Pipe with integrated process monitoring
View Patent ↗The present invention provides a pipe featuring an inner core; an outer pipe wall; and measurement instrumentation configured or arranged between the inner core and outer pipe wall, and also configured to respond to one or more process variables related to media flowing in the pipe and to provide a signal containing information about the one or more process variables. The pipe may include a pipe liner configured inside the outer pipe wall, where the measurement instrumentation in configured on the inside of the pipe liner.
1. A pipe comprising:
an outer pipe wall;
an inner core or pipe liner configured inside the outer pipe wall, and also configured to be resistant to abrasion caused by media flowing in the pipe; and
measurement instrumentation configured or arranged between the inner core or pipe liner and the outer pipe wall, configured to respond to an input voltage signal and provide a measurement instrumentation pulse, and also configured to respond to a reflected measurement instrumentation pulse containing information about one or more process variables related to media flowing in the pipe and to provide a reflected measurement instrumentation pulse signal containing information about the one or more process variables,
wherein the measurement instrumentation comprises a piezo-polymer sensor that is arranged between the inner core or pipe liner and an intermediate liner or layer.
2. A pipe according to claim 1 , wherein the piezo-polymer sensor is situated on a wall of the inner core or pipe liner.
3. A pipe according to claim 1 , wherein the piezo-polymer sensor is configured to respond to the input voltage signal and provide a piezo polymer pulse, and also to respond to a reflected piezo polymer pulse and provide a reflected piezo polymer pulse signal containing information about the one or more process variables.
4. A pipe according to claim 2 , wherein the piezo-polymer sensor includes polymers that are thin and can be placed directly on the wall of the inner core or pipe liner without substantially impacting the shape or form of the pipe.
5. A pipe according to claim 1 , wherein the intermediate liner or layer is made of rubber.
6. A pipe according to claim 1 , wherein the measurement instrumentation is configured to measure flow rate, pipe wall thickness, or some combination thereof.
7. A pipe according to claim 1 , wherein the one or more process variables include mechanical diagnostics for pump and valve actuation.
8. A pipe according to claim 1 , wherein the pipe wall is made of metal.
9. A pipe according to claim 1 , wherein the inner core or pipe liner is configured to cover an inner surface of the pipe wall.
10. A pipe according to claim 1 , wherein the one or more process variables related to media flowing in the pipe include one or more structural characteristics of the pipe itself caused by the media flowing in the pipe, including pipe wall thickness.
11. A pipe according to claim 1 , wherein the one or more process variables related to media flowing in the pipe include flow rate of the media.
12. A pipe according to claim 1 , wherein the measurement instrumentation is configured so as to be equally spaced circumferentially arranged on the inside of the inner core or pipe liner.
13. A pipe comprising:
an outer pipe wall;
an inner core or pipe liner configured inside the outer pipe wall, and also configured to be resistant to abrasion caused by media flowing in the pipe;
a rubber liner or layer configured between the outer pipe wall and the inner core or pipe liner; and
piezo-polymer sensors configured or arranged between the inner core or pipe liner and the rubber liner or layer, configured to respond to an input voltage signal and provide piezo-polymer sensor pulses, and also configured to respond to reflected piezo-polymer sensor pulses containing information about one or more process variables related to media flowing in the pipe and to provide reflected piezo-polymer sensor pulse signals containing information about the one or more process variables.
14. A pipe according to claim 13 , wherein the piezo-polymer sensors are configured on the inside of the inner core or pipe liner or forms an integral part of the inner core or pipe liner.
15. A pipe liner according to claim 13 , wherein the piezo-polymer sensors are configured to measure flow rate, pipe wall thickness, or some combination thereof.
16. A pipe according to claim 13 , wherein the piezo-polymer sensors are configured so as to be equally spaced circumferentially arranged on the inside of the inner core or pipe liner.
17. A pipe according to claim 13 , wherein the piezo-polymer sensors are situated on a wall of the inner core or pipe liner.
