News: Advance Your Pipeline Protection with Our State-of-the-Art 3PE Anti-Corrosion Pipe Coating Line
Qingdao Haosaite Plastic Machinery Redefines Durability and Efficiency in Pipe Coating Technology
[Qingdao, China] – [2025,28，Oct] – Qingdao Haosaite Plastic Machinery, a leading manufacturer of industrial coating machinery, today announced its flagship 3PE (Three-Layer Polyethylene) Anti-Corrosion Pipe Coating Line. This fully automated, high-output production solution is engineered to deliver superior pipeline protection for the most demanding applications in the oil, gas, and water transmission industries.
The integrity of underground and subsea pipelines is paramount. Corrosion is the single greatest threat to their lifespan and safety. Our advanced 3PE coating line applies a robust, multi-layer shield that effectively combats chemical, electrochemical, and mechanical degradation, ensuring pipeline integrity for decades.
Unmatched Coating Quality Through Precision Engineering
Our 3PE coating line integrates a seamless, sequential process to guarantee a perfect bond between the steel pipe and the protective layers:
Advanced Surface Preparation: The line features a high-performance shot blasting system that thoroughly cleans and profiles the pipe surface, achieving a pristine Sa 2.5 standard for optimal adhesion.
Precision Heating: An induction heating system brings the pipe to an exact, controlled temperature, ensuring perfect conditions for the subsequent coating stages.
Fusion-Bonded Epoxy (FBE) Layer: An electrostatic powder spray system applies a uniform, pinhole-free FBE layer. This serves as the primary, high-performance anti-corrosion barrier.
Co-polymer Adhesive & PE Extrusion: The line utilizes twin extruders to simultaneously apply a copolymer adhesive layer and a dense polyethylene top layer. This combination creates a formidable shield against mechanical damage and moisture ingress.
Controlled Cooling & Inspection: A calibrated water cooling system solidifies the coating, while integrated inspection stations ensure every meter of pipe meets the highest international standards (e.g., ISO 21809-1, DIN 30670).
Key Features & Benefits for Your Business:
Fully Automated Control: A centralized PLC and HMI system minimizes human error, ensures consistent quality, and optimizes production efficiency.
High Production Capacity: Designed for high output, our lines can be configured to produce 30,000 to 100,000+ tons of coated pipe annually, maximizing your ROI.
Superior Coating Performance: The final product offers exceptional resistance to cathodic disbondment, impact, abrasion, and a wide range of soil chemicals.
Dual Coating Capability: Many of our lines are designed to also produce 3PP (Polypropylene) coatings, ideal for high-temperature operating environments.
Eco-Friendly Operation: A closed-loop powder recovery system captures and recycles over 99% of excess epoxy powder, reducing waste and operational costs.
"A reliable pipeline starts with a superior coating. Our 3PE coating line isn't just machinery; it's a commitment to safeguarding critical infrastructure worldwide," said [Spokesperson's Name], [Title] at [Your Company Name]. "We provide our clients with the technology to produce the most durable, cost-effective anti-corrosion pipes on the market, giving them a competitive edge in their projects."
This robust production solution is ideal for pipe manufacturers and large-scale project developers looking to bring coating operations in-house or upgrade their existing capacity.
