The effection of outer and inner ring for spiral wound gasket
Spiral wound gasket on the flange gasket design for easy installation, according to the gasket diameter size, 2 ~ 8 on the gasket peripheral welding positioning belt, let positioning buckles on the flange hole, in case the shift of the gasket when installation or fall off, save the auxiliary materials and working hours. Spiral wound gasket inside and outside the steel ring is used to control the maximum compaction degree, winding gasket contact with the surface of the flange sealing surface accuracy is not high. The spiral wound gasket is especially suitable for the situations where the load is uneven, the joint forces are easy to relax, the temperature and pressure are changed periodically, and there is shock or vibration. The spiral wound gasket is the ideal static seal of valve, pump, heat exchanger, tower, manhole, hand hole, etc.
