PRONAL pipe shutters

... plug highly pressurized Nuclear, Onshore, Offshore & Gas pipelines for inspection, test, or maintenance operations. These pipe plugs systems also ensure the buoyancy of jackets or pipes. Other ...

... Pronal anti-pollution stoppers are permanently installed inside the pipes. These patented systems are mounted on the upper section of the pipe and do not hinder the water flow. An inflation hose ...

... designed to rapidly and permanently plug pipes in the event of accidental pollution. The rapidity of this response can be attributed to a system of pneumatic stoppers which can be remotely inflated. The diameter of the ...

On the first hand, Operators greatly appreciate uni-plug stoppers when they are called upon to intervene in pipelines on nuclear sites. These low-pressure inflatable stoppers are effectively capable of preventing any ...

... remained open in the event that leaks are identified on the stopper or if the primary pipeline’s drains have ruptured. Our THPGV pipe plugs have been studied and developed in close collaboration with EDF. They are the ...

... stoppers for steam generator replacement, therefore having the role of plugging the primary pipes. Biological protection measures can be implemented and the tips of pipes can now be safely decontaminated ...

EDF is responsible for determining the hydraulic test bubbles used for ABP / ACO pipelines (secondary circuit). The preferred technique for achieving this is the installation of high-pressure pneumatic stoppers. It ...

Radiation protection is one of the primary concerns in a nuclear power plant. Progress is being made on a yearly basis in terms of the doses that may be received, notably thanks to the processes that enable this dose to be reduced at ...

... plate heat exchangers during chemical cleaning operations. Furthermore, the ONC stoppers can be remotely installed in the pipes using a rod and a cradle to prevent the stopper from being damaged by any abrasive surfaces ...

Inflatable oval stoppers are used to plug oval pipelines (egg shape pipelines) and sections of pipes. These inflatable stoppers are also a perfect solution for water or air tightness testing, being compliant ...
