The Haifeng Haimei Industrial Gas Factory Cylinder Periodic Inspection and Evaluation Dataset covers the following items: manufacturer name, gas cylinder use registration certificate number, cylinder serial number, factory serial number, manufacturing date, filling medium, cylinder specification, approval certificate number, nominal working pressure, hydrostatic test pressure, actual volume, actual weight, design wall thickness, last inspection date, visual inspection, acoustic inspection, bottle mouth thread inspection, weight and volume measurement, test water temperature, total deformation value, residual deformation value, residual deformation rate, test conclusion, etc. The outer-side hydrostatic test is conducted on seamless steel gas cylinders using a dedicated hydrostatic test device. An advanced data collector connected with flow sensors and weight sensors for the automatic control module is employed to collect data including pressure, temperature and leakage volume. High-precision electronic balances are adopted to obtain the total and residual volume deformation values of the test cylinders, and the volume residual deformation rate is calculated as the ratio of the residual volume deformation value to the total volume deformation value. This dataset can be applied in the periodic inspection field of seamless steel gas cylinders: it is used to determine the volume residual deformation rate of in-service high-pressure gas cylinders (with a test pressure of 22.5 MPa), verify the safe load-bearing capacity of the cylinders, and ensure their safety and reliability. It can also be used for research on gas cylinder safety inspection and detection technologies, providing data support for the optimization of inspection methods and improving inspection efficiency.
