Product Name:Basic Type Spiral Wound Gasket
1,good compression elasticity
2, high temperature and pressure resistance
3,Acid and alkali resistance

Spiral wound gasket structure: spiral wound gasket (basic type) is made by superposing, winding and welding V-type or W-type stainless steel tape and non-metallic filing. It is usually wound by stainless steel, 304,304L,316,316L,321,Ta Mon400, Inconel, asbestos (graphite, PTFE, mica, ceramic) tape used for special-purposed equipments.

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. 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.
