金属包覆垫片和金属缠绕垫片要在工业生产和日常生活中经常用到的密封材料,但是对于这几种密封垫片,很多消费者都不清楚两者的差别,下面就带您来了解。

单就金属包覆垫片而言,金属缠绕垫片材质内部关键应用非金属材质,外界应用特定的冷作工艺报复金属板材的复合性垫片,可以说是传统的一种密合垫片,适用于换热器,压力容器,泵,阀及其法兰面密封,相比而言,回弹性有限,必须确保法兰面平坦而且拧紧力很高才可以达到练好的效果。而金属缠绕垫片标准则主要采用优质金属带以及其他合金制品与石墨、石绵、聚四氟乙烯、无石棉等软性材料互相更替重合螺旋盘绕成的,在开始及尾端用焊接方式将金属带固定。可以说,金属缠绕点偏是半金属密合垫中回弹力佳的垫片,其结构密度能够根据不同的卡紧力规定来制作,而且运用里外钢环来控制其大卡紧度,而对垫片接触的法兰密封面的表面精度要求不高。
