Detailed Introduction to the Functional Characteristics of Graphite Composite Gaskets
Graphite composite gaskets are gaskets composed of punched metal tooth plates or metal mesh plates combined with expanded graphite particles. They are generally made by stamping or cutting improved graphite plates using professional gasket cutting equipment. Commonly used inner layer improvement materials for improving graphite gaskets include ss304, ss316, tinplate, etc., with thicknesses ranging from 0.05 to 0.2mm. Methods include punch plate-enhanced composite gaskets, mesh plate-enhanced composite gaskets, and flat plate-enhanced composite gaskets.
Functional Characteristics of Graphite Composite Gaskets: Modified graphite composite gaskets exhibit excellent corrosion resistance, high/low temperature resistance, radiation resistance, superior compressive elasticity, and high toughness. The required preload is less than that of metal gaskets and basic metal spiral wound gaskets, and the requirements for flange surfaces are not high. They are more cost-effective gaskets.
When the edge wrapping method is used, it can maintain the excellent functions of the original graphite composite gasket, facilitate easy installation and disassembly of equipment, and are not easily damaged. It can also prevent corrosion of the gasket by materials and oxygen in the external air, improving temperature and pressure resistance. Structural Types of Modified Graphite Composite Gaskets: Graphite composite gaskets come in RF, MFM, and TG types, suitable for flanges with raised faces, male and female faces, and tongue and groove faces.
Depending on requirements, RF-type gaskets can be wrapped with stainless steel or carbon steel, known as RF-E type. Application Scope of Modified Graphite Composite Gaskets: Graphite composite gaskets are mainly used in sealing positions at flange connections of various pipelines, valves, pumps, pressure vessels, heat exchangers, coolers, generators, gas compressors, exhaust pipes, refrigerators, etc. They can replace asbestos rubber gaskets and iron-clad gaskets.
Special Specifications of Graphite Composite Gaskets:
Graphite composite gaskets, also known as enhanced graphite gaskets or high-strength graphite composite gaskets, are gaskets composed of punched metal tooth plates or metal mesh plates combined with expanded graphite particles. Professional gasket cutting equipment is usually used to improve the stamping or cutting of graphite plates. Commonly used inner layer improvement materials for graphite gaskets include ss304, ss316, or tinplate. They can be made with thicknesses ranging from 0.05 to 0.2mm, including punch plate-enhanced composite gaskets, mesh plate-enhanced composite gaskets, and flat plate-enhanced composite gaskets. Graphite composite gaskets can be made into various circular and geometrically complex shapes, such as water level gauge gaskets, cylinder gaskets, exhaust pipe gaskets, and heat exchangers with ribs.
