The device can comprehensively inspect the welds of the pressure vessel, improve the inspection results of the pressure vessel, and effectively reduce the possibility of safety accidents.

[0004] However, the device has a problem that when the pressure vessel to be tested is placed on the rotating drum and rotated, there is no limiting mechanism at the axial ends of the pressure vessel to limit it.

Therefore, a pressure vessel defect detection device is proposed to solve the problem that the existing pressure vessel detection process is prone to offset and affects defect detection.
