3LPE coating

3LPE coating (3PE/3LPE) outer coating can perfectly solve this problem. 3LPE coating material consist of a high performance fusion bonded epoxy (FBE) layer, an copolymer adhesive layer and an top polyethylene layer of high density polyethylene. The three-layer outer coating has excellent wear resistance, acid, alkali and cathodic disbonding properties.

When transporting crude oil, natural gas or refined products over long distances, it is often necessary to bury pipelines in the ground. When spiral steel pipes or fittings come into contact with soil and water, their external anti-corrosion properties must be considered to ensure a long service life of the pipes.

3LPE coating (3PE/3LPE) outer coating can perfectly solve this problem. 3LPE coating material consist of a high performance fusion bonded epoxy (FBE) layer, an adhesive layer and an outer layer of high density polyethylene. The three-layer outer coating has excellent wear resistance, acid, alkali and cathodic disbonding properties.

 

Composition of 3LPE coating

The first layer (FBE > 100um) consists of fusion bonded epoxy. This layer prevents corrosion and fuses with the shot peened steel surface.

Layer 2 (170~250um) is a copolymer adhesive with excellent chemical adhesion to the inner and top layers of polyethylene

The third layer (2.5~3.7mm) is a polyethylene layer to prevent any physical damage to the pipe

3LPE coating are firmly combined with the steel pipe to form an excellent anti-corrosion coating, which can be used in the range of 25Φ~2420Φ.

3-layer polyethylene coated steel pipe is the first choice for the transmission of oil and gas around the world, it can withstand a variety of temperatures and environments from sweet dry land to deep water. 3 layer polyethylene coated steel pipe is used for drinking water, oil and gas transportation. Gases and other fluids. 3LPE coated pipes can be used at high temperatures up to 60°C to 80°C.

 

Application of 3LPE coating

3LPE coating is widely used in oil and gas pipeline anticorrosion.

 

The development prospect of 3LPE coating

At present, the commonly used external anti-corrosion coatings for pipelines around the world include: petroleum asphalt (AE), coal tar enamel (CTE), frit-bonded epoxy powder (FBE), three-layer polyethylene coating (3LPE coating) and three-layer polypropylene Coating (3LPP) etc. 

From the perspective of development trends, 3LPE coating has already taken an advantage in the international pipeline coating market competition, and its market share will continue to expand, while the FBE market is slowly shrinking.

As an anti-corrosion coating on the outside of the pipeline, the 3LPE anti-corrosion coating has a minimum thickness requirement, so the application cost is high. At the same time, the failure of its patch also affects the safe operation of the pipeline.

Therefore, in recent years, in view of the new problems encountered in the use of pipeline coatings, coating manufacturers in various countries have improved materials on the basis of traditional FBE and 3LPE, or developed new coatings, and have achieved practical application value. Results, and gradually applied to production.
