This galvanized corrugated pipe is a key component in prestressed concrete construction, used as ducts for steel strands in highway and tunnel projects. It provides a protective, corrosion-resistant pathway for prestressing tendons, ensuring smooth tensioning and long-term durability of the structure.
Material and Specifications
Made from high-quality Q195 steel, the pipe features a galvanized surface for enhanced corrosion resistance. It has a nominal inner diameter range of 35-135mm, with wall thickness options from 0.2mm to 0.6mm. The double corrugated structure provides excellent rigidity and flexibility, while the length can be customized from 1m to 30m to meet different project requirements. Available specifications include DN35, DN40, DN45, DN50, DN55, DN60, DN65, DN70, DN75, DN80, DN85, DN90, DN95, DN100, DN105, DN110, DN115, DN120, DN125, DN130, and DN135.
Design Features
The double corrugated design offers superior structural strength and crush resistance, while maintaining flexibility for easy installation in curved or complex layouts. The galvanized coating provides excellent protection against moisture and corrosion, extending the service life of the pipe in harsh construction environments. The smooth inner surface ensures low friction during prestressing operations.
Application Advantages
These pipes are specifically designed for highway and tunnel construction, where reliable prestressed ducts are essential. The wide range of specifications allows for use with various steel strand sizes and project designs. Their lightweight yet robust construction makes them easy to handle and install on-site, reducing labor costs and improving construction efficiency.
