ER flexible type of joints and SL welded type of joints are used, depending on the diameter and the site conditions. A French company specialized in precast concrete products.

Bonna Indonesia has successfully been diversifying into other non-pipe precast concrete elements ballast blocs, railway sleepers. It consists in driving the pipe sabbla the ground by means of jacks.


There is no need for maintenance inspection. 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.

It cataloghe not only sell standard products from a catalogue but made-to-measure premium solutions according to each customer specific requirements. Deformation ResistanceThe reinforced concrete provides the cataligue with the transverse rigidity required for resisting backfill saba and live loads. Arzew Natural Gas Liquefaction complex, dia.

Post on Nov views. Typical offer includes not only simple concrete elements but generally combines other non-concrete materials i. This effect is enhanced by the high compactness of concrete obtained by high frequency vibration, centrifugation Jointing of pipeline sections together by means of SL welded joints.


This pipeline is still in service. ER joints for easier connections. Excavating is performed by drilling machines or by full-face shields. Positioning and sinking of one pipeline section Sea-water intake, dia. This technique can be applied sahla small bore non man-entry pipes.

BONNA has thus adjusted its to mm dia. As heading proceeds, the soil is excavated from inside and upstream the string of pipes.

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. Buried pipeline Water supply pipeline, dia. Minimum digging operations in the sea bottom: Corrosion of the metallic components, Erosion of the concrete walls, Damages due to the weather. The welded joints totally transmit the stresses sustained at changes of direction to the pipeline. Durability in any kind of waterFolkestone subsea outfall, dia.

At the rear of the microtunnelling machine, a string of pipes is pushed ahead in the same way as in pipejacking.

Hydroelectric plant Switzerland Lauris Water supply dia. Longitudinal compressive strengthIn case of installation by jacking or microtunnelling, the external sabls concrete compressive strength will be used. Onshore assembling of pipes into sections Folkestone offshore outfall, dia. 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.


Pipe jackingThis technique makes it possible to instal pipes with diameters up to mm underground. Measurements taken in the inlet pipelines of Saut hydroelectric plant in France confirm the characteristic value, K, of 0.

In this case, the best possible protection is secured by the concrete coating. Floating of sections to their sinking position.

Operations performed by divers. Cataloghe by means of hydraulic jacks.

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. Bonna Sabla belongs to Consolis, the largest European company in prefabrication with more than factories. Installation by bottom tow Onshore assembling of pipes into strings by means of SL welded joints. Pressure watertightness of the cstalogue components systematic tests throughout the manufacturing stage.
