基于超声方法的聚乙烯管材厚度和直径测量

Thickness and Roundness Evaluation of PE Pipe by Multi-Channel Ultrasonic Technique

摘要: 针对PE管的厚度、直径椭圆度等质量控制指标，研究和设计了宽频超声大口径聚乙烯(PE)管质量评价系统。提出的超声波检测方法对PE管在生产、施工及检修中提高管材的质量可信度及安全可靠性具有实际意义。

Abstract: Broadband ultrasonic testing for large diameter PE pipe was studied and designed for the quality control of its thickness and diameter. The testing system was introduced. The ultrasonic testing technologies proposed were well in assuring the reliability and credibility of PE tube production and on-site inspection.
