In addition, the system includes a tubing straightener trailer pivotally coupled to the tubing support trailer. The tubing straightening trailer includes a cart having a longitudinal cart axis and including a plurality of wheels. In addition, the tubing straightener trailer includes a tubing straightening assembly coupled to the cart. The tubing straightening assembly is configured to move laterally relative to the cart and the cart axis. The tubing straightening assembly includes a plurality of rollers configured to engage and reduce the curvature of the tubing paid out from the spool.
Other embodiments disclosed herein are directed to a tubing straightener trailer for straightening tubing paid out from a spool. In an embodiment, the tubing straightener trailer includes a cart having a longitudinal cart axis and including a plurality of wheels. In addition, tubing straightener trailer includes a tubing straightening assembly coupled to the cart. The tubing straightening assembly is configured to move laterally relative to the cart and the cart axis. The tubing straightening assembly includes a plurality of rollers configured to engage and reduce the curvature of the tubing paid out from the spool.
Still other embodiments disclosed herein are directed to a method for deploying tubing disposed on a spool. In an embodiment, the method includes (a) feeding the tubing through a tubing straightening assembly, wherein the tubing straightening assembly is moveably coupled to a cart having a longitudinal cart axis. In addition, the method includes (b) engaging the tubing with a plurality of rollers mounted within the tubing straightening assembly during (a).

Embodiments described herein comprise a combination of features and characteristics intended to address various shortcomings associated with certain prior devices, systems, and methods. The foregoing has outlined rather broadly the features and technical characteristics of the disclosed embodiments in order that the detailed description that follows may be better understood. The various characteristics and features described above, as well as others, will be readily apparent to those skilled in the art upon reading the following detailed description, and by referring to the accompanying drawings. It should be appreciated that the conception and the specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes as the disclosed embodiments. It should also be realized that such equivalent constructions do not depart from the spirit and scope of the principles disclosed herein.
For a detailed description of exemplary embodiments, reference will now be made to the accompanying drawings in which:
The following discussion is directed to various exemplary embodiments. However, one skilled in the art will understand that the examples disclosed herein have broad application, and that the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to suggest that the scope of the disclosure, including the claims, is limited to that embodiment.
Certain terms are used throughout the following description and claims to refer to particular features or components. As one skilled in the art will appreciate, different persons may refer to the same feature or component by different names. This document does not intend to distinguish between components or features that differ in name but not function. The drawing figures are not necessarily to scale. Certain features and components herein may be shown exaggerated in scale or in somewhat schematic form and some details of conventional elements may not be shown in interest of clarity and conciseness.
In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . . ” Also, the term “couple” or “couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection, or through an indirect connection via other devices, components, and connections. In addition, as used herein, the terms “axial” and “axially” generally mean along or parallel to a central axis (e.g., central axis of a body or a port), while the terms “radial” and “radially” generally mean perpendicular to the central axis. For instance, an axial distance refers to a distance measured along or parallel to the central axis, and a radial distance means a distance measured perpendicular to the central axis.
As previously described, continuous tubular conduits, also referred to herein as “tubing,” are typically wound onto a spool to facilitate ease of storage, transportation, and deployment. In many cases, especially in the case of larger diameter and/or more rigid tubing, the winding of the tubing onto the spool imparts a continuous bend or curve into the tubing, which generally follows and conforms with the curvature of the spool onto which the tubing is wound. However, in many applications, it is preferred that the tubing be deployed and installed in a straight or linear fashion (i.e., without bends or curves). Consequently, in such applications it is necessary to reduce or eliminate any bends and curves in the tubing. Typically, straightening devices and operations for tubing requires the use of multiple pieces of relatively large equipment, which undesirably increases the footprint and number of processing steps to deploy and install the tubing. However, embodiments disclosed herein include systems and methods for simultaneously deploying and straightening continuous tubular conduits paid out from spools while minimizing the size and footprint of the associated equipment and operation.

To facilitate appropriate contact between the tubing and rollers 250A, 250B, 250C, 250D, 250E during the above described straightening operations, the height of second roller 250B is adjusted through actuation of actuator 194, the vertical heights of rollers 250C, 250D are adjusted along tie rods 206 through rotation of threaded rods 206′ extending through blocks 204, and the vertical height of roller 250E is adjusted through actuation of actuator 229, all in the manner described above. Specifically, actuator 194 is extended/retracted along axis 197 to ensure that tubing fed from spool 21 is engaged between rollers 250A, 250B. In addition, the vertical position of rollers 250C, 250D is set along tie rods 206 in the manner previously described prior to the initiation of deployment operations to ensure adequate contact between the tubing and rollers 250C, 250D. The pre-set vertical positions of rollers 250C, 250D is influenced by a variety of factors such as, for example, the desired final bend in the tubing (if any), the size (e.g., outer diameter) of the tubing, the rigidity of the tubing, etc. Further, actuator 229 is extended/retracted along axis 225 to achieve a desired level of contact/bending of the tubing as it moves over top of roller 250E. The vertical height of roller 250E and the level of contact/bending of tubing over roller 250E has a notable influence in the resulting straightness of the tubing upon exiting straightening assembly 150. Specifically, in this embodiment, as the vertical separation between the positions of rollers 250C, 250D and roller 250E increases, the amount of bend/curve in the deployed tubing also increases and as the vertical separation between the positions of rollers 250C, 250D and roller 250E decreases, the amount of bend/curve in the deployed tubing also decreases.
