3LPE STEEL PIPE COATING AND ITS ADVANTAGES IN THE PIPELINE INDUSTRY

What is the pipe coating?

A pipeline coating is a cost-effective and viable solution to maintain pipelines' integrity. To save the pipelines from getting damaged, or get effected through corrosion, this coating provides a constant protective lining. Pipeline coating is said to be one of the most reliable corrosion prevention methods used by the industries today.

Why do Pipelines need Coating?

Pipe coatings protect pipelines from corrosion-related defects. They are just one element of the total package operators employ to ensure their pipelines are well protected. Cathodic protection and integrity assessments are also used to prevent corrosion, and to detect any defects that may result from corrosion.

What is 3LPE Pipe Coated Steel Pipe?

3LPE coated steel pipe also called as 3PE is one kind of coating method which used in carbon steel pipe. No matter which pipe it is, whether it is a seamless steel pipe, welded steel pipe, stainless steel pipe or alloy steel pipe, it can do 3LPE coating for the pipes. The Common use of 3LPE coated steel pipe is in the Pipeline Industry. As carbon steel pipe is widely used in pipeline systems for transportation of oil, gas, water and other fluids.

Features of 3LPE Pipe Coating

·         3LPE coating Steel pipes has high tightness, as it can save energy, reduce costs, protect the environment in long-term operation. 

·         Corrosion resistance of a 3LPE coated steel is very strong.

·         Resistant to Cathodic Disbandment

·         Has High Performance and Extended Life Cycle

·         This Pipe has a service of 30-50 years long.

·         High strength epoxy. PE absorbent and hot melt adhesive softness, etc. have high corrosion reliability.

Layers of Coating

The 3LPE Coated pipes have 3 Layers of Coating.

·         Layer 1:  The First layer is of fusion bonded epoxy, which protects pipe from corrosion when needed.

·         Layer 2:  Layer of Copolymer Adhesive who has a natural bonding with the inner layer and the top

·         Layer 3:  Polyethylene Coating which helps the pipe to avoid any physical damage

3LPE Coated pipes used for transmission of oil and gas as it can withstand a temperature higher than the other pipes. It can withstand varied temperatures from dry land desserts to underwater pressures, hot temperatures to cold winters. The 3-layer coating help withstand all weather conditions and polyethylene coating helps withstand physical damage.

Advantages of 3LPE Coating Pipes

1.    Durable Lifetime

3LPE coated steel pipe has a service life for above 50 years. It is because 3LPE coating has good stability and anti-aging performances, which works under normal temperature and pressure conditions.

2.    Corrosion Resistance

The elements of PE structure stability are high. So, we can use it to prevent corrosion from natural gas, liquefied petroleum gas, artificial gas, and other chemical subjects. And it needs no secondary anti-corrosion equipment. The chemical of soil does not produce any effects on the steel pipe using 3LPE coating.

3.    Flexibility

3LPE coating is a kind of soft and flexible material, it breaks after prolong 5 times longer. It is easy to bend without damage. 3PE coating steel pipe can bypass steel pipe and reduce the fees of installation.

4.    Safe and reliable connection way

3LPE coating steel pipe mainly uses hot melt and fused connection, which connects the interface and pipeline as a whole. There is no water and gas leakage in this coated steel pipe.

5.    Light and easy to move

3LPE Coated pipe is light in weight. It only accounts 1/8 weight of steel pipe. Because of its characteristics of softness and corrosion resistant properties, it is easy to move, and easy to bend. Welding process of this pipe coating is convenient and fast.
