3PE anti-corrosion steel pipe for buried pipeline life is critical, the same material pipes buried in the ground for decades and some non-corrosive, and some years it leaks occur. Because they use different outer coating. 

In which ordinary steel for use in harsh environmental conditions, there will be severe corrosion, which will reduce the life of the steel pipe, steel pipe anti-corrosion insulation life is relatively long, generally, it can be used under normal circumstances for 30-50 years, and the proper installation and use is also possible to make the pipe network maintenance costs low, anti-corrosion pipe insulation can also set an alarm system, automatic leak detection pipe network failures, accurate knowledge of fault location and will automatically alarm. 

3PE anti-corrosion steel pipe insulation performance is good, heat loss is only 25 per cent of the traditional pipe, long run can save relatively large resources, significantly reduce energy costs, and still has a relatively strong waterproof and corrosion resistance, and has no need trench directly on the ground or water can be purchased, but also easily and quickly on the construction, relatively low cost integrated, also at low temperatures and has good corrosion resistance, impact resistance, and in certain circumstances You can also directly embedded in permafrost.
