Emergency Pipe Plug Diameter Greater Than 1000mm - OFR
The OFR is an inflatable emergency pipe plug with a diameter greater than 1000 mm. It has been specially designed to plug pipes with large diameters. The diameter of the pipe defines the inflation pressure. It is dedicated to the reliable and permanent sealing of pipes.
In the event of a disaster, the emergency pipe plug inflates and acts as a valve that retains the polluting products. Once confined, these liquids are pumped or diverted to a retention basin. The sealing balloon thus stops the propagation of chemical products or fire water, eliminating any risk of pollution.

PIPE TEST PLUG- OTR
Pronal’s pipe test plug OTR is designed to test the tightness of inspection wells that are found in waste-water systems. Flexible and light, you can easily integrate it in the sewerage network. Moreover, its execution is very fast.
Whatever the diameter of the pipe, the height of the sealing balloons is 200 mm. This allows a simple and fast use in narrow spaces.
Thanks to a double-walled fabric and a hot vulcanization in the autoclave, the pipe test plug allows a perfect seal. It also offers a high resistance to wear and tear and therefore a long service life.
In addition, the pipe plug is equipped with through walls for pressurization, intended for manhole tightness tests.
In the range of inflatable pipe plugs dedicated to sanitation, there is also the standard inflatable pipe plug OPL.
