What can be installed if the vent location is inaccessible at high points in a piping system?

When addressing the issue of venting at high points in a piping system, bleed lines to an accessible location provide an effective solution. Inaccessible vent locations can lead to air entrapment within the system, which can disrupt the flow of fluids and lead to inefficiencies or even damage. By installing bleed lines, operators can effectively remove trapped air by rerouting it to a more accessible area for proper venting. This not only ensures that the system functions optimally but also allows for maintenance and purging of air without the need for complicated or intrusive measures.

The other options do not resolve the issue of inaccessible venting effectively. While pressure relief valves are important for safety in systems under pressure, they do not address the venting of air at high points. Manual valves can control flow but do not provide a means for venting trapped air in the system. Additional air separators may improve air separation but don’t directly solve the problem of venting air from high points that are not easily accessible. Thus, the installation of bleed lines stands out as the most practical solution for managing air within an inaccessible high point in a piping system.
