SaskPower Shand Cooling Water Piping
Each pipe had a steel liner with 2" of reinforced concrete on the inside and 6" outside.
Nutana Machine won the subcontract to manufacture the steel liners.
The pipes were manufactured to the AWWA Spec. (American Water Works Association)
The Specification required that each piece be pressure tested to 75% of yield.
A mandrel was engineered to minimize the amount of water needed to accomplish the test.
