Pressure Testing of Pipelines

Accurate pressure measurements in extreme conditions. Water distribution networks are the foundation of modern infrastructure. Huge volumes of water need to be efficiently transported over long distances from the source to the consumer. Leaks not only lead to the loss of a valuable resource but can also disrupt the soil structure, resulting in costly restoration work. Therefore, the integrity of pipelines is a critically important factor for an efficient and economical water supply system.

Preparation for hydrotesting

At the stage of manufacturing new pipelines, a mandatory leak test is conducted, the results of which are recorded in the accompanying documents. The main control method is pressure testing, during which the pipe must withstand a pressure of 16 bar for 60 minutes. Special manometers allow specialists to monitor the readings in real time. A sharp drop in pressure indicates the presence of defects that can be fixed before the system is put into operation.

Testing equipment

After the tests are completed, the program automatically generates a clear graph based on data received from the sensors. KELLER Pressure provides the necessary software free of charge.

For testing, a reliable, easy-to-use device is required that can autonomously record not only pressure but also temperature (since its fluctuations affect the readings in the pipeline).

Water quality and pressure drop monitoring

The Swiss company BRINER-AG, specializing in servicing the construction industry, has been successfully using autonomous KELLER Pressure LEO Record data loggers for such tasks for many years.

“LEO Record is so intuitive that even temporary staff can operate it after a brief instruction,” notes Fabian Lenz, Head of Sales at BRINER-AG.
