Description

Technical Field

[0002] The oil pipe thickness detection device is a device for measuring the thickness of the oil pipe wall. It is mainly used in the oil and gas industry to ensure the safety and reliability of the oil pipe during use. It can detect corrosion, wear or other problems that may cause changes in the wall thickness of the oil pipe, helping to promptly discover potential safety hazards. A Chinese patent (publication number CN116907408A) discloses an online detection system for the thickness of the inner coating of the oil pipe. The system first detects the coating of the inner circumferential side wall of the oil pipe through a first thickness detection mechanism at one end of the first connecting tube to determine the location of the coating on the inner circumferential side wall of the oil pipe that is unqualified. The second thickness detection mechanism on the second connecting tube detects the coating thickness of the inner circumferential side wall of the oil pipe, thereby detecting the thickness of the specific unqualified location of the coating on the inner circumferential side wall of the oil pipe, and can perform all-round detection of the oil pipe; however, it is not suitable for detecting the inner wall thickness of oil pipes of different specifications. Therefore, the utility model proposes an oil pipe thickness detection device to improve the above-mentioned problem. Utility Model Content
