Non-destructive testing of the welded joints between heat exchange tubes and tube sheets
Thread Content
In Chapter 11, Experiments and Inspections, of hg20584, section 11.1.1 deals with heat exchangers in which medium leakage is not allowed; the welding joints between the heat exchange tubes and the tube sheet in such exchangers can be subjected to radiographic inspection. Question: What kind of welding structure is suitable for radiographic inspection?
Any of them will do. As part of the MOODY three-party inspection, for the tube sheet welding of the heat exchangers in Yangba Phase 2 at BASF, RT sampling inspections are required
All of them can be detected, but the prices are relatively high; quotes are provided separately, and usually customers only conduct random inspections.
