Steel Plate For Boiler & Pressure Vessel
Steel Plate For Boiler & Pressure Vessel
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures. Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant. There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methyl isocyanate. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.
This steel is extensively used for vessels designed to store energy sources such as crude oil, natural gas and LNG. These vessels must provide the environment required for the energy source contained including high pressure and extremely low or high temperature. Therefore, the steel used for this purpose requires excellent workability, weldability, heat resistance and corrosion resistance. POSCO’s boiler & pressure vessel quality steel is widely used for applications that handle various energy sources, including gas ball tank, LPG tanks, crude oil or other liquified material tanks, storage tanks and thermal power boilers.
