High temperature boiler steel plate
High-temperature boiler steel plates are widely used in petroleum, chemical, power station, boilers and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, and liquefaction Equipment and components such as oil and gas cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.
