We offer deflection gauges, line stringer parachutes, proving rings, line stringers and ventilators, and the rope reels you need to pull the testing equipment through. The testing equipment is offered in various sizes to meet your project’s specific needs. Our mandrel sewer test equipment is sourced from trusted brands like Oatey and Hurco to ensure the job gets done right.

Learn more about our mandrel and deflection testing equipment in our FAQ section below.

How do I choose the right sized mandrel for a deflection test?

As a general rule, the outside diameter of the mandrel you need should be determined by comparing it against the pipe’s internal diameter, as certified by the manufacturer.

What is a proving ring used for in deflection testing?

Proving rings are used prior to deflection testing to ensure the mandrel/deflection gauge you are using is the right size.

Is deflection testing required for all pipe materials?

No; generally, deflection testing is only necessary for testing flexible pipe materials such as PVC, HDPE or polypropylene, as these can flex or deform due to soil pressure. Rigid materials like concrete typically do not require deflection testing.
