La description

Octagonal metal ring gasket

installed inside a ladder type ring groove on the surface of the flange, when screw down the connecting bolt, the axial compression and up and down the ladder type slot 1, produce plastic deformation, forming a ring seal belt, establish the initial seal.After booster, under the action of medium pressure, make the ring gasket radial expansion.Gasket with trapezoidal groove cant post more tightly, self-tightening effect.Medium pressure increases, however, also can make the flange and the connecting bolt deformation, caused by a relative separation between the sealing surface, gasket seal than relative decline, thus, ring gasket can be thought of as a half since the tight closure. 
 

Octagonal metal ring gasket

It mainly match with flange groove is surface contact, compared with the oval ring gasket though with flange groove or not easily, but it can be used again, and because of the cross section is made up of straight line easy processing.At the same time choose octagonal metal ring gasket material should be lower than the flange surface hardness 15 ~ 20 hb 
 

Note

When octagonal type is chosen, the material hardness of the pad should be 15~20HB lower than that of the flange face. It is recommended the
pad is not recycled.
