TPEP anti-corrosion steel pipe is a kind of pipe with internal and external anti-corrosion. 3PE anti-corrosion steel pipe only refers to external anti-corrosion. Therefore, TPEP anti-corrosion is better than 3PE anti-corrosion in terms of anti-corrosion effect.
The outer 3PE inner sintered epoxy anti-corrosion steel pipe is an upgraded product based on the outer single-layer polyethylene inner epoxy composite steel pipe. It is currently the most advanced form of steel pipe anti-corrosion for buried long-distance pipelines.
TPEP steel pipe is different from ordinary steel pipes in that it has been treated with internal and external anti-corrosion, and the anti-corrosion will not cause any harm to drinking water. With high sealing performance, long-term operation can greatly save energy, reduce costs and protect the environment. It has strong corrosion resistance, simple and fast construction, and a service life of 30-50 years. It also has good corrosion resistance and impact resistance under low temperature conditions, and PE has low water absorption (less than 0.01%). At the same time, it has high strength of epoxy, low water absorption of PE and good softness of hot melt adhesive, etc., and has high anti-corrosion comparability. However, in addition to its many related advantages, 3PE still has relative disadvantages. Its disadvantages are: Compared with the cost of other patching materials, the cost is high.
