Thick-Gauge Pressure Vessel Tank Plate

As the core material of pressure-bearing equipment, the performance of thick-gauge pressure vessel tank plates directly affects the safe production in fields such as energy, chemical industry, and nuclear power. These special steel plates typically use high-quality steel such as Q345R and SA516Gr70, and employ controlled rolling and controlled cooling processes to ensure mechanical properties within a thickness range of 20-150mm. They possess high strength (tensile strength ≥510MPa), good low-temperature toughness (impact energy at -40℃ ≥34J), and excellent welding characteristics.

In modern manufacturing, micro-alloying design (adding elements such as Nb, V, and Ti) and intelligent rolling technology are used to achieve weight reduction optimization while ensuring the pressure-bearing capacity of the tank plates. Before leaving the factory, they must undergo 100% ultrasonic testing, hardness testing, and other 7 quality inspection processes to ensure that the yield strength fluctuation value of each steel plate does not exceed 30MPa, providing reliable protection for key equipment such as large LNG storage tanks and hydroreactors.
