The tank structure is typically made of marine-grade steel, with material grades ranging from Q235B to Q345R as per GB/T 3274. The specific grade depends on design temperature and strength requirements.
The design pressure is typically 1.0–1.6 MPa, and the design temperature range is -10 to 60 °C. These values are reference ranges and must be confirmed for the specific application.
Leakage rate is tested at 1.1 times the design pressure, with a maximum allowable leakage of 0.1 mL/min. Additionally, a hydrostatic test at 1.5 MPa is performed for 30 minutes.
Wall thickness ranges from 8 to 25 mm (per GB 150), and corrosion allowance is 1.5 to 3.0 mm (per ISO 12944). These values depend on capacity, pressure, and environmental conditions.
