T/ZJASE 018-2022 Stress pipe corrosion ultrasonic guided wave detection (piezo-elastic method)
Abstract
Scope: This document specifies the method and defect grade evaluation for detecting the corrosion condition of pressure pipelines using ultrasonic guided waves (magnetostrictive method). It is applicable to steel pressure pipelines with an outer diameter of 38 mm to 1200 mm, a wall thickness of 0.5 mm to 60 mm, and an operating temperature of -20℃ to 200℃. Non-ferrous metal pipelines shall be implemented in accordance with this document. Main technical content: It standardizes the general steps of magnetostrictive ultrasonic guided wave technology in the detection of pressure pipeline defects and the related defect grade evaluation. Specifically, it makes detailed provisions on personnel qualifications, safety requirements, detection steps, signal evaluation, and report issuance.
