Inner ring and outer ring metal wound gasket !

Sealing gasket
The inner and outer metal wound gasket is a kind of sealing gasket widely used, which is the best springback gasket in the semi-metal close gasket. It is composed of V-shaped or W-shaped thin steel strip and various filling materials.

Introduction
Resistant to high temperature, high pressure and adapt to ultra-low temperature or vacuum conditions, by changing the material combination of the gasket, can solve the chemical corrosion problem of various media gasket, its structural density can be made according to different locking force requirements, in order to strengthen the main body and accurate positioning, the wound gasket is equipped with a metal inner strengthening ring and an outer positioning ring, the use of internal and external steel rings to control its maximum compression. The surface accuracy of the sealing surface of the flange contacted by the gasket is not high.

Main Use
The internal and external metal winding gasket with excellent resilience can automatically adjust the pressure and thermal cycle and vibration of the pipeline system, especially for the occasion of uneven load, easy relaxation of the joint force, periodic changes in temperature and pressure, shock or vibration. It is the static sealing original of valve, pump, heat exchanger, tower, manhole, hand hole and other flange joints, widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments. In order to facilitate installation in the appearance design of the flange pad, 2~8 positioning belts are welded on the periphery of the gasket according to the diameter of the gasket, so that the positioning belt is buckled on the flange hole to prevent the gasket from shifting or falling off during installation, saving auxiliary materials and working hours. Generally divided into the following types: the internal and external metal wound gaskets are made of high quality SUS304, SUS316 (" V "shape or" W "shape) metal belts and other alloy materials and graphite, asbestos, polytetrflon, asbestos-free and other soft materials alternate overlapping spiral wound, at the beginning and end with spot welding method to fix the metal belt. Metal wound gasket is the best springback gasket in semi-metal close gasket, and the structural density of metal wound gasket inside and outside can be based on different locks !
