By applying modern technologies and innovative ideas, we are able to manufacture and export a large collection of Spiral Wound Gaskets. These gaskets are known to tolerate temperature fluctuations, high pressure and temperature differences. All these products are made with the capacity to maintain the firm seal under uneven and variable loading. Known for their high strength and appropriate dimensions, the range of Spiral Wound Gaskets is highly demanded diverse sealing applications.
A requirement of any gasket is the ability to recover under variable loads. The effects of pressure and temperature fluctuations, the temperature difference across the flange face, together with flange rotation, bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal under variable and uneven loading. The spiral wound gasket, meets these requirements.
A spiral wound gasket is manufactured by spirally winding a preformed metal strip and filler on the outer periphery of metal winding mandrels. The winding mandrel outside diameter forms the inner diameter of the gasket and the laminations are continually wound until the required outer diameter is attained. Normal practice is to reinforce the inner and outer diameters with several piles of metal with no sort fillers being introduced. Our method of manufacturing includes custom designed devices which provide control of gasket density that permit compression to the operating thickness under a specified load, this engineered product is thus "tailor made" to be compatible with the flanged closure in which it is to be used.
The winding material (Hoop) could be Stainless Steel, Monel, Titanium etc. with options of filler materials as CAF, Non asbestos jointing,PTFE, Flexible Graphite, ceramic etc.as per your application.
