7.3
Place the elbow, tee or other fitting inside of the Yoke (Chart 13
item D-11) of Level and Support as shown in the adjacent picture
and tighten the Clamping Screw (Chart 13 item D-7) with the
provided wrench (Chart 17).
7.4
Mount the short pipe, elbow, tee or other fitting into the Jackbars
of the chain clamp.
7.5
Put the Chain (Chart 13 item D6) of the Level and Support
Device into the Level and Support Device Hook located on
the upper back portion of the Main Block. (Picture at left)
7.6
Rotate the Crank handle (Chart 13 Item D5) clockwise or
counterclockwise until the end of the pipe makes the desired amount of
contact with the end of the mating pipe, fitting, or valve. (Picture on right)
7.7
Loosen the Thumbscrew (Chart 10 item B7) in the Main Block and move the
Universal Jackbars (Chart 10 item B5) to the other side of the weld join
where it is needed and retighten the Thumbscrew
.
7.8
Rotate the Main Block Jackscrews (Chart 10 item B6) and Jackbar Jackscrews
(Chart 8 item A3) until they contact the fit-up pipe.
7.9
Check the relationship of the fit-up pipe to the main pipe to determine
which direction the fit-up pipe must be moved to obtain alignment with the
main pipe.
7.10
Tighten the Jackscrew over high point until the desired outside or inside alignment of the pipes or fittings is
achieved. It will be necessary to loosen the Jackscrew(s) opposite the high point to bring the outside or inside
diameters of the pipes into alignment. This process may need to be repeated with several of the Jackbars until the
correct alignment or reforming is accomplished.
Note:
To check HI-LO on the inside diameter pipes and weld gap, the best tool to use is the Mathey Dearman Q. C.
Welders gauge. English – D253E, Metric – D253M
7.11
The pipes are now ready for welding.
8.0 – FIT-UP OF ELBOW TO PIPE WITH ELBOW FACING DOWNWARD
8.1
Steps 5.1 through 5.18 must be completed before using the following procedure.
8.2
Turn the Crank Handle (Chart 13 item D-5) counterclockwise until the Level and
Support Piston (Chart 13 item D-3) extends out of the Crank Housing (Chart 13
Item D-2) Piston about 1-1/2 to 2 inches.
8.3
Attach the Yoke (Chart 13 item D-11) of the Level and Support Frame to the back of the elbow with a Hold-Down
Clamp part number D244 or D245) as illustrated in the picture at bottom right.
8.4
Mount the elbow into the Jackbars of the Chain Clamp with the elbow facing downward.
WARNING:
The Level and Support Device should never be used as the sole support of
the mating Pipe.
WARNING:
If a solid surface appears in the opening of the
Crank Housing, rotate the Crank Handle clockwise until the
solid surface can no longer be seen.
