Zum Deformation ResistanceThe reinforced concrete provides the pipeline with the transverse rigidity required for resisting backfill loads and live loads. Fitting by means of hydraulic jacks. BONNA has thus adjusted its to mm dia. ER flexible type of joints and SL welded type of joints are used, depending on the diameter and the catalgue conditions. Partenaires Gobert Bending strengthIf the pipe is used as a span pipeline, the combined effect of concrete and steel provides it with the required longitudinal rigidity. It consists in driving the pipe into the ground by means of jacks.

Le Bugey nuclear power station, dia. Any type of prefabricated concrete products. 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. Floating of sections to their sinking position.
Arzew Natural Gas Liquefaction complex, dia. The largest Indonesian group involved in precast concrete products for construction and civil works. Bonna Indonesia has successfully been diversifying into other non-pipe precast concrete elements ballast blocs, railway sleepers.
Bonna Sabla belongs to Consolis, the largest European company in prefabrication with more than factories. Buried conditions Aboveground conditions Submerged conditions including sea-water Submerged pipeline Folkestone, dia.
Bending strengthIf the pipe is used as a span pipeline, the combined effect of concrete and steel provides it with the required longitudinal rigidity. This pipeline is still in service. Continuous towing of the pipeline sections. ER joints for easier connections. BONNA has thus adjusted its to mm dia. Sea-water cooling system for refinery — La Mde France Underwater pipeline, dia. This value that enables one to calculate the headlosses according to Colebrooks formula, is that of the best inner surface quality catalpgue the pipes presently produced reinforced concrete, cast iron, steel,GRPPVC, etc.
Deformation ResistanceThe reinforced concrete provides the pipeline with the transverse rigidity required for resisting backfill loads and live loads.
Partenaires Hydroelectric plant Switzerland Lauris Water supply dia. At the rear of the microtunnelling machine, a string of pipes is pushed ahead in the same way as in pipejacking. 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: Maximum safety with regard to floating risks: Typical offer includes not only simple concrete elements but generally combines other non-concrete materials i.
Post on Nov views. Jointing of pipeline sections together by means of SL welded joints. Golfech nuclear power station, dia. Fitting by means of hydraulic jacks. Minimum digging operations in the sea bottom: Buried pipeline Water supply pipeline, dia. 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.
Durability in any kind of waterFolkestone subsea outfall, dia. 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. Home Documents Bonna Sabla concrete pipes. Positioning and sinking of one pipeline section Sea-water intake, dia.
Bonna Indonesia provides, when required, tailored-made engineered solutions not commodities. There is no need for maintenance inspection. Geneva Oil port Switzerland Paramo Bajo irrigation pipeline, dia. This effect is enhanced by the high compactness of concrete obtained by high frequency vibration, centrifugation The welded joints totally transmit the stresses sustained at changes of direction to the pipeline.
Continuous towing of the stringsSte offshore outfall, dia. In this case, the best possible protection is secured by the concrete coating. 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.
Longitudinal tensile strengthIn case of a pipeline being pulled into place, the steel cylinder tensile strength will be used. The balance thus created between concrete and steel is stable and durable. This technique can be applied to small bore non man-entry pipes.
