Non-destructive testing issues at the butt welds of TP347 furnace tube headers
Thread Content
For the butt weld joint of the TP347 furnace tube header with DN300 size and a wall thickness of 50 mm, since the radius of the source is small, is it possible to use UT instead? What are the advantages and disadvantages of this? Are there any other inspection methods available? Of course, in any case, the design unit needs to confirm and approve such changes. Please advise; thank you
Proper stabilization after welding TP347 is essential; otherwise, problems are likely to occur
