Spiral Concrete Corrugated Post Tension Tube Machine
Corrugated Post-Tensioning Tube-Former Machine Specifications
Our spiral corrugated post-tensioning tube making machine is excellent for producing round corrugated ducts used in expressways, bridges, trains and large-span post-tension concrete projects. The prestressed Protection Tube Machine is suitable for both indoor and site work. With its special corrugations, the very high radial stiffness is well suited for use as former in concrete structures. Corrugated tube is also being used as culverts and forms for concrete projects, plinths and columns. On many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, schools and hospitals, the introduction of the prestressed protection tubes will make it possible to use very long spans. The reduction in weight allows large areas and fewer columns which in turn gives a technical economical advantage.
