3PE Anti-corrosion steel pipes shall comply with the relevant standards, primarily using polyethylene and high-density polyethylene, with a Vicat softening point of not less than 110 ; The thickness of the external anti-corrosion coating is determined in accordance with German standards and consists primarily of low- and medium-density polyethylene. 3PE The impact strength of the anti-corrosion coating has been significantly improved. It is explicitly stipulated that… 3PE The mechanical strength and weather resistance of the anti-corrosion coating have increased the sampling frequency for joint peel strength. 3pe Anti-corrosion pipelines are typically manufactured through processes including roll forming, high-frequency welding, extrusion, cooling, sizing, and flying‑saw cutting. The front end of the production line is equipped with a storage loop, while the rear end features a steel pipe turning rack. Based on the yield‑effect and proximity‑effect phenomena, a strong localized thermal effect is generated at the opening of the tube blank during butt welding, enabling rapid heating to the temperature required for welding and facilitating intergranular bonding via roller pressure. 3PE Anti-corrosion steel pipes feature high circulation capacity and low construction costs. The inner pipe walls are lubricated, resulting in relatively minimal scale buildup. PE The ratio of the equivalent roughness inside to outside is that of steel pipes. 1/20 . Under the same diameter, length, and pressure, PE The flow capacity of the pipe is X percent greater than that of a steel pipe. 30 Around this level, its economic advantage is quite substantial.

In 3PE In the practical application of anti-corrosion steel pipes, three materials are blended into a single composite and, after processing, firmly bond with the steel pipe to form an excellent anti-corrosion coating. The manufacturing processes are generally categorized into two methods: the winding method and the rotary-die coating method. Manufacturing 3PE The main equipment of anti-corrosion steel pipe production includes: a steel pipe buffer platform, a pipe‑pulling device, a traction machine, a pipe‑threading machine, a high‑pressure gun launcher, a maintenance platform, a transmission line, a steel pipe preheating furnace, a shot‑blasting machine, a main maintenance platform, a bifurcated steel pipe return transmission line, quick‑feed roller sets, quick‑exit rollers, and a maintenance platform, among others. The anti-corrosion steel pipe production line is suitable for single‑layer applications. FBE , double-layered FBE , double-layer polyethylene, double-layer polypropylene, and 3PE Anti-corrosion treatment for steel pipes. Pipe diameter processing. 104 mm  (4 ') Small, processed pipe diameter 1600 mm  (63 ') Large, processing capacity 350 m²/h The above. The production line comprises a steel pipe conveying system, a surface treatment system, a pipe dust‑removal system, a steel pipe heating system, an electrostatic spraying system, a coating system, a water‑cooling system, an end‑cutting system, hydraulic and pneumatic systems, an inspection system, and an electrical control system, among others. 3pe Anti-corrosion coatings combine the excellent impermeability and superior mechanical properties of epoxy resins and polyethylene. To date, they are globally recognized as the preferred coating for steel pipe corrosion protection, delivering outstanding performance and reliability, and have been successfully deployed in numerous projects.
