Which components are typically found inside a pressure vessel?

Baffles, tubes, and supports are essential components found inside pressure vessels, as they play critical roles in the vessel's overall function and safety. Baffles are used to direct fluid flow and enhance the mixing process or improve heat exchange efficiency, thereby increasing the effectiveness of the pressure vessel's purpose, such as in reactors or heat exchangers. Tubes are often part of heat exchanger designs, facilitating the transfer of heat between two fluids by maximizing the surface area for heat exchange. Supports are crucial for maintaining the structural integrity of the pressure vessel under operating conditions, ensuring that the internal components are secure and correctly positioned, which is vital for safe and efficient operation.

The other options represent components that may be associated with systems related to pressure vessels but are not typically found inside them. For instance, pipes, valves, and fittings are external to the pressure vessels and are used to connect the vessel to other parts of a system. Filters, gauges, and sensors are often utilized in conjunction with pressure vessels to monitor and control various parameters, but these are usually installed externally. Insulation and protective coatings are applied to the exterior of the pressure vessel to manage temperature and protect against environmental factors, rather than being contained within the vessel itself.
