630mm Ritmo All Terrain Butt Fusion Machine and accessories, including BDI (Bead Diagnostic Instrument)

Stroud is renowned for suffering with water shortages, so along with another Severn Trent Water project from Whaddon to Westrip Reservoir, CPC Civils were tasked with laying the new mains pipeline to supply Stroud.  CPC Civils wanted to show that they were working to the highest possible standards of workmanship, whilst demonstrating full traceability on the work they produced.

The Challenge

CPC Civils were awarded the project from the AMEY and Severn Trent Water Framework with work commencing in early February 2019.  When the work was awarded they were incredibly clear that they wanted to perform the job to the highest standards and ensure their growing reputation in the industry was enhanced further.

The site of the work would cover difficult terrain, and CPC Civils wanted to be able to move the welding equipment with ease across the site. They also wanted to provide evidence of their work carried out were done to the highest standards and full accountability could be recorded of the work carried out.

The Solution

PSS HIRE working alongside CPC Civils were able to offer the Ritmo 630mm All Terrain Butt Fusion Machine with 450mm and 560mm liners. This allowed CPC Civils to weld two different sizes of pipe with the same machine.  Due to the location of the project working on some steep embankments and across fields, the Ritmo product was the ideal piece of equipment for the specific nature of the site. The machine is equipped with four-wheel drive electric motors across the four heavy-duty wheels and a detachable control panel. Because the machine would be moving along the pipeline on some very challenging terrain this made the manoeuvring of the machine much easier. It is a fully automatic fusion machine, which worked out drag pressures, heat and soak timings and with the hydraulics made the alignment of the pipe a quick and easy process.

Along with the Ritmo 630, CPC Civils hired a BDI (Bead Diagnostic Instrument) to verify the quality of each weld. The BDI is able to produce real time live data by analysing the externally removed bead, so to undertake a “belt & braces” approach to the weld quality.

It removes the need to perform the manual twist back test, where the operator would have to try and twist the bead from the weld produced every 4-6 inches to check the quality of the weld. The BDI via the web portal produces a report in conjunction with ControlPoint for each weld performed. This ensured that CPC Civils were able to show AMEY and Severn Trent Water joint information from both the Butt Fusion machine and the BDI that each weld was performed to high standards. As all this was Live information, if there were any issues with the welds produced that they could be corrected quickly if required. 

"Our operatives found the use of the Ritmo machine easy to operate and move across site. The product induction provided by PSS HIRE’s SME’s ensured we were confident that our operatives were comfortable with the workings of the machine.

The BDI ensured that our reporting to AMEY and Severn Trent matched the weld data we recorded, and showed we were working to the highest standards possible."

The Results

CPC Civils were able to complete the scheme of work, whilst overcoming some serious issues with the weather and the terrain. The Ritmo was an easy piece of kit for the operators to use and manoeuvre across site making their day as easy and efficient as possible. Using the BDI in conjunction with the Ritmo machine, CPC Civils were able to show AMEY and Severn Trent Water, that the welding of the PE Pipe was to the highest possible standards and the weld data produced by the Ritmo machine and from the BDI was able to be matched up, meaning the reports from both the items of equipment could be clearly reported to the client.
