The refining industry involves complex process systems that convert crude oil into high-value fuels and petrochemical feedstocks through critical operations such as distillation, catalytic cracking, hydroprocessing, reforming, coking, gas separation, and sulfur recovery. These operations typically occur under extreme conditions—high temperatures, high pressures, corrosive and flammable environments—placing stringent demands on equipment reliability.

As essential components of refinery infrastructure, pressure vessels are engineered to withstand such harsh conditions. Their versatility in structure, high pressure resistance, and sealing capability make them indispensable for key applications including chemical reactions, phase separation, storage, heat exchange, and system buffering—ensuring safe, stable, and continuous refinery operations.
