Abstract
The present disclosure pertains to a system configured to protect flows in piping systems using minimal spare components. Some embodiments may provide: a first piping subsystem configured to receive a portion of the input flow; a second piping subsystem configured to receive the portion of the input flow by substituting for the first subsystem; a test subsystem configured to detect whether each of the first and second subsystems is able to vent when at least one, in the each subsystem, of a respective pressure and a respective pressure rate satisfies first and second criteria, respectively; and first and second pilots configured to detect a maximum pressure and a maximum pressure rate, respectively, of the portion of the first and second subsystems.
Claims14
A system for responding to pressure changes in a fluid, the system comprising:
- a first piping subsystem that receives an input flow;
- at least one independent second piping subsystem that receives another input flow;
- a third piping subsystem that receives the input flow or the other input flow by respectively substituting for the first piping subsystem or the at least one second piping system;
- a test subsystem that detects whether each of the piping subsystems relieves pressure when at least one of a respective pressure criterion and a respective pressure rate increase criterion is satisfied;
- and
- first and second pilots that detect a maximum pressure and a maximum pressure rate increase, respectively, in each of the piping subsystems,
- wherein the substituting is performed by actuating a set of valves, each valve of which being sized in relation to a diameter of a respective pipe to which the valve is coupled,
- wherein one or more valves associated with the first piping subsystem is of a different size from one or more valves associated with the second piping subsystem, and
- wherein one or more valves associated with the third piping subsystem has a diameter at least as wide as a widest diameter from among the one or more valves associated with each of the first and second piping subsystems.
A method for responding to pressure changes in a fluid by a system, the method comprising:
- providing a first piping subsystems that receives an input flow;
- providing at least one independent second piping subsystem that receives another input flow;
- providing a third piping subsystem that receives the input flow or the other input flow by respectively substituting for the first piping subsystem or the at least one second piping system;
- providing a test subsystem that detects whether each of the piping subsystems relieves pressure when at least one of a respective pressure criterion and a respective pressure rate increase criterion is satisfied;
- and
- providing, in each of the piping subsystems, first and second pilots that detect a maximum pressure and a maximum pressure rate increase, respectively,
- wherein the substituting is performed by actuating a set of valves, each valve of which being sized in relation to a diameter of a respective pipe to which the valve is coupled,
- wherein one or more valves associated with the first piping subsystem is of a different size from one or more valves associated with the second piping subsystem, and
- wherein one or more valves associated with the third piping subsystem has a diameter at least as wide as a widest diameter from among the one or more valves associated with each of the first and second piping subsystems.
