The Challenge
Stadtwerke Emmerich was faced with the challenge of drilling three new wells for drinking water production. The d 225 polyethylene (PE) supply pipes had to be connected to the existing PE raw water pipe d 450 SDR 17. The challenge for the customer was to realize this in the most cost-efficiently and timesaving as possible. The standard solution was to install a T-piece with two pipe couplings. However, this was both material and time-consuming. In addition, the supply pipe would have had to be shut down and emptied, which would have been quite risky. Also due to the tight time frame, the use of T-pieces and the associated decommissioning of the raw water pipeline was ruled out.
The Solution
The solution to this challenge was offered by the new SA UNI d 400/450 with the outlet dimension d 225. The decisive advantage of this product is the enormous time savings, the smaller space requirement and the lower costs compared to T-pieces coupler. The combination of lower costs, easier installation and greater flexibility makes SA UNI a valuable innovation in the field of pressure pipe systems.
The Realisation
In addition to the molded parts themselves, Aliaxis' construction site service was used. This included the appropriate technical equipment such as clamping and drilling equipment, scraper chain and comprehensive on-site instruction. After only 3.5 hours, all the saddles were fitted and welded - a time frame that would not have been possible with T-pieces.
The Conclusion
The example of Stadtwerke Emmerich clearly shows the advantages of SA UNI from Aliaxis. Thanks to the new saddles, the project was completed in just a few hours without interrupting the drinking water supply – an impressive time saving compared to traditional methods. In addition, the reduced space requirement has led to smaller excavations and therefore further resource savings.
Not only are costs effectively saved, SA UNI also convinces with a reduced overall CO2 footprint, which is achieved through lower material- and reduced energy consumption.
