[0033] The present invention provides a technical solution in which, during use, a pipe is inserted into a feeding cylinder and then fed into a detection cylinder by a feeding assembly. The pipe is then inspected by a flaw detection assembly. When a damaged area is detected, a water pump inside the water tank is activated, and colored ink from inside the water tank is sprayed onto the damaged area through a nozzle for marking. This facilitates the main staff's query and speeds up the work process.

[0042] Working principle: During use, the pipe is loaded into the feed cylinder and then fed into the inspection cylinder by the feeding assembly. The pipe is then inspected by the flaw detection assembly. When a damaged area is detected, the water pump inside the water tank is activated, spraying colored ink from the tank onto the damaged area through a nozzle.
