英文名称：Thermoplastic pipes for the conveyance of fluids — Inspection of polyethylene electrofusion socket joints using phased array ultrasonic testing
发布日期：2019-12
标准范围
This document describes the phased array ultrasonic testing (PAUT) of polyethylene electrofusion (EF)
socket joints used for the conveyance of fluids. This document provides a test whereby the presence
of imperfections such as voids, wire dislocation, misalignment, pipe under-penetration, particulate
contamination, cold fusion and lack of fusion in electrofusion socket joints can be detected. The
technique is only applicable to polyethylene electrofusion socket fittings without a barrier to ultrasonic
waves. This document also provides requirements for procedure qualification and guidance for
personnel qualifications, which are essential for the application of this test method
NOTE 1 At the time of publication, experience only exists on the use of PAUT for polyethylene (PE80 and
PE100) electrofusion socket joint sizes between 90 mm and 710 mm (SDR 11 and 17) .
NOTE 2 Round robin testing has shown that PAUT is a viable method for enhancing the integrity assessment
of electrofusion joints .
NOTE 3 This document does not apply to the detection of unscraped pipe. Such detection can be achieved by a
simple visual inspection, provided mechanical scraping tools are employed.
