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.
Description: WFY RJ3300is machined from solid metal in a variety of shapes and designed for high pressure, high temperature or highly corrosive applications by selecting the most suitable material and shape. It is designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses.
Description: WFY CAFare made from selected asbestos fibre, natural rubber, filling material and dye. A price worthy quality of dependable performance, plus adaptability to many sealing requirements makes this jointing the most economical sheet packing choice in the wide range of industrial fields.

Specification:
Description: WFY PTFE product includes sheet. They are molded, skived or cut from 100% virgin PTFE. It has the best chemical corrosion resistance among known plastics. Without being aging, lowest friction coefficient, wear resistance. The unloaded operating temperature range is -180~+260C.
WFY-6100 A is a packing with A grade of quality, the yarn with good tensile strength, and excellent thermal conductivity.
WFY-6100 B is economical gPTFE packing, braided from normal graphite PTFE yarn.
Application:
For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings. Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. It is also against water, steam, petroleum derivatives, vegetable oil and solvents.
