3PE coated steel pipe can prolong above 50 years. It is because 3PE coating has good stability anti-aging performances under normal work temperature pressure conditions.
The elements of PE structure stability is high. So we can use it to prevent corrosion natural gas, liquefied petroleum gas, artificial gas, other chemical subjects. it needs no secondary anti-corrosion equipment. The chemical of soil does produce any effects on the steel pipe using 3LPE coating.
3PE coating is a kind of soft flexible material, it breaks after prolong 5 times longer. It is easy to bend without damage. 3PE coating steel pipe can bypass steel pipe reduce the fees of installation.
One of the important features of 3LPE coating is that 3pe is fragile under low temperatures. The temperature at the range of -60℃~60℃ is safe. So it can adapt to going down of pipeline work in winter. 3PE pipeline won’t easily to break due to its good impact performances.
Tests show that PE pipe’s wear resistance is 4 times than bare steel pipe. Especially transporting mud, compared with varnished steel pipe, PE coated pipe has better performance of wear resistance. 3PE has a smooth surface, its manning coefficient is 0.009.
3PE coated steel pipes have smooth internal surface non-sticking performance, so it shows a higher ability for transporting water, it reduces the loss of pressure when transporting.
Comparing with other coating systems FBE coated pipes, 3PE coated steel pipe’s low water permeation characteristic can improve the ability of isolation seawater.
PE material is a kind of green material without any harm poison. It won’t add heavy metal stabilizers in the manufacturing process of 3LPE coated steel pipelines. 3PE can recycled, so it will cause pollution to the environment.
These properties make PE pipeline suitable for flammable explosive conditions.
3PE coating steel pipe mainly use hot melt fused connection, keep the interface pipeline connect as a whole. There is no water gas leakage.
3PE’s weight is light. It only accounts 1/8 weight of steel pipe. It is easy to move, to bend. its welding process is convenient fast. It has obvious economic benefits in the whole project.
