The Asbestos Material:Asbestos occurs naturally in the environment and is actually a group of minerals. Because of its resistance to heat and corrosion, asbestos was used extensively in the manufacturing industry--especially in the building and automotive trades--until its health hazards were discovered. Gaskets make a joint--or two matching machine parts--tight, preventing the leakage of gas or fluid.
Description:Asbestos gasket can be used for most medium specification applications.It can be used for sealing against steam,air, gases, water, oils, hydraulics and non-aggressive media. This kind of gasket can also be used for high pressures.Sometimes,we can insert some reinforced material.Such as graphie,metal wire,tanged sheet.
In fact,this asbestos gasket are compressd with rubber material to be a sheet.The sealing property is partly based on the rubber material.
NBR - good for oils, gas, mild chemicals and water
SBR - good for saturated Steam, mild chemicals inert gas and water
Neoprene - good for saturated steam, refrigerants, oils, fuels, mild acids and alkalies and water.
EPDM - good for saturated steam, mild chemicals and water
Different grade of asbestos gaskets are including:
Low Pressure Asbestos Gasket(ZD-G1331):It is made from white chrysotile fibre.It is suitable for the sealing condition of most low temperature and low pressure.It is used to seal steam,water power,gas plant,oil and other neutral medium.
Medium Pressure Asbestos Gasket(ZD-G1332):It is used to seal steam,water power,gas plant,oil and other neutral medium.
