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

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.
