What are the differences between Class 1 and Class 2 pressure vessels in terms of equipment cost and management?

The first category of pressure vessels typically refers to those with high operating pressures, high operating temperatures, or hazardous media; they have strict safety requirements as well as high standards for design, manufacturing, and inspection, which results in relatively high costs for such equipment. The second category of pressure vessels are those that operate under milder conditions; accordingly, their safety requirements are lower, so their cost is generally lower than that of the first category. In terms of management, stricter requirements apply to the first category of pressure vessels. This includes, but is not limited to, aspects such as design review, material selection, welding, non-destructive testing, installation, commissioning, regular inspections, as well as maintenance and monitoring during operation. As for the second category of pressure vessels, although they also have a comprehensive set of strict management procedures, compared to those in the first category, certain management requirements are relatively less stringent due to the relatively lower level of danger in their operating environments. .
