01Annular joint flaw detector and lead room
Circumferential seam flaw detection and lead room are very important components of LNG cylinder production line.
Their role is to conduct nondestructive test on the tank.
The product can be damaged and protected through the production line composed of high-frequency X-ray flaw detector and lead protection room。
02Annular joint flaw detector and lead room standards
The whole system
Annular joint flaw detector and lead room in line with GB/T 17925-2011 "X-ray digital imaging inspection of butt welds in gas cylinders
