Product Description

The 3PE Anti Corrosion Coating Pipe Production Line Machine is another game-changer in the anticorrosion and insulation pipe industry. With this 3PE Anti Corrosion Coating Pipe Production Line, you can produce pipes with exceptional internal and external anti-corrosion coatings, offering an added layer of protection to your pipes. The 3PE Anti Corrosion Coating Pipe Production Line uses advanced technology to coat steel pipes with Polyethylene (PE), making them resistant to moisture, acids, and other harmful elements that could cause damage.


The 3PE Anti Corrosion Coating Pipe Production Line outer anti-corrosion layer of 3PE steel pipe is an anti-corrosion structure composed of a bottom layer of epoxy powder, an intermediate layer of adhesive, and an outer layer of polyethylene. 3PE Anti Corrosion Coating Pipe Production Line has high mechanical strength, excellent electrical insulation properties, a high degree of mechanization of the production line, and relatively stable process parameters. With the advantages of not polluting the environment, 3PE Anti Corrosion Coating Pipe has been widely used in major pipeline anti-corrosion projects in China in recent years. 


The three-layer structure polyethylene anti-corrosion layer combines the excellent properties of epoxy coating and extruded polyethylene anti-corrosion layer, combining the interface properties and chemical resistance properties of the epoxy coating with the mechanical protection properties of the extruded polyethylene anti-corrosion layer These advantages are combined to significantly improve their respective performance. Therefore, 3PE Anti Corrosion Coating Pipe is very superior as an outer protective layer for buried pipelines. According to relevant information, three layers of PE can extend the service life of buried pipelines to 50 years. Currently, it is considered an excellent external anti-corrosion technology for pipelines. In our country, 3PE Anti Corrosion Coating Pipe has been first used in oil and gas systems.


3PE Anti Corrosion Coating Pipe Production Line Process Flow:

The outer wall of the steel pipe is first derusted to clean the rust on the surface of the steel pipe, and then the steel pipe is transported to the intermediate frequency heating place for heating through a spiral conveyor line. After the steel pipe is heated, it is sprayed with epoxy powder, wrapped with adhesive and polyethylene, and the wrapped steel pipe is Then cooling spray is performed to reduce the temperature, and finally both ends of the steel pipe are beveled and polished.


3PE Anti Corrosion Coating Pipe Production Line generally consists of 3 layers of structure:

The first layer of epoxy powder (FBE>100um)

The second layer of adhesive (AD)170~250um

The third layer of polyethylene (PE) 2.5~3.7mm


The 3PE Anti Corrosion Coating Pipe Production Line is an anti-corrosion structure composed of a bottom layer of epoxy powder, an intermediate layer of adhesive, and an outer layer of polyethylene. 3PE Anti Corrosion Coating Pipe Production Line has strong corrosion resistance, high mechanical strength, excellent electrical insulation properties, a high degree of mechanization and technology. The 3PE Anti Corrosion Coating Pipe Production Line parameters are relatively stable and it does not pollute the environment. 3PE Anti Corrosion Coating Pipe has been widely used in pipeline anti-corrosion projects at home and abroad.

Requests for questions(RFQ)

What is 3PE coating?

3PE, which stands for "Three-Layer Polyethylene," is a common coating used to protect steel pipes from corrosion and extend their service life, especially in applications where the pipes are exposed to harsh environments, such as in the oil and gas industry.


How do you protect pipeline from corrosion?

Coatings are one of the primary means of protection for a pipeline. Polyguard's RD-6 pipe corrosion protection is a coating system that is used on buried and submerged pipelines. Once a UV-protective coating such as RD-6 UV Overcoat is used in conjunction with RD-6, it can be used above ground.


What type of coating is used on pipelines?

Epoxy coatings for oil and gas applications offer excellent resistance to high temperatures, chemicals and corrosion. Current protective coating technology for oil and gas pipelines is recognized to have both technical and economic disadvantages.


What pipe coating prevents corrosion?

Internal coating solutions, such as FlexSleeve and fusion bonded epoxy, can prevent the corrosive elements from damaging the pipe surfaces. These coated layers act as barriers against hydraulic friction losses, pig wear, and build-up of pyrophoric dust in pipes.


What is PE coating on pipe?

PE coated steel pipe is a group of pipes coated with polyethylene on metal parts. There are different types of PE coated carbon steel pipe products in use. Use basic 3 layers. LDPE, LDPE Super Seal and HDPE are the three types. These depend on the form of polyethylene used in the coating.


What is 3 layer polyethylene coating?

Three Layer Polyethylene/ Polypropylene coating Systems (3LPE/PP), a multi layer coating composed of three functional components: a high performance fusion bonded epoxy (FBE) followed by a copolymer adhesive and an outer layer of polyethylene/polypropylene which provides tough and durable protection.


What is the best pipeline coating?

Epoxies With Fusion Bonding

This is one of the best types of pipeline coating. Fusion bonded epoxies are single-component, heat-curable, thermosetting epoxy. FBEs apply to heating parts in the form of a powder (10-40 mils) that quickly gels from liquid to solid.
