Scope
Scope: This document specifies the terms and definitions, general requirements, inspection procedures, evaluation of inspection data validity, quantification of defects, quality assessment, and inspection reports for phased array ultrasonic inspection of heat-fused butt joints of polyethylene pipes. This document is applicable to phased array ultrasonic inspection of heat-fused butt joints of polyethylene pipes with a nominal diameter of 110mm to 630mm (wall thickness of 10mm to 60mm) that comply with GB 15558.1, GB 15558.2, or other similar standards. Main technical content: This standard specifies general requirements for ultrasonic inspectors, phased array ultrasonic inspection instruments, phased array ultrasonic probes, phased array ultrasonic scanning devices, test blocks, coupling agents, scanning modes and display methods, and focusing rules. This clause is based on provisions in conventional phased array ultrasonic standards and takes into account the special requirements for the detection of non-metallic pipe joints. In particular, it stipulates that auxiliary sound beam deflectors (including liquid wedges, low-attenuation colloidal wedges, or low-sound-beam solid wedges such as polystyrene) can be installed for inspection. The standard also specifies requirements for standard test blocks, comparison test blocks, and simulation test blocks, and stipulates the selection of test block materials, curved surface inspection, and coupling agents.
