In our physics laboratory, there is one tensile testing machine, one hardness tester, two coating thickness gauges, and one surface roughness tester that is imported from Japan. These devices could detect tube’s hardness, tensile strength, yield strength, surface roughness, elongation rate, zinc layer thickness and other parameters. These data reveal tube quality directly, thus offering powerful data support for research projects.
