The 3PE Epoxy coated steel pipe is with 3 layer coatings, first FBE coating, middle is adhesive layer, outside polyethylene layer. 3PE coating pipe is another new product developed on the FBE coating basis since 1980s, which contains adhesives and PE(polyethylene) layers. 3PE can strengthen the pipeline’s mechanical properties, high electrical resistance, waterproof, wearable, anti-aging. It could protect pipe from the heat loss which only account for 1/4 of pipe. Let’s see why 3PE coated pipe is more advantage than FBE coated pipe.

Durable lifetime

3PE epoxy coated steel pipe have good stability and anti-aging performances under the normal work temperature and pressure conditions, consequently its lifetime can prolong above 50 years.

Corrosion resistance

Due to PE elements structure stability is very high, it is resistant to corrosion of natural gas, liquefied petroleum gas, artificial gas and other chemical subjects, no need secondary anti-corrosion equipment. The chemical of soil does not produce any effects to the pipe.

Flexibility

3PE is a kind of soft and flexible material, it can prolong 5 times length then break. While it is easily to bend and no damage. 3PE coating steel pipe can bypass objects and cut the fees of installation.

Good resistance of impact and earthquake

Polyethylene is not fragile under low temperature, there for, it is safe used in the temperature at the range of -60℃~60℃. So it can adapt to going down of pipeline, Work in winter. Due to good impact performances, PE pipeline won’t easily to break.

Excellent wear resistance

Experiments shows that PE pipe wear resistance is 4 times of pipe. especially in area of transporting mud. Compared to varnished pipe, PE coated pipe have better wear resistance.

3PE have smooth surface, its manning coefficient is 0.009. Because of smooth internal surface and non-sticking performance, 3PE coated steel pipe shows higher ability for transporting, and reduce the loss of pressure and water transporting. Low water permeation characteristic provides improved isolation from sea water compared to the other coating systems and FBE pipe.

Good environment protection performance

3PE coated steel pipelines in manufacturing process won’t add heavy metal stabilizer, the PE material have no poison and harm, is a kind of green material, and itself can recycled will not cause pollution to  the environment.

Excellent electric resistance, anti-static performances.

These properties make PE pipeline suitable for flammable and explosive conditions.

Safe and reliable connection way

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

Light, easily to move, and convenient for construction

3PE’s weight only account 1/8 for steel pipe, easily to move, bend, welding process is convenient and fast, lower fees for whole project, obvious economic benefits.
