Prestressed metal corrugated pipes offer excellent versatility, interchangeability, compatibility, and ease of use.

Performance of Prestressed Metal Corrugated Pipes

(I) Characteristics of Prestressed Metal Corrugated Pipes

Lightweight, high stiffness, excellent sealing, and strong adhesion and pull-out resistance.

(II) Application Scope of Prestressed Metal Corrugated Pipes

Prestressed metal corrugated pipes for post-tensioned prestressed reinforced concrete bridges; prestressed metal corrugated pipes for reinforced concrete hollow slabs; metal corrugated pipes for anchor bolt reserved holes; embedded pipes for building and structural walls and foundation pipelines.

(III) Performance of Prestressed Metal Corrugated Pipes

1. Rigidity Test: Radial deformation ≤0.1d under a concentrated load of 0.75KN or a uniformly distributed load of 1.5KN.

2. Seepage Resistance Test: No water leakage or slurry leakage after 30 minutes of filling with water or cement slurry with a water-cement ratio of 0.5.

3. Tensile Test: No damage to the pipe wall under an axial tensile force of 5KN.

4. Pull-Out Test: The pull-out resistance embedded in concrete is more than 2.3 times the design pull-out resistance of anchor bolts.

5. Bending Test: No water leakage or slurry leakage when bent to a curvature radius of 30d.

Prestressed metal corrugated pipes are widely used in various large and medium-sized bridges, high-rise long-span buildings, dams, nuclear power plants, and other projects due to their seepage resistance, pressure resistance, high strength, flexibility, and ability to ensure construction quality and shorten project duration.
