Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel pipe detection, in particular to a galvanized steel pipe rapid detection device. Background Art

[0002] Galvanized steel strip pipe refers to a kind of pipe with a zinc layer on the surface after pre-treatment of the strip steel. It is also called galvanized steel strip pipe. Galvanized steel strip pipe is widely used in construction, chemical industry, manufacturing industry, sports equipment, petroleum and petrochemical, environmental protection and other fields. It has the characteristics of corrosion resistance, wear resistance and high strength.

[0003] Currently, finished galvanized steel pipes need to be tested for hardness before they are put into use. The traditional method is to press the sample with a pressure head and calculate the hardness based on the damage or deformation on the surface of the steel pipe. However, when testing round galvanized steel pipes, they cannot be quickly fixed and are difficult to test quickly. Therefore, we propose a rapid testing device for galvanized steel pipes.
