What is 3LPE coating, and how does it protect pipes?

3LPE coating, or three-layer polyethene coating, is a protective layer applied to pipes to enhance their durability and resistance to corrosion. It consists of three layers: a fusion-bonded epoxy (FBE) base layer, an adhesive layer, and a polyethene outer layer. The FBE base layer provides excellent adhesion to the pipe surface, creating a strong bond. The adhesive layer ensures a seamless transition between the FBE and outer polyethene layers.

The polyethene outer layer is a barrier against moisture, chemicals, and mechanical damage, protecting the pipe from corrosion and extending its lifespan. This coating system provides a robust defence against environmental factors, such as soil conditions, chemicals, and abrasive substances, significantly reducing pipe deterioration and maintenance requirements risk. Additionally, the 3LPE coating offers good impact resistance and thermal insulation properties, making it suitable for various applications in industries like oil and gas, water distribution, and infrastructure development.

What are the advantages of using 3LPE-coated pipes compared to other coatings?

Using 3LPE-coated Pipes offers several advantages over other types of coatings. Firstly, the three-layer polyethene coating provides superior corrosion protection, minimizing the risk of pipe degradation and extending the service life of the pipes. That is particularly beneficial in environments where the pipes are exposed to aggressive substances, such as chemicals or moisture. The fusion-bonded epoxy (FBE) base layer ensures excellent adhesion to the pipe surface, creating a strong and durable bond. In contrast, the outer polyethene layer is a barrier against corrosion-causing elements.

Secondly, 3LPE-coated pipes are known for their robust mechanical properties. The coating offers high impact resistance, which helps protect the pipes from damage during transportation, handling, and installation. Additionally, the coating provides thermal insulation properties, reducing heat loss or gain in fluid transportation systems.

Carbon Steel 3LPE External Coating Pipe Manufacturing Process

Rolling and welding

Firstly, the carbon steel strips are made to gone through various quality checks and are trimmed at edges. They are then fed to the tubes mill by carbon steel pipe manufacturers in India. The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process. The scraps and inside weld bead are removed instantaneously by the Tibo machine. In this way, rolled pipes and tubes are formed.

The cleaning and heating phase

The rolled High Pressure Seamless Pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the SS tubes and pipes are straightened and subjected to pickling for removing scales from the surface.

Cold- drawing process

In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

Finishing process

The drawn-out tube or alloy pipe is then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine is used to do the marking on the finished pipes or tubes. The pipe or tube is marked with grade of material, size, heat number and the stamp of third party inspection before passing on to carbon steel pipe exporters. The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch. There are numerous numbers of carbon steel pipe applications, these pipes and tubes are used thereafter for.
