Global transportation infrastructure construction has entered a booming cycle, and intelligent forming machinery represented by Prestressed Metal Corrugated Pipe Equipment has become standard supporting equipment for highway, railway and cross-sea bridge projects. Traditional semi-automatic pipe rolling devices rely heavily on manual adjustment, which leads to unstable dimensional accuracy of finished ducts and a waste rate of raw steel strips up to 12%. The upgraded full-automatic production system adopts integrated PLC control, covering the whole process of steel strip cleaning, double-wave rolling, edge locking forming and fixed-length cutting, and can process 0.23–0.4mm galvanized cold-rolled steel coils stably.
The finished prestressed metal corrugated pipe produced by the machine has excellent sealing performance without slurry leakage during concrete pouring, and its low friction coefficient effectively reduces prestress loss when threading steel strands. Unlike rigid metal pipes, the spiral structure brings strong flexibility, so it will not be punctured by vibrators in construction. Manufacturers simplify the overall layout of the unit, so the equipment can be put into use both in fixed processing factories and temporary construction sites for slope anchoring projects. Optional flat pipe molds further expand production capacity to meet the pore-forming needs of super high-rise building beam slabs.
As a core automated pipe rolling line, this set of machinery has passed international authority testing, and all indicators such as ring stiffness, transverse load and bending performance of finished pipes meet AASHTO and Eurocode standards. The optimized crimping structure cuts steel consumption per meter by 12%, which greatly reduces the comprehensive material cost of infrastructure contractors. Built-in energy-saving variable frequency motors lower power consumption by 18% compared with old models, matching the global low-carbon construction trend. At present, R&D teams are developing AI visual detection modules, which will be embedded in the forming host in 2027 to realize real-time full inspection of pipe joints and surfaces.
Market research predicts that driven by the expansion of global transportation networks, the market demand for intelligent prestress duct production equipment will maintain steady growth in the next five years. Engineering contractors prefer integrated complete production units because consistent pipe quality avoids hidden dangers of prestress attenuation caused by poor sealing of inferior pipes. With the continuous progress of cross-sea bridge and water conservancy project construction, the technical iteration of steel strip forming machine will continue to accelerate to adapt to more complex geological construction environments.
