NXF UNS S316/0Cr17Ni12Mo2/1.4401 Diameter 1-100mm Grade 100-300HV Stainless Steel SS316 Eight-sided Gasket Octagonal Gasket
Its working principle is the contact between the backing sheet and the inside and outside (mainly the outside side) of the flange ladder groove, and the sealing effect is formed by pressing.
The octagonal Ring joint gasket is installed in the ladder ring groove on the flange surface. When the connecting bolts are
tightened, they are tightly attached to the upper and lower ladder groove under axial compression, resulting in plastic
deformation, forming an annular sealing belt, and establishing the initial seal.
After boosting, the Ring joint gasket expands radially under the action of medium pressure. The gasket is more closely attached to the inclined plane of the trapezoidal groove, resulting in self-tightening effect.
its corrosion resistance and high temperature strength. It can withstand high temperatures up to 1200-1300 degrees and can be used
under harsh circumstances.316 Applications
* 1) Pulp and paper equipment;
* 2) Heat exchanger;
* 3) Dyeing equipment;
* 4) Film processing equipment;
* 5) Pipeline;
* 6) Materials for exterior construction in coastal areas;
* 7) Solenoid valve field (housing, clamp, ball, valve body, valve seat, nut, valve stem, etc.);
Its working principle is the contact between the backing sheet and the inside and outside (mainly the outside side) of the flange ladder groove, and the sealing effect is formed by pressing.
The octagonal Ring joint gasket is installed in the ladder ring groove on the flange surface. When the connecting bolts are
tightened, they are tightly attached to the upper and lower ladder groove under axial compression, resulting in plastic
deformation, forming an annular sealing belt, and establishing the initial seal.
After boosting, the Ring joint gasket expands radially under the action of medium pressure. The gasket is more closely attached to the inclined plane of the trapezoidal groove, resulting in self-tightening effect. However, the increase of medium pressure will also deform the flange and connecting bolt, resulting in the relative separation between the sealing surfaces and the relative decrease of gasket sealing ratio. Therefore, the ring gasket can be considered as a semi self-tightening seal.
