The anti-corrosion steel pipe with inner EP epoxy and outer PE coating is mainly made of spiral welded steel pipes, which are heated internally and externally. The outer wall of the steel pipe is hot-dip coated with polyethylene particles, and then a layer of EP epoxy resin is coated on the inner wall of the steel pipe. The anti-corrosion steel pipe with inner EP epoxy and outer PE coating is used for water supply and drainage pipelines, which can transport various water qualities and is mainly used in the construction of underground pipeline networks. Due to the excellent anti-corrosion effec

内EP环氧外PE涂塑层防腐钢管,主要是由螺旋缝焊接钢管,经过内外加热,在钢管的外壁热浸聚乙烯颗粒,然后在钢管内壁涂覆一层EP环氧树脂制作而成。

内EP环氧外PE涂塑层防腐钢管用于给排水管道,可输送多种水质,主要在地下管网的建设中使用。因其外聚乙烯防腐层具有很好的防腐效果,而且成本较低,因此内外防腐钢管的外层防腐多采用这种方式进行制作。

内EP环氧外PE涂塑层防腐钢管使用较多的还是螺旋钢管,一是因为无缝钢管的口径一般较小,采用聚乙烯进行涂覆的时候,其厚度受到一定的限制。二是无缝钢管的成本相对来说也高一些,而且一般管道输送的介质压力也不大,使用螺旋钢管生产完全可以满足设计要求。

内EP环氧外PE涂塑层防腐钢管经常也被称为外PE内EP涂塑钢管,或者外聚乙烯内环氧涂塑钢管或者防腐钢管,因其工艺的原因,名称有很多,叫法也是因人而异。
