Spiral Wound Gasket manufactured by Wealson is widely used for sealing flange joints, manhole and handhole 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. It can be manufactured with any material as per customers requirement in accordance with the standard ASME, DIN, BS, API or to customer’s specification.
Shape and Construction
Spiral wound gaskets are produced in several style 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 10mm to 3000mm and non-standard dimensions and shapes, and larger diameters are available on request.
