How much do you know about graphite gaskets? Choosing a good graphite gasket not only plays a very important role in industrial pipelines, but also can effectively prevent corrosion. Graphite gaskets must first be made of pure graphite raw materials and pressed. Graphite gaskets are suitable for packing and sealing of various valves, pumps, reaction kettles and other equipment working under high temperature, high pressure and strong corrosive medium.
Secondly, graphite gaskets can be divided into two types according to the material, one is graphite composite gaskets, and the other is flexible graphite gaskets. Graphite composite gasket is punched or cut from reinforced graphite plate, it has good corrosion resistance, high/low temperature resistance, good compression resilience and high strength. Flexible graphite gaskets are punched or cut from shrinking graphite coil or sheet.
Shrinking graphite does not contain binders and fillers, so it has high purity, good corrosion resistance, high/low temperature resistance, good shrinkage resilience and high strength, suitable for sealing low pressure parts, and can avoid graphite and method Galvanic corrosion generated between orchid. Then the graphite gasket has good self-lubrication. Like natural graphite, flexible graphite is easy to slide under the action of external force, so it has smoothness, good wear reduction and small friction coefficient.
The graphite gasket has a high rebound rate. When the shaft or bushing exhibits radial circular runout due to eccentricity in manufacturing and installation, it has sufficient floating performance. Even if the graphite has cracks, it can be well sealed to ensure the fit. It is strict to avoid leakage. Of course, it is also very important to choose a good graphite gasket manufacturer and company!
