Abstract

This document describes the time of flight diffraction (TOFD) testing of polyethylene butt fusion (BF) joints, including pipe-to-pipe, pipe-to-fitting, and fitting-to-fitting joints, used for the conveyance of fluids. This document provides a test to detect imperfections such as voids, inclusions, lack of fusions, misalignment, and particulate contamination in the BF joints. The document only applies to polyethylene pipes and fittings without a barrier to ultrasonic waves. This document also provides requirements for procedure qualification and guidance for personnel qualifications, which are essential for applying this test technique. This document also covers the equipment, the preparation and performance of the test, the indication assessment, and the reporting for polyethylene BF joints. Acceptance criteria are not covered in this document.
