Durable Lifetime

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.

Corrosion Resistance

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.

Flexibility

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.

Excellent Resistance of Impact & Earthquake

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.

Outstanding Wear Resistance

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.

Prime Environment Protection Performance

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.

SUPErb Electric Resistance  Anti-Static Performances.

These properties make PE pipeline suitable for flammable  explosive conditions.

Safe  reliable connection way

3PE coating steel pipe mainly use hot melt  fused connection, keep the interface  pipeline connect as a whole. There is no water  gas leakage.

Light, easy to move,  convenient for construction

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.
