Appication:
spiral wound gasket is the best in the compression resilient in all the half-

metal seal gasket, which is made by the steel tape and different kinds of

packing material. We can make its structure density according to the demand of

different locking force, and we use the outer ring to control the maximum

compact degree. So it can be well suit the rough flange face, especially suit

the situation of unbalance load, loose of joint force, temperature and pressure

change periodically, concussion and shock. It is used in flange joint of valve,

pump, heat exchanger, tank, and hand hole. It is widely used in the fields like

petrochemical industry, machine, electric power, metallurgy, ship-building,

medicine, atomic energy, space navigation.
