Description
The metal ring gasket is made of metal material composed of forging and heat treatment and machining into a cross-sectional shape of the entity RX type metal gasket having a radially self-tight sealing effect, is a special octagonal metal ring pad, its role The principle is the inner and outer ladder between gasket groove (mainly outer surface) of the contact, and by pressing to form a seal.
RX-type metal ring gasket mounted ladder ring groove flange when tightening bolts, subjected to axial compression and up and down the ladder groove tie tight, plastic deformation, forming an annular sealing tape, to establish the initial seal. After the boost, the role of media pressure, so that the ring pad radial expansion. Bevel washer and trapezoidal groove more posts tight, resulting in self-tightening effect. However, the media pressure will rise the same flange and bolts deformation, resulting in a relative separation between the sealing surfaces, the gasket than the relative decline, RX type metal ring gasket is belong pressure from the tight ring mat.
Some dimensions of RX-ring pad should pressure through hole penetrating the ring section.
RX-type metal ring mat Features:
1, high temperature, high pressure, for high-pressure flange;
2, durable and reliable seal;
3, adapt to stress, temperature fluctuations of working conditions;
Applications: Typically used in high temperature high pressure steam, gas, pipe flanges solvent, tower tank, pressure vessels, high-speed joints, high temperature and high pressure valve cover. Oil and gas industry in the wellhead and tree seal
