Product details

Spiral wound gasket (SWG) consists of thin metal hoop and nonmetal filler material which are simultaneously wound. The metal hoop is pre-formed in V or W shaped profile, which allows the gasket to act as a spring between the flanges.  spiral wound gasket can be fabricated of any metal which is available in thin strip and which can be welded; so they can be used against virtually any corrosive medium dependent upon the choice of the metal and filler.

 

It is extremely popular due to the wide variety of available styles and sizes. Depend on its excellent compression resilience, it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc.

 

During the rolling-up of a profile metal tape, a filler is being included. It is PTFE or expanded graphit. The v-profile metal tape is produced by different metal materials or steels. The flexibility of the gasket in pressing on direction is being upgraded due to the v-shape cross-section.
