Product Description

  Spiral wound gasket  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.
Equipment: It is used as static sealing material for pipeline, valve, pump, pressure vessel, condenser, tower, manhole and hand hole's flange connection parts;
Industry: It can be used in petrifaction, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy, space navigation and so on.
Medium: It is suitable for high-temperature, high-pressure steam, oil, gas, solvent, hot oil and so on. 

  Spiral Wound Gasket is made by thin metallic strip and different sort of filler materials, which is used to control the compression. It also can be accompanied with an inner ring, an outer ring and inner and outer rings when required. It combines the advantages of high elasticity and strength of metallic strip and flexibility of fillers. Furthermore, it well suits the rough flange face, especially is suitable for the situation which is prone to stress relaxation like impact vibration and the circumstance with frequent change in pressure and temperature. We provide spiral wound gasket conform to different standards, but can also produce non-standard, special-shaped, and large metallic spiral wound gasket for some special requirements.
