Key points of manufacturing control for waste heat boilers
Thread Content
Key points in the manufacturing control of waste heat boilers HRSG. This is my first exposure to this area; could experts please explain it? Additionally, in the ASME S case, 1. Is weld procedure qualification required for fin high-frequency welding HFRW? 2. For the fillet welds in the welding of headers and tube bundles, how can full penetration be verified? Should RT or UT be used?
For the welding of high-frequency welded finned tubes, a welding process evaluation must be carried out; refer to JB/T6512 for specific details
1- Welding procedure qualification is required. 2- For fillet welds, PT or MT is sufficient.
