What is the Bonna Pipe RCCP?
Mr Aimé Bonna was a French Engineer and entrepreneur that invented the Reinforced Concrete steel Cylinder Pipe (RCCP) in 1894.
Mr Aimé Bonna was a French Engineer and entrepreneur that invented the Reinforced Concrete steel Cylinder Pipe (RCCP) in 1894. The Bonna Pipe RCCP as a concrete pipe with an embedded steel cylinder is composed of:
- A steel core made of rolled steel plates welded lengthwise or helically with welded end-rings
- A steel reinforcement cage made by helical winding of a steel wire at a constant pitch
- An inner and outer concrete wall casted in one single operation highly vibrated and compacted
Optimized Materials for the Bonna Pipe RCCP
The Bonna Pipe RCCP design results from the optimum combination of steel and concrete characteristics & performances. PT. Bonna Indonesia implemented EN-639/EN-641 Standards equivalent to AWWA C300.
"Bonna Pipe RCCP is the proven pipe material with over 120 years of experiences and references worldwide!"

Low Head Loss
Bonna Design Office uses the Colebrook-White Formula for hydraulic calculation with roughness coefficient of k=0.0001 m that corresponds to the internal lining of the Bonna pipelines cast in rigid metallic moulds or poured with spin process.
This "k" represents our products characteristics, as delivered, factory made, and laid in accordance with our technical notices.
Experience has shown that, for pipelines with an internal cement-based lining applied according to modern techniques, it is appropriate to take k = 0.0001 m.
This coefficient for k merely reflects a hydraulic behaviour that has been observed and quantified empirically. Some generic studies are available and private test, performed on achieved project, confirm this assessments.
