三、施工原则

Underground pipeline, pipe anti- corrosion work by professional 3PE coating

manufacturers, in Chongqing area 3PE coating technology and scale of production to reach the coastal

areas of the corrosion and scale, is now the Chongqing area 3PE pipeline coating production in the

range of 20-950mm, the diameter more than 950mm pipe using thermal belt winding anticorrosion,

and all fittings, mending, welding using the same PE shrink with anti-corrosion, anti-corrosion

processing plant in the above work focused on the complete, reach the maintenance period,

transported into the construction site installation, pressure test after passing the required repairing

and mending.

地下管道 、

管件防腐工作由专业

3PE

防腐厂家 完成，

鉴于重庆地区

3PE

涂敷技术及 生产规模达不

到沿海地区的防腐水平及规模，现目前重庆地区

3 PE

管道防腐生产范围在

20-950mm

，对于管径超过

950mm

的管道采用热缩带缠绕防腐，且 所有管件、补伤、焊口同样采用聚乙烯热缩带防腐，以上防

腐工作集中在加工厂内完成， 达到养护期后，运入施工现场安装，试压试验合格后按规定补口补伤。
