Pipe Preparation and Marking
The pipe is prepared in the same manner as
previously discussed for SMFs. Use the multipurpose
marking gauge (fig. 16-28) to verify the pipe end
squareness and pipe outside diameters. Check the pipe
diameters at two points 90 degrees apart to get true
dimension readings. After obtaining acceptable pipe
diameters, use an indelible marking pen to mark the
installation and inspection markings.
Installation and Inspection
Installation of the ESP fittings is an easy and quick
process. Slide the fitting onto one pipe end. It should
slide easily over the pipe end. DO NOT FORCE the
fitting over the pipe end because the sealing surface
could be damaged or scratched. Align the fitting on the
installation mark as shown in figure 16-29. Using the
locking power head and following the manufacturer's
instructions, lock the fitting onto the pipe. Remove the
tool head and inspect the installation. The swage fitting
should be checked for the following criteria (as shown
in fig. 16-30).
The swage ring should be seated against the
fitting body tool.
The inboard inspection marks should be partially
covered by the fitting body.
The fitting body should extend from underneath
the ESP fitting.
If the fitting fails inspection, the joint should be cut
out and replaced.
SHAPING TUBING AND PIPE
Bending is the shaping operation that you probably
Figure 16-26.--Using marking/inspection gauge for pipe/
will use the most when working with tubing or pipe.
Other shaping operations include flaring tube ends,
