Abstract

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. Additionally, the system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch on the grab ring to facilitate securing the pipe fitting to the swage machine, a die plate in which a die is loaded, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via a forward stroke.

First claim

What is claimed is:

1. A system comprising:
a pipe fitting configured to be secured to a pipe segment, wherein the pipe fitting comprises:
a grab ring having a grab notch; and
a fitting jacket configured to be conformally deformed around tubing of the pipe segment that defines a pipe bore and a fluid conduit implemented in a tubing annulus of the tubing to facilitate securing the pipe fitting to the pipe segment; and

a swage machine, wherein the swage machine comprises:
a grab plate having a grab tab configured to matingly interlocked with the grab notch on the grab ring of the pipe fitting to facilitate securing the pipe fitting to the swage machine;
a die plate in which a die is loaded;
a swaging actuator secured to the die plate, wherein the swage machine is configured to operate the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via one or more forward strokes;
a support plate, wherein the die plate of the swage machine is disposed between the grab plate and the support plate of the swage machine and the swaging actuator is secured between the support plate and the die plate of the swage machine; and
a support rod secured to the grab plate and the support plate of the swage machine such that the support rod extends through the die plate of the swage machine to enable the die plate to slide between the grab plate and the support plate.

2. The system of claim 1 , wherein:
the die is loaded in the die plate of the swage machine such that the die opens toward the grab plate of the swage machine; and
the swage machine is configured to operate the swaging actuator to push the die plate over the fitting jacket of the pipe fitting in an inwardly axial direction toward the grab plate of the swage machine to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment.

3. The system of claim 1 , wherein the swaging actuator of the swage machine comprises a hydraulic actuator or a pneumatic actuator.

4. A method of operating a swage machine, comprising:
loading a die to be used to conformally deform a fitting jacket of a pipe fitting around tubing of a pipe segment in a die plate of the swage machine at least in part by loading the die in the die plate such that the die opens toward the grab plate of the swage machine;
loading a portion of a pipeline system comprising the pipe fitting into the swage machine such that a grab tab on a grab plate of the swage machine matingly interlocks with a grab notch on a grab ring of the pipe fitting to facilitate securing the swage machine to the pipe fitting;
engaging the die loaded in the die plate of the swage machine with the portion of the pipeline system loaded in the swage machine; and
operating a swaging actuator secured to the die plate of the swage machine to push the die plate over the fitting jacket of the pipe fitting such that the die loaded in the die plate conformally deforms the fitting jacket around the tubing of the pipe segment at least in part by operating the swaging actuator to push the die plate over the fitting jacket of the pipe fitting in an inwardly axial direction toward the grab plate of the swage machine via one or more extending strokes to facilitate securing the pipe fitting to the pipe segment.

5. The method of claim 4 , wherein:
loading the die in the die plate of the swage machine comprises transitioning the swage machine from a closed state in which a housing lid of the swage machine is closed onto a housing body of the swage machine to an opened state in which the housing lid is opened from the housing body; and
engaging the die loaded in the die plate with the portion of the pipeline system loaded in the swage machine comprises transitioning the swage machine from the opened state in which the housing lid is opened from the housing body to the closed state in which the housing lid is closed onto the housing body.

6. The method of claim 4 , wherein engaging the die loaded in the die plate of the swage machine with the portion of the pipeline system loaded in the swage machine comprises operating a die actuator secured between a plate rim of the die plate and the die to extend the die in an inwardly radial direction.

7. A method of operating a swage machine, comprising:
loading a die to be used to conformally deform a fitting jacket of a pipe fitting around tubing of a pipe segment in a die plate of the swage machine at least in part by transitioning the swage machine from a closed state in which a housing lid of the swage machine is closed onto a housing body of the swage machine to an opened state in which the housing lid is opened from the housing body;
loading a portion of a pipeline system comprising the pipe fitting into the swage machine such that a grab tab on a grab plate of the swage machine matingly interlocks with a grab notch on a grab ring of the pipe fitting to facilitate securing the swage machine to the pipe fitting;
engaging the die loaded in the die plate of the swage machine with the portion of the pipeline system loaded in the swage at least in part by transitioning the swage machine from the opened state in which the housing lid is opened from the housing body to the closed state in which the housing lid is closed onto the housing body; and
operating a swaging actuator secured to the die plate of the swage machine to push the die plate over the fitting jacket of the pipe fitting such that the die loaded in the die plate conformally deforms the fitting jacket around the tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment via one or more extending strokes.
