Abstract

A system includes a pipe heater configured to heat spoolable pipe to provide a heated spoolable pipe and a pipe re-rounder configured to re-round the heated spoolable pipe to provide a rounded spoolable pipe. The system may also include a controller configured to control the pipe heater and the pipe re-rounder.

First claim

What is claimed is:

1. A system, comprising:
a pipe heater configured to heat spoolable pipe to provide a heated spoolable pipe;
a pipe re-rounder configured to re-round the heated spoolable pipe to provide a rounded spoolable pipe; and
a deployment trailer, wherein the deployment trailer comprises:
a trailer bed;
a spoolable pipe deployment device coupled to the trailer bed;
the pipe heater coupled to the trailer bed; and
the pipe re-rounder coupled to the trailer bed.

2. The system of claim 1 , wherein the pipe heater comprises an induction coil configured to heat the spoolable pipe as the spoolable pipe passes through an interior of the induction coil.

3. The system of claim 1 , wherein the pipe heater comprises:
an enclosure configured to enclose at least a portion of the spoolable pipe;
a fluid contained within the enclosure; and
a heating element disposed within the enclosure, wherein the heating element is configured to heat the fluid thereby heating the portion of the spoolable pipe within the enclosure.

4. The system of claim 1 , further comprising a hot air blower configured to blow hot air through an interior of the spoolable pipe.

5. The system of claim 1 , wherein the pipe re-rounder comprises a pair of rollers configured to engage with an outer surface of the heated spoolable pipe to provide the rounded spoolable pipe.

6. The system of claim 1 , wherein the pipe re-rounder comprises:
a first pair of rollers configured to engage with heated spoolable pipe having a first outer diameter; and
a second pair of rollers configured to engage with heated spoolable pipe having a second outer diameter.

7. The system of claim 1 , further comprising:
a controller configured to control the pipe heater and the pipe re-rounder, wherein the controller comprises a processor configured to:
heat the spoolable pipe using the pipe heater; and
re-round the heated spoolable pipe using the pipe re-rounder.

8. The system of claim 7 , comprising a temperature sensor configured to provide a signal indicative of a temperature of the heated spoolable pipe to the controller.

9. The system of claim 7 , comprising:
a deployment actuator configured to adjust a deployment speed of the rounded spoolable pipe based on a desired speed signal from the controller; and
a deployment speed sensor configured to provide a signal indicative of the deployment speed to the controller.

10. The system of claim 7 , comprising:
a re-rounder actuator configured to adjust a re-rounding force applied to the heated spoolable pipe based on a desired re-rounding force signal from the controller; and
a re-rounding force sensor configured to provide a signal indicative of the re-rounding force to the controller.

11. The system of claim 7 , wherein the pipe heater comprises an induction coil configured to heat the spoolable pipe as the spoolable pipe passes through an interior of the induction coil.

12. A system, comprising:
a pipe heater configured to heat spoolable pipe to provide a heated spoolable pipe;
a pipe re-rounder configured to re-round the heated spoolable pipe to provide a rounded spoolable pipe; and
a deployment trailer comprising:
a deployment trailer bed;
a spoolable pipe deployment device coupled to the trailer bed; and
a pipe heating and re-rounding trailer comprising a heating and re-rounding trailer bed, wherein the pipe heater and the pipe re-rounder are coupled to the heating and re-rounding trailer bed, and the heating and re-rounding trailer bed is coupled to the deployment trailer.

13. The system of claim 12 , wherein the pipe heater comprises:
an enclosure configured to enclose at least a portion of the spoolable pipe;
a fluid contained within the enclosure; and
a heating element disposed within the enclosure, wherein the heating element is configured to heat the fluid thereby heating the portion of the spoolable pipe within the enclosure.

14. The system of claim 12 , further comprising a hot air blower configured to blow hot air through an interior of the spoolable pipe.

15. The system of claim 12 , wherein the pipe re-rounder comprises a pair of rollers configured to engage with an outer surface of the heated spoolable pipe to provide the rounded spoolable pipe.

16. The system of claim 12 , wherein the pipe re-rounder comprises:
a first pair of rollers configured to engage with heated spoolable pipe having a first outer diameter; and
a second pair of rollers configured to engage with heated spoolable pipe having a second outer diameter.

17. The system of claim 12 , further comprising:
a controller configured to control the pipe heater and the pipe re-rounder, wherein the controller comprises a processor configured to:
heat the spoolable pipe using the pipe heater; and
re-round the heated spoolable pipe using the pipe re-rounder.

18. The system of claim 17 , comprising a temperature sensor configured to provide a signal indicative of a temperature of the heated spoolable pipe to the controller.

19. The system of claim 17 , comprising:
a deployment actuator configured to adjust a deployment speed of the rounded spoolable pipe based on a desired speed signal from the controller; and
a deployment speed sensor configured to provide a signal indicative of the deployment speed to the controller.

20. The system of claim 17 , comprising:
a re-rounder actuator configured to adjust a re-rounding force applied to the heated spoolable pipe based on a desired re-rounding force signal from the controller; and
a re-rounding force sensor configured to provide a signal indicative of the re-rounding force to the controller.
