Q235B 1420MM 3PE coated LSAW steel pipe

What is 3PE Epoxy coating pipe?
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.

3PE epoxy coating pipe include 3 layers:
For The first layers is fusion bonded epoxy, which thickness is larger than 100μm. (FBE＞100μm)
The second layer is adhesive, which effect is binding epoxy and PE layers. (AD: 170~250μm)
The third layers is PE layers which is polyethylene have advantages to anti-water, electrical resistance and anti mechanical damage. (φ219-φ1620mm)
Therefore, 3PE coating pipe integrated with the advantages of FBE and the PE. Whichg more and more widely used in buried pipeline’s transporting of water, gas and oil.
In case manufacturing equipment, 3PE coating steel pipe manufacturers they can also do FBE coating pipe.

3PE epoxy coated pipe features and advantages
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

What is FBE (Fusion Bonded Epoxy) coating steel pipe?
FBE coating pipe is Fusion Bonded Epoxy coating steel pipe. It is an externally applied heat resin for pipe. With a form of dry powder at thickness 400-600 microns on to the heated surface of pipe. Once the FBE coated on the pipe surface, the FBE film provides an extremely hard surface with great adhesion to the pipe surface. The FBE layer in a even form and have good resistance to the chemical reaction.
