Tubing straightener

Abstract

A tubing straightener includes a housing having a tubing receiving end and a tubing ejection end. At least one set of drive rollers is positioned within the housing and disposed between the first end and the second end. The drive rollers engage tubing to be straightened such that, in use, the drive rollers apply a driving force to the tubing. Each drive roller has more than one circumferential profile for engaging tubing of different diameters. At least one top guide roller and at least one bottom guide roller for guiding the tubing through the housing.

1 . A tubing straightener, comprising:
 a housing having a tubing receiving end and a tubing ejection end;   at least one set of drive rollers positioned within the housing and disposed between the first end and the second end, the drive rollers engaging tubing to be straightened such that, in use, the drive rollers apply a driving force to the tubing, each drive roller having more than one circumferential profile for engaging tubing of different diameters; and   at least one top guide roller and at least one bottom guide roller for guiding the tubing through the housing, the drive rollers and the guide rollers straightening the tubing as it passes through the housing.   
   
   
       2 . The tubing straightener of  claim 1 , wherein the position of at least one guide roller is adjustable such that a desired bend is applied to the tubing. 
   
   
       3 . The tubing straightener of  claim 1 , further comprising a first connection for removably connecting a first power source to the set of drive rollers, and a second connection for removably connecting a second power source to the set of drive rollers. 
   
   
       4 . The tubing straightener of  claim 3 , wherein the first connection has a higher gear ratio than the second connection. 
   
   
       5 . The tubing straightener of  claim 3 , wherein the second connection is connected to the set of rollers closest to the tubing ejection end of the housing. 
   
   
       6 . The tubing straightener of  claim 3 , further comprising a third connection for removably connecting one of the first power source and the second power source to a set of drive rollers closest to the tubing ejection end of the housing. 
   
   
       7 . The tubing straightener of  claim 3 , wherein the first power source is a manual crank, and the second power source is a motor. 
   
   
       8 . A tubing straightener, comprising:
 a housing having a tubing receiving end and a tubing ejection end;   at least one set of drive rollers positioned within the housing and disposed between the first end and the second end, the drive rollers engaging tubing to be straightened such that, in use, the drive rollers apply a driving force to the tubing;   at least one top guide roller and at least one bottom guide roller for guiding the tubing through the housing, the drive rollers and the guide rollers straightening the tubing as it passes through the housing;   a first connection for removably connecting a first power source to the set of drive rollers; and   a second connection for removably connecting a second power source to the set of drive rollers.   
   
   
       9 . The coil tubing straightener of  claim 8 , wherein each roller in a set of rollers rotates on a common plane of rotation. 
   
   
       10 . The coil tubing straightener of  claim 9 , wherein each roller has more than one circumferential profile of differing sizes, such that the rollers define more than one tubing-receiving apertures of differing sizes. 
   
   
       11 . The tubing straightener of  claim 8 , wherein the position of at least one guide roller is adjustable such that a desired bend is applied to the tubing. 
   
   
       12 . The tubing straightener of  claim 8 , wherein the first connection has a higher gear ratio than the second connection. 
   
   
       13 . The tubing straightener of  claim 8 , wherein the second connection is connected to the set of rollers closest to the tubing ejection end of the housing. 
   
   
       14 . The tubing straightener of  claim 8 , further comprising a third connection for removably connecting one of the first power source and the second power source to a set of drive rollers closest to the tubing ejection end of the housing. 
   
   
       15 . The tubing straightener of  claim 8 , wherein the first power source is a manual crank, and the second power source is a motor.
