JIS G 3115 SPV 235 is a low-carbon steel plate for pressure vessels, compliant with Japanese Industrial Standards (JIS), primarily used for manufacturing pressure vessels operating at room temperature or medium-to-low temperature environments.
Pressure Vessel Manufacturing: SPV 235 is suitable for producing boilers, gas storage tanks, and liquefied petroleum gas (LPG) tanks for normal or medium-to-low temperature conditions, widely used in industries such as petroleum, chemical, and power plants.
Industrial Storage Tanks: Used for storing liquids or gases, such as chemical storage tanks, oil tanks, or natural gas tanks, due to its excellent weldability and toughness.
Piping Systems: Employed in manufacturing pipelines or pipeline components that withstand certain pressures, particularly in the chemical and energy industries.
Energy Equipment: Used in thermal or nuclear power plants for manufacturing boiler components, heat exchangers, or other pressure-bearing equipment.
Marine and Offshore Engineering: Certain marine engineering equipment or ship pressure vessel components may use SPV 235 due to its reliable strength and toughness at medium-to-low temperatures.
