Description

Technical Field

[0001] The utility model relates to the field of surface water removal devices, in particular to a pipe surface coupled water removal device suitable for water immersion ultrasonic flaw detection. Background Art

[0002] Water immersion ultrasonic testing is a non-destructive testing method that uses water as a coupling medium to obtain information about the internal structure and defects of the object by completely or partially immersing the object under test in water. In existing technologies, water immersion ultrasonic testing uses water as a coupling medium. When the steel pipe passes through the testing equipment, coupled water will remain on the surface of the steel pipe. If it is not removed in time, it will cause rust on the steel pipe surface. Therefore, designing a device that can easily remove the coupled water on the surface of the steel pipe after testing has better application prospects. Utility Model Content

[0003] The purpose of the utility model is to provide a device for removing coupled water on the surface of pipe fittings suitable for water immersion ultrasonic testing, so as to solve the problem in the prior art proposed in the above background technology that, because water immersion ultrasonic testing uses water as a coupling medium, coupled water will remain on the surface of the steel pipe when the steel pipe passes through the testing equipment.
