SAMR: Deepen Special Rectification on Risks and Hidden Dangers of Saturated Water Steam Spherical Tanks

36Kr reports that the State Administration for Market Regulation has issued a notice on deepening special rectification on risks and hidden dangers of saturated water steam spherical tanks. The notice stipulates that design units for newly manufactured spherical tanks must effectively conduct risk assessments during the design phase based on the design conditions proposed by the client. Risk assessments should consider damage modes such as alkaline stress corrosion and corrosion fatigue, evaluate and calculate potential hazards from saturated water flashing and explosions, analyze risks of instrument line freezing in low-temperature environments, and propose preventive measures including hardness testing of welded joints after post-weld heat treatment, regular water quality testing inside the tank, automatic control of water levels, and optimization of insulation layer structure design.
