Galvanized metal corrugated pipe

Prestressing corrugated pipes are primarily used in prestressed concrete structures to create channels, protect, and guide prestressing strands or reinforcing bars. They are commonly classified into two main categories: **plastic corrugated pipes (HDPE) and metal corrugated pipes (galvanized steel strip).

PRODUCT DETAILS

Core Applications

Forming Prestressing Ducts

Installed prior to concrete pouring, they form smooth ducts after curing, facilitating the insertion and tensioning of steel strands.

Protecting Prestressing Members

They isolate the strands from concrete, water, and chloride ions, preventing corrosion and extending the structure’s service life.

Ensuring Dense Grouting

The smooth inner walls of the corrugated pipes facilitate the subsequent injection of cement grout, ensuring that the steel strands and concrete act as a single unit under load.

Positioning and Guidance

Secures the position of prestressing tendons, ensuring accurate curves and alignment, and preventing displacement during pouring.

Typical Applications

1. Highway/Railway Bridges (Primary Application)

- Longitudinal prestressing ducts for box girders, T-beams, and hollow-core slabs

- Continuous beams, rigid-frame bridges, and bridges constructed using formwork baskets

- Wet joints on bridge decks, transverse prestressing, and vertical prestressing

2. Municipal Engineering

- Elevated bridges, interchanges, and ramp bridges

- Prestressed structures in large underground utility tunnels, subway station ceilings, and side walls

- Prestressed tank walls in large water tanks and wastewater treatment facilities

3. High-Rise Buildings and Long-Span Structures

- Long-span frame beams, transfer beams, and prestressed floor slabs

- Prestressed hidden beams in high-rise shear walls and tube structures

- Large-span roof beams for large parking garages, convention centers, and sports arenas

4. Water Resources and Special Engineering

- Sluice gates, aqueducts, and prestressed retaining walls

- Special prestressed concrete structures such as nuclear power plant containment vessels and large storage silos

Differences in the Applications of the Two Types of Corrugated Tubes

- Metal Corrugated Tubes

High stiffness and stable positioning; commonly used for straight, short strands, and vertical prestressing; frequently employed in traditional bridges.

- Plastic Corrugated Tubes (HDPE)

Low friction, excellent corrosion resistance, and more compact grouting; commonly used for long curved prestressing strands, cross-sea bridges, and highly corrosive environments; currently the mainstream choice.

Integrated Mortar Pump

The integrated design of the mixing and storage tank and pumping mechanism eliminates the need for a separate mixer. The feeding, mixing and conveying are completed in one go. It can transport cement mortar, cement slurry and grouting material, and is mostly used in small-scale grouting, repair, plastering and prestressed assisted grouting construction site scenarios.

Twin-Cylinder Slurry Pump

The dual-cylinder grouting pump uses two oil cylinders to alternately suck and discharge grout, resulting in continuous discharge without pulses, high pressure, and stable flow. Compared with the single-cylinder pump, it has higher efficiency and better pressure stabilization effect, making it the main equipment for large-scale grouting projects in roads, bridges, tunnels, mines, and foundation pits.
