System and method for heating and re-rounding spoolable pipe

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.

         21 . A system, comprising:
 a spoolable pipe deployment device configured to deploy coils or reels of spoolable pipe;   a pipe heater configured to receive the spoolable pipe from the spoolable pipe deployment device and to heat the spoolable pipe to provide a heated spoolable pipe; and   a pipe re-rounder configured to receive the heated spoolable pipe from the pipe heater and to re-round the heated spoolable pipe to provide a rounded spoolable pipe.   
     
     
         22 . The system of  claim 21 , 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. 
     
     
         23 . The system of  claim 21 , 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.   
     
     
         24 . The system of  claim 21 , wherein the pipe heater comprises:
 connectors configured to electrically connect to a conductive layer of the spoolable pipe; and   a power source configured to provide electrical power to the conductive layer via the connectors thereby heating the spoolable pipe.   
     
     
         25 . The system of  claim 21 , comprising a hot air blower configured to blow hot air through an interior of the spoolable pipe. 
     
     
         26 . The system of  claim 21 , 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. 
     
     
         27 . The system of  claim 26 , 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.   
     
     
         28 . The system of  claim 21 , comprising a deployment trailer, wherein the deployment trailer comprises:
 a trailer bed;   the 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.   
     
     
         29 . The system of  claim 21 , comprising:
 a deployment trailer comprising:
 a deployment trailer bed; and 
 the 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.   
     
     
         30 . A method, comprising:
 providing a pipe heating and re-rounding system comprising:
 a spoolable pipe deployment device; 
 a pipe heater; and 
 a pipe re-rounder; 
   deploying coils or reels of spoolable pipe via the spoolable pipe deployment device;   receiving the spoolable pipe from the spoolable pipe deployment device at the pipe heater;   heating the spoolable pipe using the pipe heater to provide a heated spoolable pipe;   receiving the heated spoolable pipe from the pipe heater at the pipe re-rounder; and   re-rounding the heated spoolable pipe using the pipe re-rounder to provide a rounded spoolable pipe.   
     
     
         31 . The method of  claim 30 , comprising heating the spoolable pipe using the pipe heater via at least one of inductive heating, resistive heating, conductive heating, convective heating, or radiative heating. 
     
     
         32 . The method of  claim 30 , comprising maintaining a temperature of the heated spoolable pipe via blowing hot air through an interior of the spoolable pipe via a hot air blower. 
     
     
         33 . The method of  claim 30 , wherein re-rounding the heated spoolable pipe comprises engaging an outer surface of the heated spoolable pipe via a pair of rollers. 
     
     
         34 . The method of  claim 30 , comprising heating a coil or reel of the spoolable pipe using a coil heater or reel heater prior to heating the spoolable pipe using the pipe heater. 
     
     
         35 . The method of  claim 30 , comprising conveying the spoolable pipe through the pipe heater and the pipe re-rounder using a deployment actuator. 
     
     
         36 . The method of  claim 30 , comprising:
 engaging heated spoolable pipe having a first outer diameter using a first pair of rollers; and   engaging heated spoolable pipe having a second outer diameter using a second pair of rollers.
