Product Overview
Our fully automatic prestressed metal corrugated pipe making machine is professional manufacturing equipment for producing metal corrugated pipes reserved for prestressed concrete. Adopting 0.23‑0.4×78±0.5mm galvanized steel strip or cold‑rolled steel strip as raw materials, this corrugated pipe production equipment completes the whole production workflow automatically: washing → guide frame → forming roller → winding die head → edge trimming & crimping → pipe forming → cutting.
Compact in overall structure, this spiral metal duct machine features easy‑to‑operate human‑machine touch screen control system. It can work well both in scattered construction sites and centralized factory workshops, bringing stable continuous pipe output for your production project.
Core Advantages
✅ High Efficiency & Material Saving
Easy for operators to master. High finished pipe yield rate. Compared with conventional units, our bridge corrugated pipe making machine can save up to 12% raw materials, greatly boosting your overall production capacity.
✅ Superior Finished Pipe Performance
Pipes manufactured by this post‑tension corrugated tube equipment own excellent acid & alkali resistance, reliable sealing performance without water leakage. The finished duct comes with high ring stiffness, low friction coefficient, anti‑aging and anti‑electric corrosion property. It keeps intact against vibration rod impact, squeezing and stepping during construction. Transportation, storage and daily maintenance are effortless.
✅ Stable Product Compliance
Critical technical indicators of finished pipes, including appearance quality, structural dimension, ring stiffness, local transverse load and flexibility, fully meet industry standard requirements. Consistent output quality reduces product rejection rate.
Application Scope
This prestressed metal corrugated pipe machine produces spiral prestressed metal corrugated pipes widely applied for highway bridges, railway bridges, ports, docks, water conservancy and other post‑tension engineering projects. The finished ducts also satisfy hole‑forming demands for slope anchoring and other construction scenarios.
