What is use of pressure relief line?

A pressure relief line is used to safely divert excess pressure from a system, preventing potential overpressure situations that could lead to equipment failure or hazardous conditions. It typically directs the excess pressure to a safe location or a containment system. By ensuring that the pressure remains within safe operating limits, it protects both personnel and equipment from potential damage. This is crucial in industries such as oil and gas, chemical processing, and water treatment.
