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

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. Measurements taken in the inlet pipelines of Saut hydroelectric plant in France confirm the characteristic value, K, of 0.
Durability in any kind of waterFolkestone subsea outfall, dia. Pipe jackingThis technique makes it possible to instal pipes with diameters up to mm underground. This effect is enhanced by the high compactness of concrete obtained by high frequency vibration, centrifugation Continuous towing of the pipeline sections.
The in-house project design department provides: Floating of sections to their sinking position.
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: 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.
Sea-water cooling system for refinery – La Mde France Underwater pipeline, dia. There is no need for maintenance inspection. Among the technologies and services available: Buried pipeline Water supply pipeline, dia. Longitudinal compressive strengthIn case of installation by jacking or microtunnelling, the external reinforced concrete compressive strength will be used.
Resistance to vacuum conditionsThe pipeline shall withstand full vacuum conditions water-hammer, empty pipeline, sudden emptying The welded joints totally transmit the stresses sustained at changes of direction to the pipeline. Home Documents Bonna Sabla concrete pipes. 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.
Typical offer includes not only simple concrete elements but generally combines other non-concrete materials i.

Minimum digging operations in the sea bottom: ER joints for easier connections. Bonna Indonesia has successfully been diversifying into other non-pipe precast concrete elements catqlogue blocs, railway sleepers. 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.
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.
The largest Indonesian group involved in precast concrete products for construction and civil works. Deformation ResistanceThe reinforced concrete provides the pipeline with the transverse rigidity required for resisting backfill loads and live loads. In this case, the best possible protection is secured by the concrete coating.
Fitting by means of hydraulic jacks. Jointing of pipeline sections together by means of SL welded joints.
