Engineering prestressed metal corrugated pipe equipment

Product Brief

This specialized pipe‑making machine is developed for prestressed concrete construction. It is applied to produce prestressed metal corrugated pipe, which serves as reserved duct for post‑tension projects. With mature double‑wave crimping forming technology, the unit finishes strip feeding, rolling, edge locking and cutting continuously. Reliable operation ensures good structural performance of finished pipes for bridge and civil engineering applications.

Main Advantages

High Efficiency & Material Saving: Easy commissioning and operation with high pipe‑output capacity. It can save 12% raw‑material consumption compared with traditional processing solutions and lower overall production cost.
Superior Finished Pipe Quality: Excellent corrosion resistance and sealing performance. High ring stiffness and good flexibility, perfectly matching requirements of post‑tension duct. Convenient for on‑site butt joint, transportation and storage.
Stable & Reliable Performance: All core technical parameters comply with industry standards, stable output of qualified corrugated pipes for large‑scale engineering projects.

Application & Usage

This equipment manufactures spiral metal corrugated pipes specially for prestressed works. Finished pipes are widely adopted in highways, railway bridges, ports & docks, water‑conservancy projects, slope anchoring and other civil‑engineering scenarios, mainly used as prestressed concrete reserved channel.

Production Process

Raw steel strip → Cleaning tank → Guide frame → Forming rolls → Winding die head → Edge trimming & crimping → Pipe forming → Cutting

The workflow realizes continuous rolling for double‑wave corrugation, and forms firm interlocked seam via edge‑pressing technology to ensure pipe structural stability.

Working Raw Material

Galvanized steel strip or cold‑rolled steel strip, dimension: 0.23‑0.4 × 78±0.5 mm.

Qualified steel strip shall have uniform thickness and good ductility to guarantee crimp‑locking effect of corrugated pipe.
