1、金属缠绕式法兰密封垫片定义              
                                                                              
金属缠绕式法兰密封垫片是由金属带和非金属带螺旋复合绕制而成的一种半金属平密封垫片。              
                                                                              
 2、金属缠绕式法兰密封垫片性能：              
                                                                              
 ①  压缩、回弹性能好，具有多道密封和一定的自紧功能;              
                                                                              
 ②  对于法兰压紧面的密封表面缺陷不太敏感，不粘结法兰密封表面，容易对中，因而拆装金属缠绕式法兰密封垫片时比较便捷;              
                                                                              
 ③  金属缠绕式法兰密封垫片可部分消除压力、温度变化和机械振动的影响;              
                                                                              
 ④  金属缠绕式法兰密封垫片能在高温、低温、高真空、冲击振动等循环交变的各种苛刻条件下，保持其优良的密封性能。
