Spiral Wound Lining: Repair of a DN1000 Pipeline Beneath the Bogotá Metro
Due to the project's unique location, the complexity of the construction increased, and our products were designed to ensure the successful repair of the pipeline while effectively addressing the challenges posed by the surrounding traffic environment.
Project Background
On May 2, 2025, we provided key spiral wound equipment and materials to our customer involved in a pipeline repair project located beneath Bogotá's new metro line. Due to the project's unique location, the complexity of the construction increased, and our products were designed to ensure the successful repair of the pipeline while effectively addressing the challenges posed by the surrounding traffic environment.

Project Challenges
The project faced several challenges:
Complex Traffic: The surrounding area was busy with heavy traffic, requiring strict control during construction to avoid impacting the progress of the metro's construction.
Time Constraints: Due to traffic conditions, construction could only occur during specific time windows, adding to the complexity of the project.
Pipeline Specifications: The required pipeline was DN1000, with a length of 25 meters, necessitating completion within a limited timeframe.
Solutions
To address these challenges, we developed a detailed construction plan and provided on-site guidance and training. The construction team optimized their approach in the following ways:
Efficient Construction: By carefully scheduling construction activities, we ensured the pipeline repair was completed within 5 days.
On-Site Guidance: We offered professional on-site construction guidance to help the team quickly adapt to the construction environment and improve efficiency.
Training Support: We provided comprehensive training for the construction personnel to ensure they were familiar with the use of our materials and equipment.
Advantages of Spiral Wound Repair
The spiral wound repair technology demonstrated several advantages in this project:
Water-Working Capability: The construction process had low requirements for internal water flow, allowing for easy operation even under water conditions.
Fast and Reliable: The repair process was quick and safe, with components prefabricated in the factory and wound into pipes on-site, minimizing the influence of external factors and ensuring efficiency.
Good Ductility and Toughness: The liner was suitable for repairing varying diameters, bends, misalignments, and irregular-shaped pipes, and could be used in areas with frequent external loads and poor geological conditions.
Improved Water Flow Capacity: The smooth inner wall of the repaired pipe effectively enhanced water flow capabilities.
Wide Applicability: This technology can be used for structural repairs of large pipes and box culverts, as well as pipes made of reinforced concrete, PVC, and other materials.
No Pollution: The construction process did not involve chemical reactions, avoiding pollution and other damage, ensuring environmental friendliness.
Adaptability to Complex Environments: The technology is suitable for construction in various complex geographical settings and for long-distance pipeline repairs.
Project Outcomes
Through careful planning and execution, the project was completed successfully, with the pipeline repair seamlessly integrated with the metro construction schedule. Our professional services not only enhanced construction efficiency but also ensured the project's safety and reliability.

Conclusion
Through our successful collaboration with the our customer, we have demonstrated our ability to provide high-quality pipeline solutions in complex environments. We look forward to contributing our expertise and experience to more projects in the future.
