In recent years, the trend of large-scale and high-parameterization of pressure vessel products has become increasingly obvious. Therefore, the research and development of materials for high temperature, high pressure and corrosion resistant pressure vessels has been a major issue facing the pressure vessel industry.
At present, the main research results and technological progress of materials for pressure vessels are: The high purity of the material: the improvement of the overall technical level and equipment level of the metallurgical industry, greatly improving the purity of the material, mechanical properties of the material for the pressure vessel, and overall safety of the pressure vessel.
Media suitability of materials: For various corrosive media and operating conditions, metal materials such as super stainless steel, duplex steel and special alloy have been researched and developed to suit various application conditions.
Application limits of materials: research on high temperature creep, temper embrittlement, low temperature brittle fracture, accurately give the application range of materials.
Application of higher strength materials: Under the requirements of large-scale equipment, traditional materials cannot solve the selection of materials such as 30,000 cubic meters of natural gas spherical tanks, large spherical tanks of steel mills, 200,000 cubic meters of crude oil storage tanks and ultra-high pressure vessels problem. At present, the application of high-strength materials with σb≥800MPa is attracting wide attention of domestic researchers.
