Can X-ray be used for non-destructive testing of butt welds of pipes with a wall thickness less than 2mm?
It should be possible. I haven't heard that there is a limit to the minimum thickness for radiographic inspection.
I think it can. "Safety Technical Regulations for Steam Boilers" and "Safety Technical Regulations for Hot Water Boilers" both provide ranges for the thickness of radiographic testing. ； Article 86 of the "Pressure Vessel Safety Technical Supervision Regulations" stipulates that the upper limit of thickness for radiographic testing is 38mm. Therefore, 2mm butt welds can be subjected to radiographic inspection.
Yes, according to JB/T4730-2005 "Nondestructive Testing of Pressure Equipment", the minimum wall thickness for radiographic testing is 2mm. I have asked professionals and it is actually feasible.
Butt welds of pipes with a wall thickness less than 2 mm can be non-destructively tested using X-rays, but they cannot be graded because there is no standard to implement them.
Yes, I haven’t found any standards that have thickness requirements for X-ray non-destructive testing.
It's possible, but the effect isn't very obvious.
According to "JB/T4730.2-2005" section 6.1.1, the wall thickness should be greater than or equal to 2mm
