Other mains

We love a challenge at QUALM. We may specialise in fire water mains, but if your mains contain something else, we can help too. We will examine the situation thoroughly, deal with it and deliver the solution. We always offer a total solution, irrespective of the material, the connections and the scale.

Steam pipes

We laid a steam mains for DSM in Geleen. It was not our core business, but we have engineers who have the expertise to work with any type of piping. They had to take several factors into account. The mains needed to be underground while allowing enough space for the pipes to expand because of the high temperature. They also needed to withstand high pressure, and we needed to place a condensate drain. In the end, we placed a steel-in-steel system in which the inner pipe had the space to expand while the outer pipe provided protection. The space between the pipes is a vacuum, maximising the insulation.

Our engineers found the best solution and our technicians ensured that the work was done properly and safely.

City heating

More and more blocks of flats, hospitals, universities and industrial sites are being heated with the residual heat from industry. We laid a gas and water mains system at TU Delft and relocated the city heating system. We used a pre-insulated steel pipe with a PE outer shell. The joints were soldered and insulated. The TU Delft did not need to hire in a separate company for the city heating. We made it easy, convenient and cost-effective for TU Delft.
