PVDF管检查井不能带水浇注垫层和基础,要保证基础的几何尺寸和高,符合设计要求,待混凝土达到一定强度才能砌砖。

PVDF管具有:阻燃、耐疲苏不易折断、抗磨损、自润滑性能好,良好的绝缘材料。其机械强度高:与PTFE相比:拉伸强度大2倍,压缩强度大6倍。 耐磨性能:仅稍逊于NYLON6,UHMWPE.当温度压力同时存在时,其性能远优于其他塑料管。

严格控制PVDF管检查井井墙的砌筑质量。井壁必须竖直,不得有增强聚丙烯管通缝;灰浆要饱满,砌缝要平整;抹面要压光,不得有空鼓、裂缝等现象。

全达PVDF钢塑复合管适用于化工、制药、印染、污水处理、冶金薄钢板酸洗,冶金行业废酸回收再生等领域的腐蚀性介质输送。

PVDF管是非常灵活的,有一个94-VO评级,因此不提倡火焰蔓延和抵抗燃烧。
