Metal spiral wound gasket is a kind of sealing gasket widely used. It is a gasket with better resilience in semi metal sealing gasket.
DETAILS:

Metal spiral wound gasket is a kind of sealing gasket widely used. It is a gasket with better resilience in semi metal sealing gasket. It is composed of V-shaped or W-shaped thin steel strip and various fillers alternately. It can be used under high pressure and ultra-low temperature or vacuum conditions. By changing the material composition of gasket, the chemical corrosion problem of gasket caused by various media can be solved, and its structural density can be based on different In order to strengthen the main body and accurate positioning, the spiral wound gasket is equipped with metal inner reinforcing ring and outer locating ring, and the internal and external steel ring is used to control its large compression degree, and the surface accuracy requirement of flange sealing surface contacted by gasket is not high.

The metal winding gasket is made of SUS304, SUS316 (V-shaped or W-shaped) metal belt and other alloy materials, graphite, asbestos, polytetrafluoroethylene gasket, non asbestos and other soft materials alternately overlapped and spirally wound, and the metal belt is fixed by spot welding at the beginning and end. The spiral wound gasket is the gasket with better resilience in the semi metal sealing gasket. The structural density of the spiral wound gasket can be made according to different locking force requirements, and the internal and external steel rings are used to control its large compression degree. The surface accuracy requirement of the flange sealing surface contacted by the spiral wound gasket is not high. Metal spiral wound gasket is especially suitable for uneven load, easy relaxation of bonding force, periodic change of temperature and pressure, impact or vibration. Spiral wound gasket is an ideal static sealing element for valve, pump, heat exchanger, tower, manhole and handhole.
