Spiral Wound Gaskets
A spiral wound gasket is a gasket made by layering a filler (cushioning material) on a V-shaped metal hoop and winding it in a spiral shape. Also called vortex gasket. It supports high temperature and high pressure, but requires high tightening surface pressure. Main applications include pipe flanges and pressure vessels. Please note that the material used for the hoop filler differs depending on the product, and the maximum operating temperature and pressure also differ. There are four types: basic type only, with outer ring, with inner ring, and with inner and outer rings.
