Vessel steel plates are made from carbon steel or low-alloy steel, as they offer good strength and toughness at elevated temperatures. These steels are often alloyed with elements such as manganese, silicon, and nickel to enhance their mechanical properties and improve their corrosion resistance.
Our plates offer various grades optimized for high temperature and pressure conditions, ensuring exceptional strength, corrosion resistance, and weldability. Key features include precise dimensional accuracy, excellent surface finish, and superior mechanical properties critical for the reliability and safety of industrial boilers and pressure vessels.
Application of GB Pressure Vessel Plate
Petrochemical industry: Manufacturing equipment such as hydrogenation reactors, catalytic cracking units, high-temperature and high-pressure heat exchangers (design temperature ≤ 550℃), and large storage tanks (requiring resistance to h₂s corrosion environments).
Power industry: Manufacturing equipment such as power station boiler drums (working pressure ≤ 17mpa), superheater/reheater headers, and nuclear power secondary loop pressure vessels.
Other fields: Manufacturing liquefied natural gas (lng) equipment, high-pressure gas cylinders for special vehicles, etc.
Coal chemical industry: Manufacturing equipment such as coal gasifier shells and synthesis tower internals (resistant to syngas corrosion).
Production Process of GB Pressure Vessel Plate
Steelmaking: Electric furnaces or converters are used for steelmaking to remove impurities from molten iron, and alloying elements such as chromium and molybdenum are added at the same time.
Continuous casting: The molten steel that has been smelted is poured into a continuous casting machine, and after cooling and forming, steel billets are obtained.
Rolling: The steel billets are heated and rolled to obtain steel plates with thickness and width meeting the requirements.
Heat treatment: The rolled steel plates are subjected to heat treatment to improve their mechanical properties and corrosion resistance.
Surface treatment: The surface of the steel plates is polished or shot-blasted to improve their surface quality and service life.
