Silicon Carbide Inserts is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects. Silicon Carbide Inserts is made of metal rubber, which is a homogeneous elastic porous material, which not only has the elasticity of rubber, but also has the excellent characteristics of metal, and can work at a temperature of -150~800 °C. At the same time, it can also bear pressure, and has the dual functions of pressure bearing and sealing within a certain range. Its uses mainly include the following:

1. FRP pipes; FRP sand pipes; FRP jacking pipes; cable protection pipes; flue gas desulfurization pipes; coal mine gas drainage pipes; power plant desulfurization and dust removal pipes;

2. Municipal water supply and drainage pipes are sealed;

3. Various process pipeline sealing (petroleum, chemical industry, metallurgy, papermaking, sewage, seawater desalination, food brewing and beverage processing, medicine, etc.);

4. Sealing of sewage collection and transportation pipelines and reclaimed water pipelines;

5. Sealing of drinking water transmission trunk pipes and water distribution pipes;

6. Oilfield water injection pipe sealing;

7. Hot water delivery pipes and hot spring water delivery pipes are sealed.
