高温合金GH536无缝矩管是一种具有中空截面,周边没有接缝的长条矩形钢管。由于现在还没有高温合金无缝矩管检测方法和检测标准,为了矩管的质量得到有效控制,根据矩管生产加工过程中可能出现的缺陷,结合无损检测方法原理,在矩管半成品时用水浸式超声波检测,成品用涡流检测。并结合金相试验分析,可以得出,此种方法适合高温合金GH536无缝矩管的检测。
Superalloy GH536 seamless rectangular tube is a kind of steel tube with a hollow section and no seams along its length direction.Because there is no testing method and standard for this tube,in order to control the quality of the tube,on the basis of possible defects in the process production,combined with non-destructive testing methods,the seamless rectangular tube is tested by immersion ultrasonic testing when in the semi-finished condition and the finished tested with eddy current testing for the effective control of the tube quality.The analysis of metallography of the tube indicates that it is feasible for the testing of superalloy GH536 rectangular tube.
