This quality assurance device tests the ductility of polyethylene pipe fusion joints in a safe, quick manner. This testing method places the entire wall thickness into tension and gives assurance of the ductility of joints. Operators can perform the test safely with the use of a hydraulically-powered device that puts three points of pressure on test coupons. If no gaps or breaks are present in the fusion joint after the test, the result is a passing grade. The Guided Side Bend Tester is lightweight and requires the operator to supply a planer, calipers and saw to complete the testing procedure.
