The main purpose

The metal spiral wound gasket with excellent resilience can carry out pressure thermal cycling and vibration of the pipeline system

Automatic adjustment, especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Is the valve

The static sealing elements at the flange joints of doors, pumps, heat exchangers, towers, manholes, hand holes, etc., are widely used in petrochemical, machinery, electric power, metallurgy, manufacturing

Shipbuilding, medicine, atomic energy and aerospace departments.
In the design of flange gasket, for the convenience of installation, 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.

On the hole, to prevent the gasket from shifting or falling off during installation, saving auxiliary materials and man-hours. Generally divided into the following types:
Metal spiral wound gaskets are made of high-quality SUS304, SUS316 ("V" or "W" shape) metal belts and other alloy materials with graphite, asbestos, poly

Soft materials such as tetrafluoroethylene gasket and non-asbestos are alternately overlapped and spirally wound with each other, and the metal tape is fixed by spot welding at the beginning and the end.

Metal spiral wound gaskets are semi-metallic gaskets with good resilience. The structure density of metal spiral wound gaskets can be made according to different locking force requirements.

The inner and outer steel rings are used to control the super tightness, and the surface accuracy of the flange sealing surface contacted by the wound gasket is not high. Metal wound gasket

The sheet is especially suitable for occasions where the load is uneven, the joining force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Spiral wound gasket is a valve

Flanges such as doors, pumps, heat exchangers, towers, manholes, hand holes, etc.
