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 Spiral wound gasket is the ideal gasket in the semi-metallic category. A narrow strip of v-shap metal hoop is spirally wound under tension with a filler cushion between the lami nation of the metal and is spot-welded at both ends. This unique construction of a spring-like metal and soft filler provides gasket excel-lent characteristics. Resistance to high temperature and high pressures. Great resilience which allows the gasket to adjust automatically to change in operating conditions, such as pressure and thermal shocks, vibrations etc. Excellent sealability is maintained with comparatively small gasket area. Good tolerance for flange surface finish irregularities. Can be designed to any dimensions economically in circular or moderately noncircular shape. Available in a variety of hoop metals and filler materials to satisfy specific operating conditions.
Portable Manual Refrigerator soft PVC plastic Door Gasket Welding Machine The manual refrigerator door gasket welding machine has feature of: (1) Light weight: total weight just 15kg, so it is convenient to take any place, it is the good choice for gasket repair company. (2) Easy operation, just 4 steps to finish a gasket. (3) Fast welding,welding period 11-14s (4) Heating temperature can adjusted, and also easy to chance mould. (5) The main point: eclomical price for all company.
CORRUGATED METAL GASKET COVERED WITH GRAPHITE OR PTFE LAYER Corrugated metal gasket (CMG) consists of a metal core with concentric grooves on both sides and coated with expanded graphite, PTFE layer or non-asbestos plate. Corrugated metal gasket with soft layer on both sides is used for low pressure applications in large diameter flue gas ducts at high temperature. In addition, corrugated metal gasket is a versatile sealing element when bolt loads are low.Unlike other materials and structures, it can be very resilient. What's more, corrugated metal gasket directly replaces spiral wound gasket and eliminates inward buckling issues while creating a seal at moderate flange stresses.

Specification: Description:WFY SW3100 Spiral-Wound gasket is formed of V-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its end and beginning by dot welded. Depend on its excellent compression resilience it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy, shipbuilding, medical and pharmaceutical nuclear power station and navigation, etc. Application: We can produce according to ASME, BS, JIS and EN(DIN) standards or client request.
