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 a first input flow;
- a second piping subsystem that receives a second input flow, the second piping subsystem being independent of the first piping subsystem;
- a third piping subsystem that receives the first input flow or the second input flow by respectively substituting for the first piping subsystem or second piping system;
- and
- a test subsystem that simulates surge events and detects whether each of the piping subsystems properly vent pressure in response to one or more of the simulated surge events;
- first and second pilots that detect a maximum pressure and a maximum pressure rate increase, respectively, in each of the piping subsystems;
- and
- for each piping subsystem, an associated set of operating valves,
- wherein each operating valve is sized in relation to a diameter of a respective pipe to which the valve is coupled,
- wherein the substituting is performed by actuating the operating valves
- wherein one or more operating valves associated with the first piping subsystem is of a different size from one or more operating valves associated with the second piping subsystem, and
- wherein one or more operating valves associated with the third piping subsystem has a diameter at least as wide as a widest diameter from among the operating 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 third piping subsystem that receives the first input flow or the second input flow by respectively substituting for the first piping subsystem or the second piping system;
- providing a test subsystem that simulates surge events and detects whether each of the piping subsystems properly vent pressure in response to one or more of the simulated surge events event;
- providing, in each of the piping subsystems, first and second pilots that detect a maximum pressure and a maximum pressure rate increase, respectively;
- and
- providing, for each piping subsystem, an associated set of operating valves,
- wherein each operating valve is sized in relation to a diameter of a respective pipe to which the valve is coupled,
- wherein the substituting is performed by actuating the operating valves,
- wherein one or more operating valves associated with the first piping subsystem is of a different size from one or more operating valves associated with the second piping subsystem, and
- wherein one or more operating 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.
