标准范围

本文件描述了用于输送流体的聚乙烯对接熔合（BF）接头的相控阵超声波检测（PAUT），包括管道对管道、管道对配件和配件对配件的接头。该文件提供了一种测试，通过该测试，可以检测BF接头中是否存在缺陷，如空隙、夹杂物、缺乏融合、错位和颗粒污染。该文件仅适用于没有超声波屏障的聚乙烯管道和配件。本文件还提供了程序鉴定的要求和人员鉴定的指导，这对于本试验技术的应用是必不可少的。本文件还涵盖了聚乙烯高炉接头的设备、试验准备和性能、适应症评估和报告。本文件未涵盖验收标准。

This document describes the phased array ultrasonic testing (PAUT) 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, whereby the presence of imperfections such as voids, inclusions, lack of fusions, misalignment and particulate contamination in the BF joints can be detected. The document is only applicable 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 the application of 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.
