Spiral wound gasket

1. Wide range of applicable working condition 2.Strong stress compensation,stable sealing performance 3.Easy to installation

    Spiral wound gasket consists of "V-shape"(or"W-shape")metal tape and nonmetal tape,which are overlapped each other and wound continuously.To fasten the metal tape,both its start point and end point are tack welded.

Products  Features

Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.Perfect sealing performance.Normal requirement of flange surface finishing which contact with gasket.Easy installation and low pre-tightening stress of gasket.
