Prestressing sheathing bellows

Corrugated pipe

Introduction:Post tensioning prestressing sheathing pipe for bridges and construction industries .

size 40mm to 120mm

diameter 0.25-0.28mm

corrugated pipe is used for highway ,railway ,bridge engineering, slope .It is prestressed spiral bellows. As a new kind of ahole-forming component, it is not afraid of acid, alkali corrosion, good sealing performance, press , leakage. It is also easy to transport , deposit, custody. The qualifications such as product appearance, quality, structure, size, ring stiffness, partial lateral load, flexibility are all passed the national authoritative organization's examination.

Test result:

1,Rigid test: resistance to centralized load 0.75KN or uniformly distributed load 1.5KN radial deformation ≤ 0.1d.

2,Permeability test: irrigate slurry of water-cement ratio 0.5 , there is no leakage of water, no leakage of slurry in 30 minutes.

3,Tensile test: axial tension 5KN without wall damage.

4,Uplift experiment: buried in the concrete pullout force of the anchor bolt design pullout resistance to anti-pull bolt design force of more than 2.3 times.

5, bending experiment: bend 30d is the radius of curvature, no leakage of water, no slurry leakage.
