Steel Plate For Low Temperature Pressure Vessel
Steel Plate For Low Temperature 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.
Low-temperature pressure vessel steel is made by enhancing the extremely low-temperature property of existing boiler and pressure vessel quality steel. It is also called high nickel (Ni) steel as it has a high level of nickel content. This product features superb toughness against extremely low temperatures and good resistance to corrosion enabled by the nickel contained. Its common applications include LNG tanks and liquified gas storage tanks. It is also often used in place of expensive stainless steel.
