Subsea special Folkestone United Kingdom Catalotue for pumping station Tricastin power station France x x mm wye Koreimat power station Egypt Specifications and Quality AssuranceFlanged adaptor with anchor bars, dia. 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 bona pipeline and contributes to the pipeline load resistance.
Resistance to vacuum conditionsThe pipeline shall withstand full vacuum conditions water-hammer, empty pipeline, sudden emptying Corrosion of the metallic components, Erosion of the concrete walls, Damages due to the weather. This technique can be applied to small bore non aabla pipes. Bona does not only sell standard products from a catalogue but made-to-measure premium solutions according to each customer specific requirements.
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: Continuous towing of the stringsSte offshore outfall, dia.
Fitting by means of hydraulic jacks. Waste water delivery pipe at Colombes factory France – dia.
Besides, the head-losses inside the pipeline remain low as time goes by. A French company specialized in precast concrete products. Bending strengthIf the pipe is used as a span pipeline, the combined effect of concrete and steel provides it with the required longitudinal rigidity.
ER joints for easier connections. Sea-water cooling system for refinery – La Mde France Underwater pipeline, dia.
Bonna Indonesia provides, when required, tailored-made engineered solutions not commodities. It consists in driving the pipe into the ground by means of jacks.
As heading proceeds, the soil is excavated from inside and upstream the string of pipes. Minimum digging operations in the sea bottom: Bonna Indonesia has successfully been diversifying into other non-pipe precast concrete elements ballast blocs, railway sleepers. This pipeline is still in service. A steel core made of rolled steel plates welded lengthwise or helically with welded A steel reinforcement made by helical winding of a steel wire at a constant pitch.
Buried conditions Aboveground conditions Submerged conditions including sea-water Submerged pipeline Folkestone, dia.

Demonstrated durability with over years of proven performance creating precast concrete solutions. Jacking pipe – Madrid Spain 6Properties and advantagesResistance to external stressesResistance to impact loadingDuring and after laying, bomna pipeline may be submitted to shocks and blows that are likely to damage its coating, and even to destroy its physical integrity.
There is no need for maintenance inspection. A double concrete coating placed: Post on Nov views. Any type of prefabricated 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. Bonna Indonesia is not only a producer bpnna high quality prefabricated concrete elements but is with your company from the initial design to the end of cataoogue PROJECT.

Excavating is performed by drilling machines or by full-face shields.

At the rear of the microtunnelling machine, a string of pipes is pushed ahead in the same way as in pipejacking. Jointing of pipeline sections together by means of SL welded joints. Operations performed by divers. The balance thus created between concrete and steel is stable and durable. Typical offer includes not only simple concrete elements but generally combines other non-concrete materials i. In this case, the best possible protection is secured by the concrete coating.

Cataalogue jackingThis technique makes it possible to instal pipes with diameters up to mm underground. It is thus possible to avoid the use of bulky and costly thrustblocks at changes of direction.
Among the technologies and services available: This effect is enhanced by the high compactness of concrete obtained by high frequency vibration, centrifugation Deformation ResistanceThe reinforced concrete provides the pipeline with the transverse rigidity required for resisting backfill bomna and live loads.
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.
Positioning and sinking of one pipeline section Sea-water intake, dia. Floating of sections to their sinking position. Jointing of sections underwater by means of ER joints. 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.
