本文件描述了用于输送流体的聚乙烯电熔(EF)承插接头的相控阵超声波检测(PAUT)。该文件提供了一种测试，通过该测试可以检测电熔承窝接头中缺陷的存在，例如空隙、导线错位、错位、管道穿透不足、颗粒污染、冷熔合和缺乏熔合。该技术仅适用于没有超声波屏障的聚乙烯电熔插座配件。本文件还提供了程序确认要求和人员确认指南，这对于本试验方法的应用至关重要注1:在出版时，仅有将PAUT用于尺寸在90 mm至710 mm之间的聚乙烯（PE80和PE100）电熔插座接头（SDR 11和17）的经验[7][8][9][10][11][12][13]。注2循环测试表明，PAUT是增强电融合接头完整性评估的可行方法【16】。注3本文件不适用于未刮削管道的检测。这种检测可以通过简单的目视检查来实现，前提是采用机械刮削工具。

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 methodNOTE 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)^{[7][8][9][10][11][12][13]}.NOTE 2 Round robin testing has shown that PAUT is a viable method for enhancing the integrity assessment of electrofusion joints^[16].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.
