Spiral Wound Gasket is the best in the compression resilient in all the half-metal seal gasket, which is made by the metal hoop band 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 and outer circle 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 handhole. It is widely used in the fields like petrochemical industry, machine, electric power, metallurgy, ship-building, medicine, atomic energe, space navigation. We made spiral wound gasket conform to different standards,for example,ASMI,BS,JIS,DIN and several other criterion used in china.
