Description

A pipe for electronically measuring pipe wall thickness

technical field

The utility model relates to a pipeline, in particular to a pipeline for electronically measuring the thickness of the pipe wall.

Background technique

In the field of construction, pipes can be seen everywhere, especially for municipal pipe networks, which are often buried several meters deep underground. It is troublesome to maintain the municipal pipe network. The water flowing in the pipes for a long time can wear the inside of the pipes, and the pipes The thickness of the wall becomes thinner; when the pipe network becomes thinner to a certain thickness, it needs to be replaced. However, the current municipal pipe network usually uses ordinary pipes, and the thickness of the pipe wall cannot be detected at any time, so that the wear of the pipe cannot be known.

The piezoelectric sensor can output piezoelectric pulse signals, and the piezoelectric pulse signals can be reflected back to the piezoelectric sensor after being transmitted in the medium. The piezoelectric sensor can collect and transmit the output and reflected piezoelectric signals to external equipment, and the external equipment can Analyze the thickness of the medium through the signal.
