What is a graphite composite gasket? Baofang Sealing's high-strength graphite composite gaskets are made by cutting or stamping pure graphite sheets or metal (toothed sheets, flat sheets, mesh) and possess many excellent sealing properties such as thermal stability, self-lubrication, corrosion resistance, no aging, and no brittleness. They can be used stably for a long time under strict operating conditions and require little maintenance.
High-strength graphite gaskets can be processed into the following types according to application requirements: solid graphite composite gaskets, inner graphite composite gaskets, outer graphite composite gaskets, and inner-outer graphite composite gaskets. The packaging method for graphite composite gaskets is designed to retain the excellent properties of the original gasket, making it easy to install and disassemble, difficult to damage, and also able to prevent corrosion of the gasket and improve pressure resistance. 304 or 316 stainless steel are common edging materials.
Non-metallic sealing gaskets (graphite gaskets) are cut from flexible graphite sheets (or containing metal reinforcement) and are divided into four types according to application requirements: flexible graphite gaskets for pipeline flanges, valve covers, etc. It is recommended that these gaskets be small in diameter due to their low impact toughness. Flexible graphite gaskets with carbon steel hooks (0.2mm thick) sandwiched in the center of the flexible graphite sheet are then cut to specific dimensions and have very high impact toughness. Flexible graphite gaskets PM: flexible graphite sheets adhered to both sides of 0.2mm thick 304 stainless steel sheets have high impact toughness and are convenient for transportation. They can also be cut into complex shapes and are widely used in various industries. Applications: used for various industrial pipeline flanges, heat exchangers, valve covers, as well as unique shaped flanges in liquidometers and levels.
High-strength graphite composite gaskets can be made into graphite composite gaskets with stainless steel edges according to needs. Several methods are as follows: solid graphite composite gaskets with inner edge wrapping, solid graphite composite gaskets with outer edge wrapping, and solid graphite composite gaskets with both inner and outer edge wrapping. The common edge materials for graphite composite gaskets are 304 or 316L stainless steel. Functional characteristics: they have good corrosion resistance, high/low temperature resistance, radiation resistance, good compressive elasticity, and high toughness.
Graphite metal spiral wound gaskets have a preload force less than that of metal gaskets and metal spiral wound gaskets, and have low requirements for flange surfaces. They are cost-effective gaskets. If the edging method is used, it can retain the excellent functions of the original graphite composite gasket, make installation and disassembly convenient, be difficult to damage, and also prevent erosion of the gasket by substances and oxygen in the external air, improving temperature and pressure resistance.
