Thermal melt salt storage tank: issue of 100% RT X-ray inspection for the butt joints of the mid-gusset plates in the entire edge plate
Thread Content
This tank operates at a high temperature of 400 degrees, and the entire tank is to be scanned with X-rays 100%. I’m wondering how to attach the film to the bottom of the tank; my idea is to raise it to a height of 800–1000 units, use TIG welding for the base layer and electric welding for the top layer. Is this approach feasible? I really don’t know how to take photos of those with a diameter of 30 meters. Please share your opinions so we can learn from each other*
Bottom plate? ? ? Are all butt welds of this type?
Yes, it’s a butt joint; the edge plates are arc-shaped, not bow-shaped. No flat strips are used in the butt welds, and all of the mid-section plates of the edge plates are joined by butt joints. X-ray – how should the film be placed?
