How to choose the right Pronal inflatable pipe plug ?
To select the Pronal inflatable pipe plug best suited to your needs, consider the following criteria :
- Type and size of the pipeline : Ensure the plug is compatible with the diameter and material of the pipeline to be sealed (concrete, steel, PVC, etc.).
- Pressure and operating environment : Choose a model capable of withstanding the pressure of the fluid or gas to be contained, while considering the operating conditions (extreme temperatures, chemicals, etc.).
- Sealing purpose : Determine whether you need a plug for leak testing, maintenance work, temporary repair, or leak prevention.
- Frequency and duration of use : Opt for materials and models suited for either occasional or regular use, depending on your requirements.
