Graphite gaskets are made by cutting or stamping pure graphite plates or metal (tooth plates, flat plates, mesh) reinforced graphite plates, and have numerous sealing properties, such as thermal stability, self-lubricating, corrosion resistance, anti-aging, non brittleness, etc. They can be used stably for a long time under harsh working conditions with minimal maintenance. The lining material can be selected from different metal sheets. The types available are no edge wrapping, inner edge wrapping, outer edge wrapping, and inner and outer edge wrapping. Graphite cutting gaskets are made by punching or cutting pure graphite plates. They have good corrosion resistance, high/low temperature resistance, good compression resilience, and high strength. Various circular and complex geometric gaskets are widely used in pipelines, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc.

Graphite gaskets belong to the sealing gasket series.

Classification
Flexible graphite gaskets are cut from flexible graphite sheets (or with metal reinforcement) and are divided into four types according to application needs:

1. Flexible graphite gasket: cut from flexible graphite sheets, used for pipeline flanges and valve covers, etc. It is recommended that these gaskets be small diameter gaskets, depending on their low mechanical strength.

2. Flexible graphite gasket MI: A hooked carbon steel sheet (0.2 mm thick) is sandwiched between flexible graphite sheets and then cut into specific sizes, with high mechanical strength.

3. Flexible graphite gasket PM: The flexible graphite sheet is adhered to both sides of a 0.2mm thick 304 stainless steel sheet, which has high mechanical strength and is easy to transport. Due to its ability to be cut into complex shapes, this gasket is widely used in various industries.

4. Flexible graphite gasket PM-A: Replace the stainless steel sheet in T/# 1215 with 316 steel (50 microns).

application
Used for various industrial pipeline flanges, heat exchangers, valve covers, as well as special shaped flanges on liquid level gauges and level gauges.

The graphite gasket is made of graphite wire and is woven and shaped. Graphite gaskets are suitable for sealing the packing boxes of various valves, pumps, reaction vessels, and other equipment working in high temperature, high pressure, and highly corrosive media.

raw material
Expandable graphite (flexible graphite) is made by chemically treating graphite and subjecting it to high temperature treatment at 1000 ℃. This material provides excellent heat resistance and chemical resistance, which can make the gasket have high elasticity and low ductility characteristics.

feature
1. The sealing performance of flexible graphite gaskets remains almost unchanged in the range of extremely low temperature to 400 ℃;

2. Flexible graphite gaskets have chemical resistance to almost all liquids (except for strong oxidizing acids);

3. Due to its low cold deformation and ductility, installing it too tightly has no effect on the flexible graphite gasket
