Crack growth tester PLT

installation

SCITEQ's Point Load tester is used for determining the resistance to slow crack growth of polyethylene pipes with external point load. The PLT system complies with PAS 1075:2009 Annex A3. PAS 1075 defines characteristics, requirements and test methods for pipes made of PE for alternative installation procedures. The PLT system consists of three main parts, namely the PLT pressure station cabinet, the PLT thermo tank and the PLT frames with the circular 4-screw point load testing unit and end closures. A pipe sample mounted with end closures is placed in the open PLT frame where the pipe sample rests on the frame. Subsequently the PLT unit is mounted on the frame and the four PLT screws are fixed on the pipe sample and adjusted. The PLT frame is ready to be emerged into the thermo tank where the pipe sample can be aired out and pressurized.
