Mandrel Testing

Ensure new lines have been installed properly

“Mandrel testing” or “deflection testing” is used to determine that the ovality of flexible sewer pipe meets design specification. This testing is critical to the long-term performance of PVC sewer lines being installed today.

Mandrel Design

Thuro’s light-weight aluminum deflection gauges utilize a nine-fin configuration, allowing for the passage of sewage when testing live sewers. Go + No Go proving rings are used to verify that each deflection gauge is within tolerance. Manufactured for use in The City of Calgary each ring has a unique serial number and are individually approved for use from the City of Calgary Water Resources – Research, Policy and Standards Team.
