Direct Sales from Manufacturer: Precast Beam Concrete Corrugated Pipe with Inner Diameter φ90mm, φ70 Galvanized Steel Strip Corrugated Pipe

Pre-stressed galvanized corrugated pipe is a type of metal conduit commonly used in pre-stressed concrete structures, primarily for the protection and guidance of pre-stressing tendons (such as steel strands or reinforcement bars). Below is a detailed introduction to this type of pipe:

1. Main Features

• Material: Typically made from galvanized steel strip, offering excellent corrosion resistance and mechanical strength.
• Structure: Spiral corrugated design, providing good flexibility for easy bending and installation.
• Application: Mainly used in post-tensioned pre-stressed engineering, such as bridges, buildings, Direct Sales from Manufacturer: Precast Beam Concrete Corrugated Pipe with Inner Diameter φ90mm, φ70 Galvanized Steel Strip Corrugated Pipe large concrete components, etc.

2. Main Advantages

• Strong Corrosion Resistance: The galvanized layer effectively prevents rust, extending service life.
• Excellent Flexibility: The corrugated structure allows for easy bending, adapting to complex construction environments.
• High Compression Resistance: Capable of withstanding pressure during concrete pouring, preventing deformation.
• Good Sealing Performance: Prevents cement grout from penetrating Direct Sales from Manufacturer: Precast Beam Concrete Corrugated Pipe with Inner Diameter φ90mm, φ70 Galvanized Steel Strip Corrugated Pipe, protecting pre-stressing tendons from corrosion.

3. Application Fields

• Bridge Engineering: Used in pre-stressed structures such as box girders and T-beams.
• Building Structures: Such as long-span slabs, stadiums, etc.
• Hydraulic Engineering: Such as dams, culverts, and other structures requiring pre-stressed reinforcement.

4. Construction Considerations

• Pre-installation Inspection: Ensure the pipe is free from damage and the galvanized layer is intact.
• Fixing Method: Requires specialized brackets for fixation, Direct Sales from Manufacturer: Precast Beam Concrete Corrugated Pipe with Inner Diameter φ90mm, φ70 Galvanized Steel Strip Corrugated Pipe to prevent displacement during concrete pouring.
• Connection Method: Typically uses sleeve connections or specialized joints to ensure sealing.
• Grouting Requirements: Grouting is necessary after construction to fill the pipe voids and protect the steel strands.
