       石棉金属缠绕垫片是目前应用广泛的一种密封垫片,是半金属密合垫中回弹性最佳的垫片,由V形或W形薄钢带与各种填充料交替缠绕而成,能耐高温、高压和适应超低温或真空条件。通过改变垫片的材料组合,可解决各种介质对垫片的化学腐蚀问题,其结构密度可依据不同的锁紧力要求来制作。为加强主体和准确定位,石棉金属缠绕垫片设有金属内加强环和外定位环,利用内外钢环来控制其最大压紧度,对接触垫片的法兰密封面的表面精度要求不高。
      Metal wound gasket with asbestos is a type of widely used sealing gasket at present, and its resilience is regarded as the best in semi metallic gasket. Wounded together alternately by V or W shaped steel strips and various fillers, the product has good heat resistance, high pressure resistance and adapt to the use of ultra low temperature or under vacuum conditions. Through changing the material combination of the gasket, the problem of all kinds of medium chemical corrosion on the gasket can be solved. The structure density can be made according to different locking force requirements . In order to strengthen the body and accurate positioning, the inner reinforcing ring, outer locating ring ,inner and outer steel ring are set within the asbestos metal winding gasket to control its biggest compaction degree. It doesn’t have much requirements on the precision of the flange sealing surface contacted with the gasket.

 

适用范围 Application scope
      回弹性优良的石棉金属缠绕垫片能够对管道系统的压力热循环和振动进行自动调整,特别适用于负荷不均匀、接合力易松弛,温度与压力周期性变化、有冲击或震动的场合,是阀门、泵、换热器、塔、人孔、手孔等法兰连接处的静密封原件,广泛地用于石化、机械、电力、冶金、造船、医药、原子能和宇航等领域。
      Asbestos metal winding gasket with excellent resilience can be automatically adjusted towards the pressure thermal cycling and vibration of the piping system . It is especially suitable for the situations with inhomogeneous load, slack composition of forces , periodical changes of temperature and pressure ,impact or vibration. It is the original static sealing in flange connection of valves, pumps, heat exchangers, towers, handholes, etc and is widely applied in sectors of petrochemical, machinery, electric power, metallurgy, ship ,building, medicine, atomic energy and aerospace.
