Product Name: Inner and Outer Ring Spiral Woudn metal Gasket Balance: Balanced Type: 316ss Standard: Standard Performance: Temperature Temperature: High Temperature Mechanical Seal Speed: High-Speed Mechanical Seal Pressure: High Pressure Mechanical Seals Structure: Double-End Trademark: chunhuan Transport Package: Plastic Bags and Wooden Boxes Specification: as your request Origin: Zhenjiang HS Code: 39209910 Product Description DEscriptION OF PRODUCTSmetal spiral wound gasket is widely used as a sealing gasket at present.It is the best elastic gasket in semi-metal sealing gasket. It is made of V-shaped or W-shaped thin steel belt and various fillers alternately wound and can withstand The use of high temperature, high pressure and conditions suitable for ultra-low temperature or vacuum conditions can solve the problem of chemical corrosion of various gaskets by changing the material combination of the gasket.The structural density can be made according to the different locking force requirements to strengthen The main body and accurate positioning, winding gasket with metal inner ring and outer ring, using internal and external steel ring to control the maximum compression, the gasket surface contact surface of the flange sealing surface requirements are not high.APPLICATION*Suitable for uneven load, easy relaxation of joint force, periodic change of temperature and pressure, impact or vibration.*Is the valve, pump, heat exchanger, tower, manhole, hand hole and other flange connections of the static seal original,*Widely used in petrochemical, machinery, power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments.FILLED MATERIAL AND MAIN PROPERTIESFillerTemperature(ºC )Max PressureMediaCompression(% )Rebound(% )Relaxation(%)F.G.-220--550250 BARcorrosive18--30≥17≤18ASB-150--450100 BARvulgaris air tightness18--30≥19≤28PTFE-200-- 250100 BARcorrosive18--30≥15≤13NAF-100--350100 BARvulgaris air tightness18--30≥19≤28MICA-150--800100 BARH-TEMP18--30≥19/CER-200--1090100 BARUltra-TEMP18--40≥19/MATERIALS FOR OD AND ID,MAIN PROPERTIESMaterialsMarkHardness(HB)Temperature(°C)Carbon steelCS120-40~+540SUS 304304130~180-195~+550SUS 316L316L130~180-100~+550SUS 321321130~190-195~+760HASTELLOR-B2HASTB215-185~+1090INCONEL-600INC600150-100~+1090MONEL-400MON150-130~+820TiT2215-195~+1090STANDARD·HG20610 /HG20631 / ·ASME B16.20/·DIN / BS 3381-1999·JIS B2404-1999 JIS TS-1998·GB/T4622.2 /·JB/T4719 /SH3407 and so onCHARECTERISTIC1.The applicable working condition range is wide. Can resist high temperature, high pressure, and adapt to the use condition of ultra-low temperature or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of the various media to the gasket can be solved.2.The stress compensation ability is strong. The sealing performance is stable and reliable at the station with frequent temperature and pressure fluctuation.3.The sealing performance is excellent.4.The surface accuracy requirement for flange sealing contact with the gasket is not high. 5.The installation is convenient, and the pre-tightening pressure of the gasket is low.
