First, the raw materials: Expandable graphite (flexible graphite) is chemically treated with pure natural graphite and treated at a high temperature of 1000 ° C. This material provides excellent heat resistance and chemical resistance, and it can make the gasket highly elastic and low ductility. feature. Second, the characteristics: 1. The sealing performance remains almost unchanged in the high temperature range from extremely low temperature to 400 °C. 2. Excellent chemical resistance for almost all liquids (except strong oxidizing acid, etc.) 3. Due to the cold deformation and ductility, the installation is too tight and has no effect on the gasket. Third, type: Flexible graphite gaskets are cut from flexible graphite sheets (or with metal reinforcement) and are divided into four types depending on the application: 1, T / # 1200 flexible graphite gasket: cut from flexible graphite sheet, used for pipe flanges and bonnets. It is recommended that these gaskets be small diameter gaskets depending on their low mechanical strength. 2. T/#1210 flexible graphite gasket MI: The hooked carbon steel sheet (0.2 mm thick) is sandwiched between flexible graphite sheets and then cut into specific dimensions with high mechanical strength. 3, T / # 1215 flexible graphite gasket PM: flexible graphite sheet is adhered to both sides of a 0.2 mm thick 304 stainless steel sheet, has high mechanical strength and is easy to transport, because it can also be cut into complex shapes, Such gaskets are widely used in various industries. 4. T/# 1215-a flexible graphite gasket PM-a: Replace the stainless steel sheet in T/#1215 with 316 steel (50 microns). Fourth, the application: It is used in various industrial pipe flanges, heat exchangers, bonnets, etc., as well as special shape flanges on liquid level gauges and level gauges.
