How is RT non-destructive testing performed on valves?
Thread Content
I have a valve that needs to undergo non-destructive testing (RT). The valve is a diaphragm valve with a diameter of DN50. How many photos are needed? Can it be done for the entire valve body? Is RT non-destructive testing performed on individual points or on the entire area?
RT testing refers to radiographic testing; it is sufficient to examine the main areas, as taking X-rays of the entire area is very costly.
Oh! I see. Generally, how large can the area of a single frame be? For the valves to be exported, do you know to what extent they need to be tested?
The inspection and evaluation criteria can refer to MSS SP-54. We also handle export orders, and we are capable of inspecting parts of any size; valve diameters of any magnitude can be inspected.
Thank you so much. I’ve learned it already; I downloaded this standard from the internet and am currently studying it
