- 摘要:
- 针对加氢裂化装置工艺管线数量大,高温、高压管线集中,规格繁多的特点,阐述了无损探伤应根据管径大小及焊缝所处的位置采用不同的透照方式,以提高拍片合格率。同时对γ射线、超声波探伤、渗透探伤的有关现场操作、防护等问题做了论述。
Pointing to the. features of great number, high temt?erature. high pressure, of the concentrated proccssins pipeline with various types in the hydrocraeking unit, this paper proposes that nodestructive detection should be earricd out with different ways of X一ray test aeeording to the diameter of pipe and poaitim of welding seats in urdcr to raise qualification rate of then it discusses some problems on in一situ operations and protection for γ--ray detecing,ultrasonic wave detecting and osmotic detecting and thus solves the complicated problems about detecUng tcsL in engineering.1991,6(6): 36-41 收稿日期：1991-5-30参考文献：
