In - Depth Analysis of the Differences between FBE and 3PE Production Lines Zengqiyun's Professional Insights

With 21 years of profound expertise in the FBE field, Zengqiyun has established a unique leadership position in the industry and won the high trust of customers. Since 2024, we have successfully cooperated with major FBE customers in Algeria and Canada, providing them with high - quality services.

During this process, our production lines and configurations have been further upgraded. Currently, the installation and commissioning time of the new production lines can be rapidly shortened to within 9 days, which has earned high praise and a good reputation from international customers.

Next, we will share in detail the concerns and common questions of FBE customers. In the pipeline anti - corrosion industry, FBE (Fusion Bonded Epoxy) and 3PE (Three - Layer Polyethylene) are two common anti - corrosion processes, and their corresponding production lines also have many differences. Structurally, FBE has only one layer, while 3PE has three layers. FBE is fused epoxy powder, which mainly protects the pipeline from chemical corrosion. 3PE, on the basis of FBE, adds the processes of adhesive spraying and polyethylene material winding, greatly enhancing the anti - corrosion performance of the coating and the service life of the pipeline. In terms of the production process, the FBE production process is relatively simple, while the 3PE production process is more complex.

The first step of 3PE production is sandblasting or shot blasting derusting, which aims to remove surface impurities and enhance the adhesion of the anti - corrosion layer. After that, the steel pipe is hoisted to the winding station. The second step is to heat the steel pipe through medium - frequency electric heating to enhance the adhesion and viscosity of the epoxy powder. The third step is to spray the bottom - layer epoxy powder, that is, the FBE layer.

The fourth step is to roll - coat the second - layer adhesive, which is used to connect the epoxy powder and the outer - layer polyethylene and prevent the coating from falling off. The fifth step is to wind the third - layer polyethylene PE material. The polyethylene's corrosion resistance and wear resistance protect the steel pipe. The sixth step is to spray water on the steel pipe for cooling and heat dissipation. Finally, the 3PE - wound steel pipe is moved to the beveling machine position, the weld is ground for on - site welding, and then the steel pipe is removed. In terms of production line equipment configuration, the 3PE production line has many more key devices than the FBE production line. For example, the 3PE extrusion equipment includes adhesive extruders and plastic extruders, and each device has different models and parameters. Take a 3PE production line suitable for steel pipes with a diameter of φ86 - 630mm and a length of 9 - 12 meters as an example. It consists of multiple systems such as shot blasting derusting equipment for the outer wall of steel pipes, intermediate - frequency heating power supply, epoxy powder electrostatic spraying equipment, 3PE extrusion equipment, hydraulic and conveying equipment, water - cooling equipment, groove equipment, and electrical control of the production line. Each system is equipped with corresponding professional equipment, and these devices cooperate closely to complete the 3PE anti - corrosion production process. Zengqiyun is always committed to providing customers with professional and efficient pipeline anti - corrosion production line solutions.
