R45 stainless steel metal octagonal gasket for flange * price

The octagonal metal ring gasket is installed in the ladder shaped groove on the flange surface. When the connecting bolt is tightened, it is compressed axially and pressed against the upper and lower ladder shaped grooves, causing plastic deformation and forming an annular sealing band, establishing the initial seal. After the pressure is increased, the ring gasket expands radially under the action of the medium pressure. The gasket is more tightly attached to the inclined surface of the trapezoidal groove, creating a self tightening effect. However, the increase in medium pressure can also cause deformation of the flange and connecting bolts, resulting in relative separation between the sealing surfaces and a relative decrease in the sealing ratio of the gasket. Therefore, the gasket can be considered a semi self tight seal.Octagonal gasket is a solid metal gasket with an octagonal cross-sectional shape made of metal material through forging, heat treatment, and mechanical processing. It has a radial self tightening sealing effect and is a standardA type of R-type metal ring gasket, whose working principle is the contact between the cushion plate and the inner and outer surfaces (mainly the outer side) of the flange ladder groove, and the sealing effect is formed by compression.

Material: Carbon Steel, Stainless Steel304, 316, etc

Shape: Octagonal, Elliptical

Scope of application: Temperature:-200-800 ℃ pressure: 2.0-42 megapascals

Suitable for flange sealing of high temperature and high pressure pipelines.

Metal ring pads originated in the United States and were used inIn the early 1920s, it was used in the field of boilers, and later in the sealing of manhole covers and other windows of high-pressure reactors. Later, it was particularly valued in petroleum production and refining industry. As the temperature and pressure of steam power plants increase, the use of metal gaskets becomes increasingly widespread.

Octagonal cushionSolid metals of various materials are selected and machined using CNC machine tools. The material of the metal ring gasket is generally soft iron/SS304/SS316/carbon steel/SS321 and other alloy materials. Metal ring pads have excellent characteristics of high temperature resistance, high pressure resistance, and corrosion resistance. If the material is appropriate, it can be used in high temperature (1000 ℃) and corrosive working conditions, and can withstand high pressure or alternating pressure (1500bar). Metal ring gaskets are mainly used for machine joints such as high temperature and high pressure pipelines (steam and petroleum industry, petrochemical industry) towers, tanks, heat exchangers, pipelines, etc. Applicable standards: ANSI B16.20, HG20633-97, API6A, SH, etc.
