Problems solved by technology
[0003] However, the height of the acoustic emission flaw detector on the existing pressure vessel defect detection device is inconvenient to adjust, which makes the distance between the acoustic emission flaw detector and the weld seam inconsistent, the detection error is large, and the accuracy of the detection result is reduced. Therefore, we propose a pressure vessel Defect detection device and detection method thereof are used to solve the above problems

The invention discloses a pressure vessel defect detection device and a detection method thereof, wherein the pressure vessel defect detection device includes a base, the top of the base is welded with a first bottom plate, and the top of the first bottom plate is movably mounted with a second bottom plate, The top side of the second bottom plate is welded with a slip ring, and the outer sliding sleeve of the slip ring is provided with a mounting plate, and an acoustic emission flaw detector is fixedly installed on one side of the mounting plate. The four corners of the top of the bottom plate are provided with a plurality of second chute, and the same sleeve is slidably installed in the first chute and the second chute on the same vertical axis, and the two ends of the sleeve are connected with the first chute respectively. The groove communicates with the second chute. The invention is reasonable in design, easy to operate, convenient to adjust and raise the height of the slip ring, so that the position of the slip ring can be consistent with the height of the storage tank to be tested, and the acoustic emission flaw detector can be closely attached to the weld seam on the storage tank to be tested, improving Detection effect.
Description
technical field [0001] The invention relates to the technical field of defect detection tools, in particular to a pressure vessel defect detection device and a detection method thereof. Background technique [0002] Pressure vessels play an extremely important role in the petrochemical industry. As a type of pressure vessel, horizontal storage tanks are often used to store oil, natural gas and their extracts. Because most of the horizontal storage tanks store flammable, explosive, corrosive or toxic substances, the integrity of the storage tanks must be ensured , Regular inspection of storage tanks. Due to the large volume of horizontal storage tanks, the tank body is mostly welded by multi-section cylinders, and there are annular welds on the tank body. Due to reasons such as welding process, improper welding operation, and stress concentration, etc. Seam. After retrieval, the patent document with the application number 201720851191.1 discloses a pressure vessel defect d...
