External FBE Coating Equipment,Maneuverable PP Coating Equipment For Steel Pipe
INTRODUCTION
3PE coating line is to make anti-corrosion of kinds of steel pipes, such as single layer FBE, double layer FBE, double layer PE, double layer PP and 3PE.
The line includes systems of steel pipe transportation, surface disposal, dust catching, pipe heating, electrostatic spraying, coating, water cooling, edge cutting, hydraulic and pneumatic device, detecting and electric controlling system.

Description:
3PE anti-corrosion coating production line means the steel pipe is protected by three layer to prolong the life of use from 5-10years to 50-100years.
First layer is Fusion bonded epoxy layer (FBE> 100µm), the second layer of adhesive (AD) 170 ~ 250µm, the third layer of polyethylene (PE) 2.5 ~ 3.7mm. Present we can made the machinery for diameter range Φ159 ~ Φ1220.
3PE steel pipe outer coating has a high mechanical strength, excellent electrical insulation performance. The merits include high degree of mechanization, process parameters stable, not pollute the environment, etc. In recent years, the intensive of the pipeline corrosion engineering has been widely used.
3pe have Long-term corrosion resistance
FBE components have excellent adhesion to steel, providing excellent long-term corrosion resistance and protection for pipelines operating at moderate temperatures.
If desired, low application temperature (LAT) FBE can be selected as a primer to ensure low preheating conditions and long-term integrity of high strength steels (X80 or higher)
In addition, 3LPE systems have excellent cathodic stripping resistance, reducing the life cycle cost of cathodic protection

The technological processes employed by Huashida Machinery for the 3LPE coating of steel pipes involve a series of meticulous steps designed to ensure the highest level of quality and durability. Here's a detailed overview of the process:
- Upload Pipes:
- The process begins with the loading of the steel pipes onto the production line. This step ensures that the pipes are positioned correctly and ready for processing.
- Pipes Screw Conveyor:
- Once loaded, the pipes are transported through the production line using a screw conveyor. This efficient system gently moves the pipes forward, allowing for continuous and uninterrupted processing.
- Rust Removal via Intermediate Frequency Heating:
- To ensure a smooth and even coating, it's crucial to remove any rust or impurities from the pipe surface. This is achieved through intermediate frequency heating, which raises the temperature of the pipe surface to effectively burn off rust and contaminants.
- Epoxy Powder Coating:
- Following rust removal, the pipes are coated with an epoxy powder primer. This layer acts as a corrosion-resistant barrier, providing a strong foundation for the subsequent coatings.
- Outer Layer Solidification & Polyethylene Coating:
- Next, the pipes undergo the application of the outer layer, which consists of a solidified coating and a polyethylene layer. The solidification process ensures that the coating adheres firmly to the pipe surface, while the polyethylene layer provides additional protection against corrosion and wear.
Throughout this process, Huashida Machinery employs state-of-the-art equipment and rigorous quality control measures to ensure that every pipe is coated to the highest standards.
