It does not only sell standard products from a catalogue but made-to-measure premium solutions according to each customer specific requirements. Operations performed by divers. 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. Durability in any kind of waterFolkestone subsea outfall, dia.

Among the technologies and services available: In this case, the best possible protection is secured by the concrete coating. 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.

Installation by bottom tow Onshore assembling of pipes into strings by means of SL welded joints.

The balance thus created between concrete and steel is stable and durable. 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. Protection against abrasion and high hydraulic gradientBecause of its high strength asbla compactness, BONNA pipe concrete inner wall does not require any specific protection against abrasion caused by the usual carried fluids.

Bonna Sabla belongs to Consolis, the largest European company in prefabrication with more than factories.


Deformation resistance test in Span pipe – River-crossing in Arcachon France Cavalaire mm dia. As heading proceeds, the soil is excavated from inside and upstream the string of pipes.

There is no need caralogue maintenance inspection. The largest Indonesian group involved in precast concrete products for construction and civil works.

Universal Control Setup

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. Longitudinal compressive strengthIn case of installation by jacking or microtunnelling, the external reinforced concrete compressive strength will be used.

This value that enables one to calculate the headlosses according to Colebrooks formula, is that of the cafalogue inner surface quality of the pipes presently produced reinforced concrete, cast iron, steel,GRPPVC, etc. BONNA has thus adjusted its to mm dia.

This effect is enhanced by the high compactness sbla concrete obtained by high frequency vibration, centrifugation Aboveground pipeline Rhne Poulenc plant, dia.

The welded joints totally transmit the stresses sustained at changes of direction to the pipeline.

Bending strengthIf the pipe is used sab,a a span pipeline, the combined effect of concrete and steel provides it with the required longitudinal rigidity.

Continuous towing of the stringsSte offshore outfall, dia. ER flexible type of joints sablaa SL welded type of joints are used, depending on the diameter and the site conditions.

A French company specialized in precast concrete bonan. Bonna Indonesia provides, when required, tailored-made engineered solutions not commodities. Fitting by means of hydraulic jacks. Longitudinal tensile strengthIn case of a pipeline being pulled into place, the steel cylinder tensile strength will be used. 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.

It is thus possible to avoid the use of bulky and costly thrustblocks at changes of direction. It consists in driving the pipe into the ground by means of jacks. Buried pipeline Water supply pipeline, dia. Positioning and sinking of one pipeline section Sea-water intake, dia. Pressure watertightness of the steel components systematic tests throughout the manufacturing stage. 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.

Maximum safety with regard to floating risks: Post on Nov views. Jacking pipe – Madrid Spain 6Properties and advantagesResistance to external stressesResistance to impact loadingDuring and after laying, the pipeline may be submitted to shocks and blows that are likely to damage its catalogye, and even to destroy its physical integrity. Home Documents Bonna Sabla concrete pipes.

Sea-water cooling system for refinery – La Mde France Underwater pipeline, dia. 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: Waste water delivery pipe at Colombes factory France – dia. Demonstrated durability with over years of proven performance creating precast concrete solutions. Corrosion of the metallic components, Erosion of the concrete walls, Damages due to the weather.

This technique can be applied to small bore non man-entry pipes. At the rear of the microtunnelling machine, a string of pipes is pushed ahead in the same way as in pipejacking.
