Spiral wound gasket 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. Item no.

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Metallic Gaskets: \"Metallic Gaskets\" are gaskets that are fabricated from one or a combination of metals to the desired shape and size. Common metallic gaskets are Spiral Wound Gaskets, Double Jacketed Metal Gaskets, Solid Metal Gaskets, Corrugated Metal Gaskets, Ring Type Joint Gasket used for heat exchangers, compressors, condensers, pumps, valves and turbines. These metallic gaskets are suitable for high pressure & temperature applications and require high bolt load to seal. Types: � Spiral Wound, Double Jacketed, Solid Metal gaskets, Corrugated Metal Jacketed Gaskets, Ring type joint Gaskets Non Metallic Gaskets: \"Non Metallic Gaskets\" or \"Soft Gaskets\" are gaskets that are easily compressed under a low bolt load. They are composite sheet materials that are suitable for a wide range of general as well as corrosive chemical applications. They are easily available either in sheet form or as gaskets that are cut accurately to any reasonable shape and size. Non metallic gaskets are usually manufactured from materials like arimid fiber, glass fiber, elastomers, teflon (PTFE), compressed asbestos fibre (CAF), flexible graphite etc. Types are: Non Asbestos, Asbestos, Flexible Graphite, PTFE, Viton, Silicone Rubber, Neoprene and Flange Gaskets.

Spiral wound gasket 1. Structure The wound style gasket consists of "v-shape"(or"w-shape")metal tape and nonmetal tape, which are overlapped each other and wound continuously.To fasten the metal tape, both its start point and end point are tack welded. 2.Performance and features 1. Wide range of applicable working condition, high temperature and high pressure resistance, applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium, through change of composition of gasket. 2.Strong stress compensation, stable and reliable sealing performance even under frequent pressure fluctuation condition. 3.Perfect sealing performance. 4.Normal requirement of flange surface finishing which contact with gasket. 5.Easy installation and low pre-tightening stress of gasket. 3.Kinds of gasket 1.A.Wound style gasket consists of four type:basic type, with inner ring, with outer ring, and with inner and outer rings. B.Heat exchanger wound style gasket:basic type and with inner and outer rings. 2. Normally matrial used: A.Steel tape:08f, 0cr18ni9(304), 0cr18ni9ti, 1cr18ni9ti(321), 0cr17ni12, m02(316), 00cr17ni14m02(316l). B.(cold roll)steel plate for inner and outer ring:outer ring:mild steel, 0cr13 and 0cr18ni9 Inner ring:same as steel tape, special order is a available through negotiation. C.Nonmetal tape:flexible graphite, special made asbestos, teflon and non-asbestos paper. 4.Scope of application 1. Working temperature:-196íµ -700íµ(not higher than 600íµ in oxidic medium) 2.Working pressure:ín25mpa 3.Gasket coefficient:m=2.5-4 4.Min.Pre-tightening specific pressure:y-68mpa 5.Max.Machinable size:-2800mm
