渗透检测在换热器管板上的应用和影响因素分析

Penetration testing in the heat exchanger tube sheet of the application and impact factors

本文通过对换热器管板角接接头的结构特点出发,分析了该种接头所适合的渗透检测方法,然后分别从制造焊接工艺、缺陷性质尺寸、渗透检测工艺及操作上对渗透检测灵敏度的影响因素进行了分析,从而对管板角接接头的渗透检测过程进行有效的实际控制,对于管板角接接头的检测灵敏度具有重要的指导意义。

Based on the heat exchanger tube plate corner joints in the structural characteristics, analyzes the types of connectors are suitable for infiltration detection methods, and then separately from the manufacture of welding process, defects in size, penetration testing process and the operation of the penetration test factors affecting the sensitivity of the analysis to tube plate corner joints of the penetration testing process for effective practical control of the transfer tube plate joints for the detection sensitivity of important guiding significance.
