5 Key Advantages of Bonna Pipe RCCP for Jacking & Microtunneling Project

1. Large Diameter Manufactured up to 4,000 mm in diameter for high flow capacity

2. Durability
Durable and reliable, ensuring a lifetime of dependable service

3. Simplified Construction
Jacked in a single operation straight or in curve

4. Low head loss
Smooth, with low head loss characteristics for low-cost performance

5. Custom-made solution
Custom-designed for the project needs and configuration

 

1. Large Diameter
  • Bonna Pipe RCCP is manufactured up to 4,000 mm in diameter
  • Water pipelines and industrial plants use and circulate large quantities of water that needs large-diameter pipe
  • Large diameters deliver cooling water with desirable velocities, lower friction losses, and therefore lower pumping costs
2. Durability

Environment conditions

  • The RCCP pipeline withstands full vacuum conditions
  • The protection of steel by concrete is permanent, therefore no need for maintenance
  • The external reinforced concrete compressive allows for jacking or microtunneling method
  • Bonna pipe concrete inner wall does not require any specific protection against abrasion thanks to its high strength & compactness
3. Simplified Construction
  • Bonna Pipe RCCP is jacked in one single operation thanks to the steel cylinder embedded in reinforced concrete pipe (no need for casing)
  • Bonna Pipe RCCP can be designed for jacking installation in curve
  • Bonna Intermediate Jacking Station allows to reduce number of pits
  • Comprehensive design review and preliminary plan & drawing integrate technical discussion to comply with conditions at construction site
4. Low Head Loss
  • Roughness Coefficient “k”=0.0001m  corresponds to the internal lining of the Bonna pipelines RCCP
  • The manufacturing and installation processes for Bonna Pipe RCCP result in pipelines with smooth surfaces across the joints between adjoining pipe units
  • The concrete or mortar lining does not deteriorate with age when flowing full
5. Total Custom-made Solution

Before execution of the contract, Bonna Pressure Pipes’ design and engineering office helps customers to optimize their system and works with you for all the technical aspects.

During the performance of the contract, the design and engineering office works out all the technical documents required for the project. In particular:
– The bills of materials and piping arrangement drawings for the pipes and special fittings for manufacturing and for laying
– Detailed drawings of the equipment and/or accessories supplied
– Calculations notes
– The erection manual and instructions on the protection systems to apply on site
