    octagonal or elliptical solid metal gasket, having a radial self tight

    seal effect. The metal ring gasket cushion plate and flange of

    trapezoidal grooves of the inner and outer side surfaces ( mainly

    outside of the outer side) contact, and through pressing and forming a

    seal. Metal ring padMetal ring gaskets originated from the United

    States, in the nineteen twenties was first used in boiler field, used

    for the manhole cover, autoclave and other container sealing, later in

    the oil production and oil refining industry attracts more and more

    attention, with the steam temperature and pressure increase, metallic

    ring gaskets have been used more and more widely. Metal ring pad used

    for nominal pressure is 2 ~ 42.0MPa.2, classificationMetal ring pad is

    divided into octagonal ring gasket and elliptical pad two. Metal ring

    gasket according to the cross section shape is octagonal and oval two

    structure.Octagonal ring gasket and the flange groove matches, mainly

    for surface contact. The oval ring gasket is compared, although not easy

    with the groove in the flange to close together, but can use again, and

    because the section is composed of straight lines, easy processing. Oval

    ring gasket on the flange groove is line contact, better sealing

    performance, but requires high processing precision, thus increasing the

    manufacturing cost, at the same time oval ring gasket can not be used

    repeatedly.In 3, the gasket standardsGB / T9130-2007; JB / T89-1994; SH3403-

    1996; HG20633-2009( American system ); HG20612-2009( European system

    );In 4, the gasket characteristicsIn 1, high temperature resistance,

    high pressure resistance, suitable for high pressure flange seal;2,

    durable and reliable;3, adapted to the load frequency variable working

    condition;5, corrosion resistance and low hardness of metal ring

    padCorrosion resistance of low hardness metal ring pad : the custom of

    low carbon content of trace elements in metal materials, adjust, change

    the ordinary heat treatment methods to ensure the implementation of low

    hardness metal ring pad. Products are widely used in petrochemical,

    chemical, metallurgy, refining, gas, nuclear power, thermal power and

    other industries of high temperature, high pressure equipment, process

    piping static sealing parts.
