High-Pressure Corrugated Plastic Duct – Durable, Flexible & Engineered for Demanding Industrial Applications
Engineered for resilience and adaptability, the High Pressure Corrugated Plastic Duct is a premium solution designed to meet the rigorous demands of modern infrastructure projects. Also referred to as Prestressed Bellows flexible ducts or high-pressure corrugated tubes, this product combines superior structural integrity with exceptional flexibility—making it ideal for environments where both mechanical strength and dynamic movement are critical. Whether used in highway systems, railway tunnels, or large-scale civil engineering works, these ducts ensure reliable performance under extreme pressure conditions while maintaining optimal airflow or fluid transport efficiency.
Manufactured from high-density polyethylene (HDPE) or similar advanced polymers, each duct features a reinforced corrugated profile that enhances tensile resistance and minimizes deformation under load. With diameters ranging from 50mm to 160mm and wall thicknesses between 2–3mm, these conduits offer customizable sizing options tailored to specific project needs. Lengths are available on request, enabling seamless integration into complex installations without compromising system continuity or safety.
Key Features:
- Exceptional durability against environmental stressors including UV exposure, chemical corrosion, and temperature fluctuations
- Corrugated design promotes efficient air or fluid flow while resisting kinking and collapse
- Lightweight yet robust construction simplifies handling and installation
- Available in various standard sizes and custom lengths to suit diverse applications
- Compatible with prestressed concrete systems, anchorage components, and photovoltaic mounting solutions
This high-pressure flexible duct serves as an essential component in modern construction, particularly within pre-stressed concrete frameworks. Its ability to accommodate thermal expansion, vibration, and ground movement makes it especially valuable in elevated bridge structures, underground utilities, water conservancy systems, and industrial facilities such as steel plants and power stations. It also supports the secure routing of electrical cables, hydraulic lines, and ventilation systems across demanding infrastructural environments—from urban transit networks to remote dam projects.
Designed by Chunpeng Group, a global leader in Prestressed Steel materials with over three decades of expertise, this product reflects our commitment to innovation, quality control, and sustainable engineering practices. Our extensive portfolio includes ultra-high-tensile PC strands, galvanized and weather-resistant steel products, unbonded tendons, and specialized anchorage systems—all developed to enhance structural longevity and reduce lifecycle costs in large-scale developments worldwide.
Users consistently report improved installation speed, reduced maintenance requirements, and enhanced system reliability when integrating these ducts into their projects. Many engineers appreciate how the smooth internal surface reduces friction loss, while the external corrugation provides excellent anchoring points for securing the conduit during installation—a key advantage in seismic-prone regions or areas subject to soil movement.
Common Questions:
- What makes this duct suitable for high-pressure environments?
- Can it be used in buried utility applications?
- Is it compatible with other types of prestressed systems?
- How does its flexibility compare to rigid metal alternatives?
Yes—this duct excels in high-pressure scenarios due to its engineered geometry and material composition. It’s widely adopted in buried utility installations because of its corrosion resistance and long service life. It integrates seamlessly with prestressed anchorages, beam systems, and solar racking setups. Compared to traditional metal ducts, it offers greater flexibility without sacrificing strength, reducing the need for additional support brackets and easing transportation logistics.
