3LPE Coated Pipes,API 5L LINE PIPE WITH 3LPE COATING,API 5L Grade X42 3LPE Coated Steel Line Pipe

3-Layer Polyethylene (3LPE) is a multilayer coating composed of three functional components: A high performance Fusion Bonded Epoxy (FBE) primer, followed by a copolymer adhesive and an outer layer of polyethylene which provides tough, durable protection. 3LPE systems provide excellent pipeline protection for small and large diameter pipelines operating at up to moderately high temperatures

3 LPE pipe,three layer polyethylene coating steel pipe, conforming to DIN 30670 standard.

DIN 30670 is a polyethylene coating on steel pipes and fittings. Requirements and testing.

This anti-corrosive coating consists of the following layers:

Layer 1: Usually the corrosion protective layer. This layer is of combination bonded epoxy which offers exceptionally good corrosion protection. The fusion reinforced epoxy contains a very great holding with the blasted steel surface

.Fusion Bonded Epoxy. This later provides protection against corrosion and is fusion bonded with the blasted steel surface.;

Layer 2: This layer is the copolymer adhesive. The copolymer adhesive could be a maleic anhydride united polyethylene compound. This material has great chemical holding to the fusion reinforced epoxy and the beat layer polyethylene.

Layer 3: This layer is for physical protection and comprises polyethylene. Since the copolymer adhesive and polyethylene are comparable, they bond well with each other

Layer1 of minimal thickness of 80 µm,layer2 of minimal thickness of 250 µm,Then Whats the specification for the thickness of 3LPE coating?Minimum total thickness of polyethylene coating shall be as below:

Normal size Minimum Total Coating Thickness
Normal type Reinforced type
≤DN 100 1.8 2.5
˃DN100  ≤DN250 2.0 2.7
˃DN250  <DN500 2.2 2.9
≥DN500  <DN800 2.5 3.2
≥DN800 3.0 3.7

Characteristics of 3PE coated steel pipe :

  • High tightness. It can save energy, reduce costs, protect the environment in long-term operation.
  • Corrosion resistance is very strong. The construction side simply speed. Up to 30~50 years service life.
  • With good resistance to corrosion and impact resistance, low water absorption. The PE ( less than 0.01% ) at low temperatures.
  • High strength epoxy. PE absorbent and hot melt adhesive softness, etc. have high corrosion reliability.

Features and Advantages of 3LPE Coated Steel Pipe

1. Excellent chemical and corrosion resistance preventing steel pipes from any damage.
2. Resistance to cathodic disbondment
3. The external layer of polyethylene prevents any physical damages to either the pipes or the fusion bonded epoxy during handling
4. The 3LPE coated pipes have high performance characteristics and an extended life cycle

We provide externally coated carbon steel pipes with 3LPE coating for applications in buried or submerged environments. We  also supply other anti corrosion pipeline coatings such as 3LPP, FBE and internal epoxy coatings.
