第一类：PTFE衬里荔管及发配件
俗称松衬管。此工艺采用PTFE棒材车削成的薄膜，缠绕烧结成形。适用于常压、正压的输送
管路(如三产生负压的废处理管路等)，不宜用于有负压的管路(如泵进、出口处及由落差或突然泠却等能
管路

第二类:PTFE紧衬直管及管配件
俗称内缠钢丝紧衬管，我厂专利产品
制造工艺：先将若干层PTFE薄膜缠绕在模具土，再将钢丝(eo．5—1mm)螺旋形地缠绕在
PTFE薄膜土，然后在钢丝外面再缠绕若干层PTFE薄膜，最后放在炉中烧结成形。用这种工艺
制作的PTFE衬里管，内壁光滑，外壁由于钢丝的体积及其外
弹力量，形成螺旋形浅波纹。将它衬入钢管内，并在PTFE衬里管外壁与钢管内壁之间的空隙处
灌满填充树脂(排出残留空气)。这种填充树脂能与钢管紧密粘结在一起。同时，它能紧紧地包
裹在螺旋形的PTFE衬管外壁土。填充树脂固化后，就形成了与衬里外壁波纹相晈合的螺旋形波
纹。这种结构，类似与螺母与螺栓的结合。它一方面能使PTPE衬里的热胀泠缩得到有效的限制
和补偿；另一方面，利用钢丝的刚度明显地提高PTFE衬里耐负压的能力

第三类：PTFE推《挤》赃管鲎衬直管
俗称推(挤)压衬里管，系90年代发达国家普遍采用的管道。
PTFE衬管壁厚(mm)
造工艺：首先采用进[1PTFE粉末，推(挤)压成管子，然后将它强行拉入无缝钢管(衬管外径
略大于钢管内径1．5—2mm)，形成无间隙紧衬。为了消除应力，将它放在炉中，加温至180~C进行
恒温处理，使之适应在1
80~C以下的温度中使用。同寸，推(挤)压管的轴向抗技强度比缠绕管明显要
好。此管道具有理想的耐正、负压能力。
