The spiral wound gasket is the most ideal type having flexibility and recovery which are essential for high temperature and high pressure among semimetal gaskets. It is wound in spiral combined with V-type metal thin hoop and non-ferrous material filler. The winding start part and end part are wound by the hoop over several times and then both edge is processed by spot welding to make the gasket. The gasket has outstanding capability as it features unique structure with elastic metal and flexible filler.

Feature

• Outstanding capability for high temperature and high pressure
• Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditions
• Efficient production for any type of dimensions such as round or oval type, etc.
• Outstanding sealing capability as it is produced according to the pressure of unbalanced flange.
