Spiral Wound Gaskets

Spiral Wound Gaskets :-

Properties And Application :-

Spiral Wound Gaskets are special semi-metallic gaskets of great resilience, there fore they are very suitable for applications featuring heavy operating conditions. Spiral wound gaskets are manufactured by spirally winding a Vshaped metal strip and a strip of non-metallic filler material. The metal strip holds the filler, providing the gasket with mechanical resistance and resilience.
Spiral Wound Gaskets can be reinforced by an outer centering ring and/or inner retaining ring. The outer centering ring controls the compression and holds the gasket centrally within the bolt circle. The inner retaining ring increases the axial rigidity and resilience of the gasket.

Spiral Wound Gaskets should always be in contact with the flange and should not protrude into the pipe or project from the flange. Spiral wound gaskets can be used for sealing flange joints, manhole and handhold covers, tube covers, boilers, heat exchangers, pressure vessels, pumps, compressors and valves; in industries such as petrochemical, pharmaceutical, shipbuilding, and food processing, in power industries and nuclear power stations. They are ideal for steam, oil, liquids, gases, acids, alkalines, various organic mediums and solvents.
ADVANTAGES of Spiral Wound Gaskets

• Sealing under heavy operating conditions.
• Strong stress compensation, stable and reliable sealing performance even
• Under frequent pressure fluctuation condition.
-Solid construction provides stability and seallability even when the sealing surfaces
• Are slightly corroded or bent. - Easy installation.

SHAPE AND CONSTRUCTION OF SPIRAL WOUND GASKETS
Spiral Wound Gaskets are produced in several styles and combination of materials to fit the most stringent application. Spiral wound gaskets are usually of circular shape, however we can produce them in other shapes such as: oval, rectangular, with round corners, etc. Our standard production program comprises a range of spiral wound gaskets with inner diameters of 10 mm to 3000 mm and a nominal thickness of 3.2 mm, 4.5 mm and 6.5 mm. Spiral wound gaskets of non-standard dimensions and shapes, and larger diameters are available on request.

Gasket standard styles: - Gaskets without guide and inner ring - Gaskets without guide and inner ring - Type S - Gaskets with inner ring – ASP-CI - Gaskets with guide (outer) – ASP-CG - Gaskets with guide and with inner – ASP-CGI
