There is no need for maintenance inspection. An outer reinforced concrete wallProtecting the steel cylinder from external aggressive agents soil, underground water table, and taking the stresses due to backfill and external dead and live loads. It does not only sell standard products from a catalogue but saboa premium solutions according to each customer specific requirements.

Bonja balance thus created between concrete and steel is stable and durable. Corrosion of the metallic components, Erosion of the concrete walls, Damages due to the weather.

Any type of prefabricated concrete products. Typical offer includes not only simple concrete elements but generally combines other non-concrete materials i. The bonha project design department provides: Longitudinal compressive strengthIn case of installation by jacking or microtunnelling, the external reinforced concrete compressive strength will be used.


Resistance to pressureLauris water supply France The steel core characteristics are determined so as to resist the maximum working pressure and the factory testing pressure. Le Bugey nuclear power station, dia. A French company specialized in precast concrete products. Bonna RCCP pipes have been a reference solution for industrial and engineering clients with proven and reliable performance and several thousand references for over years on a worldwide basis.


This pipeline is still in service. Pipe jackingThis technique makes it possible to instal pipes with diameters up to mm underground.

Bonna Indonesia has successfully been diversifying into other non-pipe precast concrete elements ballast blocs, railway sleepers. Hydroelectric plant Switzerland Lauris Water supply dia.

This value that enables one to calculate the headlosses according to Colebrooks formula, is that of the best inner surface quality of the pipes presently produced reinforced concrete, cast iron, steel,GRPPVC, etc. Operations performed by divers. BONNA has thus adjusted its to mm dia. A double concrete coating placed: ER flexible type of joints and SL welded type of joints are used, depending on the diameter and the site conditions.

Minimum digging operations in the sea bottom: Positioning and sinking of one pipeline section Sea-water intake, dia. Home Documents Bonna Sabla concrete pipes. Sea-water cooling system for refinery – La Mde France Underwater pipeline, dia.

At the rear of the microtunnelling machine, a string of pipes is pushed ahead in the same way as in pipejacking. Optimized materialsA welded steel cylinder ReinforcementProviding resistance to exterDesigned to withstand the maximum working pressure including possible water hammer guarantees absolute and immediate watertightness of the pipeline and contributes to the pipeline load resistance. Subsea special Folkestone United Kingdom Clarinet for pumping station Tricastin power station France x x mm wye Koreimat power station Egypt Specifications and Quality AssuranceFlanged adaptor with anchor bars, dia.


Golfech nuclear power station, dia.

Measurements taken in the inlet pipelines of Saut hydroelectric plant in France confirm the characteristic value, K, of catalovue. Jointing of sections underwater by means of ER joints. ER joints for easier connections.

The pipeline shall resist all the phenomena likely to impair its initial capacities and to gradually destroy the performances of its components; these phenomena may be the following ones: Demonstrated durability with over years of proven performance creating precast concrete solutions.

Bonna Indonesia is not only a producer of high quality prefabricated concrete elements but is with your company from the initial design to the end of your PROJECT. Continuous towing of the stringsSte offshore outfall, dia. Arzew Natural Gas Liquefaction complex, dia.

Maximum safety with regard to floating risks: This sbala is enhanced by the high compactness of concrete obtained by high frequency vibration, centrifugation Floating of sections to their sinking position.

Excavating is performed by drilling machines or by full-face shields. Protection against abrasion and high hydraulic gradientBecause of its high strength and compactness, BONNA pipe concrete inner wall does not require any specific protection against abrasion caused by the usual carried fluids.

Durability in cata,ogue kind of waterFolkestone subsea outfall, dia. Bonna Sabla belongs to Consolis, the largest European company in prefabrication with more than factories.

Resistance to vacuum conditionsThe pipeline shall withstand full vacuum conditions water-hammer, empty pipeline, sudden emptying
