Spiral wound gasket manufactured by wealson is widely uesd 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.
Wealson graphite composite gasket is also called reinforced graphite gasket or high-tensile graphite gasket. Graphite gasket is cut from pure graphite sheet with features excellent corrossion-sesistance, metal reinforcement, high and low temperature resistance, high internsity.
It can be bear high temperature and high pressure. Graphite gasket is ideal gasket for valves and static seal in almost all applications. Graphite gasket can be used as sealing parts of connection point of all kinds of pumps, pipes, valves, pressure containers, heat exchangers, tower manhole, hand-hole and flange, as well as the sealing points of nilometer crystallizer and liquidometer.
This kind of material manufactured by Wealson can be reinforced with various inserts such as stainless steel, stainless steel tanged (perforated) sheet, wire screen mesh, etc.
Wealson Graphite Laminates have excellent mechanical strength and handleability, exhibit low creep relaxation,stable compressibility and recovery characteristics.
They are widely used to provide narrow cross-section gaskets and for many high-pressure industrial applications. It is widely used in the fields of petroleum & chemical industry, refining, electric power, metallurgy, machinery, papermaking, automobile, shipping building, pharmacy, aerospace industry, nuclear industry, etc.
Wealson is the leader manufacturer of flexible graphite materials in China.As gasket material for Graphite Gasket, Spiral Wound Gasket, Die- Fored Graphite Rings,, it is usually fabricated into Graphite Laminate, and widely used in fluid sealing, It can also be used as solid lubricant in metal stamping and forming applications, or as heat liner in industry furnaces and other heating devices.
Flexible Graphite Sheet in Rolls are available in various dimensions, densities, and in grades ranging from 98 up to 99.9% carbon content minimum
Because of its chemical, physical and mechanical properties, flexible graphite based seals, gaskets are being used in
