Nondestructive testing device for welding seam of pressure vessel

Abstract

The invention discloses a nondestructive testing device for a welding seam of a pressure vessel, and belongs to the technical field of pressure vessel detection. The nondestructive testing device comprises the pressure vessel, a supporting plate, a clamping device, an external fixing device, a detecting device and a clamping device. The supporting plate is arranged on the outer wall of the pressure vessel, the clamping device is installed at the top of the supporting plate, an external fixing device is installed at the bottom of the supporting plate, a detection device is arranged on the external fixing device, and a clamping device is installed on the outer wall of the detection device. According to the invention, the detection device can be stably made to do circular motion through the arranged external fixing device, and then 360-degree damage-free detection on the outer surface of a pressure vessel is achieved.

Description

technical field [0001] The invention relates to the technical field of pressure vessel detection, in particular to a non-destructive detection device for pressure vessel welds. Background technique [0002] Non-destructive testing is to use the characteristics of sound, light, magnetism and electricity to detect whether there is a defect or inhomogeneity in the object to be inspected without damaging or affecting the performance of the object to be inspected, and to give the size, position, and location of the defect. The general term for all technical means to determine the technical state of the inspected object (such as whether it is qualified or not, the remaining life, etc.), and the information such as the nature and quantity, and the patent application number CN201822059595. The X-ray DR imaging detection system for straight welds includes a gantry positioner, a detection conveying line arranged under the gantry positioner for transporting pressure vessels, and a conv...

Problems solved by technology

The advantage of this device is that it improves the imaging quality, improves the detection efficiency, and reduces the labor force; the disadvantage is that it realizes the double-wall single-image digital dynamic and static on-line automatic passing of the ring straight weld quality of the pressure steel cylinder with a diameter of 0.5-1.2m. Dynamic and static imaging detection cannot realize automatic detection of various pressure vessels. Therefore, the above problems need to be solved
