Making a connection in the middle of the night at -20°C is not easy. Especially if you have to connect HDPE SDR11 to HDPE SDR 32.5 you are in a world of trouble. But not if you use the MULTI/JOINT® 3000 Plus.
The Situation at Fort Erie
The Town of Fort Erie is a small border town with 30,000 inhabitants and a rich history, located some 30 kilometres south of Niagara Falls in Ontario, Canada.
Near one of the town's main roads, a 41-year-old sewage pipe needed to be diverted for a water treatment plant.
The old DN400 pipe needed a new valve group. The old age of the pipe, however, was not the only problem. It was an HDPE SDR 32.5 pipe, which is very thin-walled. The customer needed to connect this HDPE SDR 32.5 pipe to an HDPE SDR 11 and demanded a guaranteed connection.
Advice from Sandale & GF Piping Systems
Sandale’s team worked with the Town of Fort Erie and explored the best ways to connect the prefab unit to the old pipe. Welding was not an option when it came to connecting HDPE SDR 32.5 to SDR 11.
Glen Steele, sales manager at GF Canada, advised using a “new” product which can mechanically make a restraint connection between different pipe diameters: a MULTI/JOINT® 3000 Plus, DN400 (16”). At the time it was a relatively new product in Canada.
Executing the Plan
In order to cause as little inconvenience as possible, the project engineer came up with the following idea:
fully prepare and build the valve group, which will then only have to be connected;
the valves will be installed in an HDPE SDR11 pipe; and
the connection would be made during the night.
Simple Installation, Even at Extremely Low Temperatures
The installation was done by Sandale in the middle of the night at -20°C feeling even colder by the wind.
The installation went well, nonetheless. After the old pipe was sawed off, an insert was installed on both sides. Then the MULTI/JOINT® 3000 Plus DN400 was lowered by its lifting eye and installed on the pipe.
Finally, the prefab unit was lowered into the trench with a crane and connected to the existing pipe with the MULTI/JOINT® 3000 Plus couplings.
Successful Scoop in Canada
Both the contractor and Sandale’s customer were more than satisfied with this first experience with the MULTI/JOINT® 3000 Plus couplings. And next time they certainly will not hesitate to use these products in similar projects!
