Description

Technical Field

[0001] This utility model relates to the field of industrial testing and quality control technology, specifically a titanium alloy pipe sealing testing device. Background Technology

[0002] Titanium alloy tubes are an important industrial material with wide applications in aerospace, medical, chemical and marine engineering fields. Their unique physical and chemical properties, such as high strength, light weight, corrosion resistance and good biocompatibility, make titanium alloy tubes irreplaceable in these fields.

[0003] Among the existing technologies, the titanium alloy pipe sealing testing device proposed in the authorization announcement number CN222561213U includes: a workbench, a control console fixed on the upper side of the workbench, a testing component fixed on one side of the control console, a sliding component fixed on the upper side of the workbench, a gas transmission component provided on the upper side of the sliding component, and a conveying component in contact with the upper side of the sliding component.

[0004] In existing technologies, the airtightness of both sides of titanium alloy steel pipes is low during inspection, which can easily affect the inspection results. When the leakage hole diameter is small, airtightness detection and infrared detection cannot effectively locate the leakage location, resulting in a high rate of missed detection. Therefore, we propose a titanium alloy pipe sealing detection device. Utility Model Content
