Product Details

SUS316 Spiral Wound Gasket with Inner Ring

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. 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.
