactured from asbestos fiber rubber reinforced with steel wire mesh. The combination of asbestos and metal reinforcement provides improved strength and sealing performance. These sheets are produced through compound heating and compression molding, forming a dense structure suitable for high-pressure and high-temperature environments. For added resistance, graphite coating can be applied on one or both sides depending on operational needs.

Applications

These gasket sheets are widely used as sealing materials in systems handling water, steam, air, and gas. They are suitable for flange connections in pipelines, boilers, pumps, and industrial equipment operating under varying pressures and temperatures. Common application industries include petrochemical plants, power stations, shipbuilding, and metallurgy.

Packaging

Asbestos Gasket Sheets with Wire Mesh Insert are packed on wooden pallets or in wooden cases, typically weighing 1000–2000 kg per pallet
