微波扫描法检测聚乙烯管道热熔接头缺陷初探
Microwave Scanning Inspection of Defects in Thermo-fusion Joints of Polyethylene Piping
摘要
Abstract
The method of microwave scanning was employed to detect different types of defects existing in the thermo - fusion joints of polyethylene ( PE) piping. Firstly the thermo - fusion joints without defects were inspected by microwave scanning,and the scanning images obtained were taken as the references. Then the thermo -fusion joints containing different defects including cracks,cold weld,etc. ,were inspected and the resultant scanning images corresponding to different defects were obtained. The types of the defects can be distinguished by analyzing the scanning images. At last, tensile tests for the thermo - fusion joints were performed to confirm the effectiveness of microwave scanning in detecting the defects in the thermo - fusion joints of PE piping.关键词
