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.

Mud Wiper Seal

Mud Wiper Seals are circular lip seals designed to prevent mud rising from the seafloor. Acting as an effective “anti-mud” barrier, they prevent all impurities entering the legs of offshore platforms.

These non-inflatable toric seals are used to prepare grouting operations. They prevent mud from penetrating the void between the internal diameter of the platform leg and the external diameter of the anchor pile.

The mud wiper seal provides a mud barrier when the jacket is set on the seabed and avoids mud rising after pile driving.

Mud wiper seals are designed according to :

• Leg ID
• Pile OD

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.

Inflatable Jack for Transformer Winding - VTR

The VTR inflatable jacks allow the adjustment of the height of the windings of the transformers. Indeed, during the assembly of the transformer, and at the end of the winding drying phase, it is sometimes necessary to adjust the height of the windings.

When they are empty, the lifting bags are thin and flexible. It is then very easy to slide them between the windings. Once inflated with air, they gently lift the coil without deforming it. The operator can insert or remove the shims to adjust the height of the coil.

This transformer winding adjustment system is an alternative to the traditional hammer wedge. It not only saves time but also prevents damage to the coil.

This low-pressure air lifting bag can be inflated from an air compressor, with a pressure of 0.5 bar. However, it can also be inflated from a vehicle exhaust outlet. Therefore, the system is completely autonomous. Many accessories are available to ensure the pressurization.

Its low weight, its handling handles, and its designed markings facilitate the transport and the installation of the low-pressure air lifting bag. For an even greater stroke, it is possible to superimpose cousins.

Assembled by hot vulcanization, it is resistant to many aggressions: abrasion, friction, nature of the ground, … Indeed, as a real pneumatic jack, the CBP is indispensable on sand, earth or mud. For example, it is an essential tool for removing mud from a vehicle.

In the range of inflatable lifting cushions dedicated to the pneumatic lifting of vehicles, there is also the stack bag or the high-pressure air lifting bag.
