Stainless steel ring joint octagonal gasket

An octagonal-shaped solid metal gasket with a stainless steel ring joint is formed of metal materials through forging, heat treatment, and machining. It is a typical R-shaped metal ring gasket with a radial self-tightening seal function. The basic working idea is to apply pressure to create a sealing effect between the gasket and the inner and outer surfaces of the flange trapezoidal groove (mostly the outer surface).

Stainless Steel Ring Joint Octagonal Gasket

Stainless Steel Ring Joint Octagonal Gasket is a solid metal gasket with an octagonal cross-sectional shape made of metal materials by forging, heat treatment and machining. It has a radial self-tightening seal function and is a standard R-shaped metal ring gasket. The principle of action is to rely on the contact between the gasket and the inner and outer surfaces (mainly the outer surface) of the flange trapezoidal groove, and form a sealing effect by pressing.

The Stainless Steel Ring Joint Octagonal Gasket is installed in the trapezoidal ring groove on the flange surface. When the connecting bolts are tightened, it is compressed axially and tightly against the upper and lower trapezoidal grooves, resulting in plastic deformation, forming an annular sealing band, and establishing an initial seal . After boosting, under the action of the medium pressure, the ring gasket is radially expanded. The gasket and the inclined surface of the trapezoidal groove are more tightly attached to produce self-tightening effect. However, the rise of the medium pressure will also deform the flange and the connecting bolts, resulting in a relative separation between the sealing surfaces, and a relative decrease in the sealing ratio of the gasket. Therefore, the ring gasket can be considered as a semi-self-tight seal.

The matching of Stainless Steel Ring Joint Octagonal Gasket with the flange groove is mainly in surface contact. Compared with the elliptical ring gasket, although it is not easy to achieve a close fit with the flange groove, it can be used again, and it is easy to process because the cross section is made of straight lines. At the same time, the hardness of the Stainless Steel Ring Joint Octagonal Gasket material should be lower than that of the flange surface by 15~20HB.

 

The features of Stainless Steel Ring Joint Octagonal Gasket

1. High temperature resistance and high pressure resistance, suitable for high pressure flanges;

2. Durable and reliable sealing;

3. Adapt to working conditions with fluctuating pressure and temperature;

 

The application range of Stainless Steel Ring Joint Octagonal Gasket

Stainless Steel Ring Joint Octagonal Gasket is usually used in high-temperature and high-pressure steam, gas, solvent pipe flanges, tower tanks, pressure vessels, high-speed joints, high-temperature and high-pressure valves, and covers. Seals on wellheads and Christmas trees in the oil and gas industry.
