price: contact company for price

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 ~ 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.
