Emergency pipe plug operating manual
How to use THE EMERGENCY PIPE PLUGCompliance with the instructions below is imperative to avoid any risk of accidents or injuries with emergency pipe plug use. The emergency pipe equipment uses high pressure nitrogen cylinders (200 bars) and therefore requires use in strict compliance with the indications and safety rules below. Our control pannels are delivered equipped and pre-set in the factory or on site by our technicians. NEVER change the pressure of the Pressure Regulator, as this may cause damage to the equipment or burst the obturator, with all the consequences that this would entail (risk of serious injury and material damage). Adjustments and work on the system must only be carried out by qualified Musthane personnel.
INFLATION– Remove the padlock from the shut-off valve. – Open the shut-off valve on the side of the cabinet to supply power to the circuit board, – Break the glass with the glass breaker hammer, – Open the release valve or press the mushroom button (depending on the model). – The deflation key or valve must be closed (depending on the model), – Once the light is activated, the balloon inflates.
DEFLATECAUTION: Before any deflation, it is mandatory to check that there is no more water in static upstream of the emergency plug, otherwise the equipment may be damaged. – Close the trigger valve or deactivate the mushroom button, – Open the deflation valve, – Allow air to escape completely, – Wait for the emergency plug to return to its rest position in the pipeline, – Visually check that the obturator is properly seated in the upper part of the pipeline, – Close the shut-off valve, – Check that sufficient pressure remains in the cylinder to allow re-inflation, – Return the system to its initial position by repositioning the padlock on the shut-off valve and locking it. – Replace the glass of the mushroom button (to be provided as a spare part, if necessary, please consult us). Note: Plan to change the compressed nitrogen bottles for the next inflation and deflation.
How to Control emergency pipe plug?Every 3 month, check the : – general condition of the boxes, plate, hoses, regulators, plugs, visually check the cleanliness of the pipe and have it cleaned/uncluttered if necessary (the plug will not be able to seal a congested pipe, the sealing is done on the entire periphery of the pipe). – pressure of the cylinders, (the pressure of a cylinder must be between 170 bar and 220 bar). – plate for leaks. At least once a year – Carry out an inflation and deflation in order to check the correct operation of all the equipment. Special precautions – It is strictly forbidden to modify the settings of the control boards WITHOUT authorization from MUSTHANE. This could result in the bursting of the emergency plug, which could cause damage to property or even personal injury. – It is strictly forbidden to intervene upstream or downstream of the pipe: During the inflation or deflation of the obturator and once the plug has been inflated. – After each use, it is imperative to check that the equipment is still operational (check the stopper, the load of the bottles, etc…). CAUTION: Make sure to close and disconnect all nitrogen cylinders before working on the equipment.
emergency pipe stopper recommendationsConcerning the emergency pipe plug, it has been designed for the precise diameter of the pipe that you have communicated to us; we formally advise you not to use it for another pipe without prior authorization from Musthane. Compliance with the instructions below is imperative to avoid any risk of accidents or injury with pneumatic plugs.
- Validate that the range of use of the plug is in accordance with the Ø of the pipe.
- Respect the inflation pressure (PG)
|Ø canalisation mm||PG max bar|
- Calculate the pressure that must be supported by the inflatable stopper and never exceed the maximum allowable back pressure.
- Determine if there are requirements for special heat or aggressive product resistance.
- Always inspect and clean inflatable stoppers and their equipment before and after use.
- Clean the pipe before installing the emergency pipe plug.
- Never stand in front of the obturator while it is in operation.
- Never pressurize an inflatable air plug.
- Do not transform or modify the inflatable stoppers or their accessories, otherwise there is a risk of bursting.
- When using the inflatable stopper, always consider the safety of the user and of the persons present at the site.
