Technical Field
[0001] This application relates to the technical field of galvanized pipe detection, and particularly to a device for detecting the galvanized thickness of galvanized pipes. Background Art
[0002] Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend its service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oilfields. When leaving the factory, a device for detecting the galvanized thickness is required.
[0003] Traditional methods for detecting the thickness of galvanized layers usually include two types: destructive testing and non-destructive testing. Although destructive testing is accurate, it will damage the product and is not suitable for real-time detection on the production line. Although non-destructive testing will not damage the product, it often has low accuracy and complex operations, and cannot meet the requirements for rapid, accurate, and non-destructive detection of the galvanized layer thickness on the galvanized pipe production line. For this reason, this application proposes a device for detecting the galvanized thickness of galvanized pipes to solve the above problems. Utility Model Content

[0010] As a preferred embodiment, the number of the measuring probes is six, and the six measuring probes are parallelly distributed at the bottom of the fixed strip. A transmitter and a receiver are arranged in the inner cavity of the measuring probe.
[0011] By adopting the above technical solution, different positions of the galvanized pipe can be detected simultaneously, and the average value is taken as the final result, improving the accuracy of the detection.
[0012] As a preferred embodiment, a data processing unit is arranged in the inner cavity of the control box, and the data unit is electrically connected between the transmitter and the receiver. The display screen is electrically connected to the data processing unit. The control box, the data processing unit and the warning lamp are electrically connected.
