Bridge Galvanized Metal Corrugated Pipe Prestressed Metal Bellows
Specification:
Material: Q195,Q235B, Q345
Size: From ID 40mm to 137mm
Thickness: From 0.25mm to 0.5jmm
Prestressed concrete bridge with corrugated metal pipe is used for road / rail bridge engineering, slope anchor prestressed spiral corrugated pipe, as a novel pore-forming material, it has not afraid of acid and alkali corrosion, good sealing, no seepage, leakage of plasma, ring stiffness, fear crushes, easily transportable storage storage advantages.
Appearance of product quality, structure, size, ring stiffness, local lateral loads, flexibility and other technical indicators, in line with national standards GB/T9647-2003, JT/T529-2004 transportation industry standards, our products passed the national authority in the form of inspection.
Prestressed concrete bridge with corrugated metal pipe with impermeability, pressure, high strength, good flexibility, to ensure the quality of construction. Shorten the duration and other characteristics have been widely used in a variety of large and medium bridges; senior Span Building; dams, nuclear power plants and other projects.

Prestressed metal bellows Performance:
A rigid test: anti-concentrated load 0.75KN or uniform load 1.5KN, the radial deformation ≤ 0.1d.
2, impermeability test: irrigation or water-cement ratio of 0.5 grout 30 minutes without leakage, leakage of slurry.
3, the tensile test: the wall without axial tension 5KN damaged.
4, anti-pull test: buried in the concrete pullout of anchor bolts designed to anchor pullout design pullout resistance 2.3 times or more.
5, bending experiment: curvature radius of curvature of the 30d, the non-leakage, leakage of slurry.
I produced the prestressed metal bellows (prestressed metal spiral) quality to meet Ministry of Transportation industry standard "prestressed concrete bridge with metal bellows" JG225-2007 requirements, has been widely used in highway bridges, railway bridges, water conservancy construction , electricity and other national key projects.
