Also known as “deflection testing” this testing is very important with the installation of PVC pipelines
Mandrel Testing will determine the ovality of flexible sewer pipe, it will confirm that specifications are met, and is very important in the diagnostics of the long term performance of the PVC sewer lines
Before the testing can be done, the pipelines or sewer lines need to be flushed and cleaned.
If there is any debris or sediment in the lines, it may interfere with the passing of the Mandrel/Deflection testing devices, and may falsely indicate a problem.
Mandrel testing is used to determine the deflection of the sewer pipes ensuring they meet all of the OPS specifications.
