タイトルまたは説明
Metal ring gasket is made of metal materials into the section
shape is 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 ~ *2.0MPa.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 / T********7; JB / T******4; SH********6;
HG*********9( American system ); HG*********9( 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.
