Product Detail
1.Applicable to a wide range 2.Excellent sealing performance 3.The different requirements of processing into various shapes

1) Definition:

Spiral Wound Gasket is the ideal gasket in the semi-metallic category. A narrow strip of V-shap metal hoop is spirally wound under tension with a filler cushion between the lamination of the metal and is spot-welded at both ends.

2) Characteristics: good compressibility and rebound elasticity, with multi-channel sealing and certain self-tightening functions, not sensitive to the surface defect of flange clamping plane, and not binding the flange sealing surface, convenient to be dismantled as it is easy to be adjusted to the middle, able to partially get rid of pressure, and the influences of temperature change and mechanical vibration; capable of keeping very good sealing performance under some tough conditions of circulating alternation, such as high temperature, low temperature, high vacuum, impact vibration, etc.

3) Application: widely applied in static sealing parts of technological pipelines, and the equipments of many industries, such as petroleum refining, petroleum chemistry, chemistry, thermal electricity, nuclear energy, spaceflight, spinning, medicine and other industries.
