This quality assurance device tests the ductility of polyethylene pipe fusion joints in a safe, quick manner. The Guided Side Bend Tester is for use with 1″ to 7″ pipe walls. 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.
