Spiral wound gasket structure: spiral sound gasket with inner & outer ring is manufactured by wrapping alternating layers of thin stainless steel and a soft gasket filler material such as graphite or PTFE. Material of inner & outer ring can be carbon steel, SS304, SS316L

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 inner & 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.
