In the design of the flange mat, according to the convenient installation, depending on the spacer size, 2 to 8 positioning belts on the periphery of the gasket, so that the positioning strip is buckled on the flange hole to prevent the gasket shift or fall off. Saving auxiliary materials and workers. Generally divided into the following types:
The metal winding gasket uses high quality SUS304, SUS316 ("V" or "W" shaped) metal strip and other alloy materials with graphite, asbestos, polytetrafluoroethylene gasket, non-stone cotton and other soft materials alternately overlapping the spiral Based, the metal belt is fixed in a spot welding in a spot welding. The metal winding gasket is a preliminary gasket in a semi-metallic adaptive pad. The metal winding gasket structure density can be made according to different locking force requirements, and the internal and external steel rings can be used to control its larger pressure. The surface precision requirements of the flanged cover of the winding gasket are not high.
The metal winding gasket is particularly suitable for applications where load is uneven, the bonding force is relaxed, the temperature and pressure periodic changes, impact or vibration. The winding gasket is a valve, pump, heat exchanger, tower, human hole, hand hole, and other flanges, ideal static sealing original parts.
