聚乙烯管道热熔接头冷焊缺陷的微波检测和真密度测试研究
Microwave Inspection and True Density Measurement for Cold Weld Defect in Thermo-fusion Welds of Polyethylene Piping
摘要
Abstract
Microwave scanning and true density techniques were employed to investigate the cold weld de-fect existing in the thermo -fusion welds of polyethylene (PE) piping.The thermo-fusion welds without defects were firstly inspected by microwave scanning .The resultant microwave scanning images were taken as the references .Then the thermo -fusion welds containing cold weld defects formed under different welding conditions were inspected , and the corresponding scanning images were recorded .The welding problems that lead to the cold weld defects can be distinguished by analyzing the scanning images .True density tests were conducted for different thermo -fusion welds ,the results of which confirm the effective-ness and reliability of microwave scanning in detecting the cold weld defects in the thermo -fusion welds of PE piping .关键词
