Manual Draw-Up Tie Rod Pattern

WARNING

When tightening the draw-up nuts, DO NOT EXCEED 150 FT-LB OF TORQUE. If the maximum torque limit has been reached and a gap greater than .025” still exists between the sections, consult the regional office.

KEEP NIPPLES ALIGNED WITH NIPPLE PORTS. If necessary, tap edge of nipples lightly with a blunt tool or rod to keep nipples from cocking while sections are being drawn-up. DO NOT DRAW UP SECTION WHEN NIPPLES ARE COCKED. If the torque required becomes excessive, periodically place a heavy block of wood over each nipple port and strike as squarely as possible with several blows to relieve tension on the draw-up rods.

n.CONTINUE ASSEMBLING SECTIONS IN THEIR RESPECTIVE ORDER alternating draw-up rods from the upper to lower set of holes in draw-up lugs (see Figure 13). Be certain that all sections are drawn up iron-to-iron at all three (3) nipple ports.

BE SURE TO APPLY THE SEALANT to the groove in the ground joints between adjacent sections as the boiler operates with a positive pressure in the firebox and products of combustion will escape between sections unless the sections are properly sealed. The sealant should be applied before each section is placed on the assembly.

o.If a joint springs apart it must be redrawn tight within four (4) hours of the time of application of Silastic to that joint.

p.EXCESS LENGTH OF DRAW-UP RODS must not extend beyond front and rear section to ensure proper fit of jacket, adjust accordingly.

q.After all sections have been drawn up, the draw-up rod nuts should be loosened until finger tight and then tightened ½ turn with a wrench.

r.Now Proceed to Paragraph C of this Section, Hydrostatic Test.

2.ASSEMBLY OF SECTIONS (HYDRAULIC DRAW-UP)

The entire boiler assembly may be drawn up at one time using hydraulic draw-up equipment providing the operation is completed within two (2) hours after application of the sealant.

a.Repeat steps 1a through 1k under “Field Assembled Sections (Manual Draw-Up).”

b.Continue driving sections in place (in their respective order) until all sections are in the assembly. Ground surfaces between adjoining sections should be spaced 1/4” to 3/8” apart. Spacing of more than 3/8” will limit number of sections that can be drawn up in one unit and could indicate cocked nipples.

WARNING

Sealant must be properly applied to ALL boiler joints. Failure to properly seal the boiler joints will result in combustion gas leaks through to joint. DO NOT operate boiler with combustion gas leaks. The sealant should be applied before each section is placed on the assembly.

On long boiler assemblies, it may be necessary to draw-up a partial block if the entire boiler is not ready to be drawn-up tight within two (2) hours of the first application of Silastic. If the block assembly time extends overnight, the partial block completed must be drawn-up tight before leaving the boiler overnight. If a joint springs out, it must be redrawn tight within four (4) hours of first application of Silastic to the joint.

c.Insert the three (3) ¾” draw-up rods (and couplings, if appropriate) through the tapped holes in the rear section extending them through the tapped holes in the front section. Be sure to screw draw-up rods into couplings far enough to prevent stripping threads.

d.Place a 3” x 12” lg. steel channel on each end of the upper draw-up rod and a 3” x 8½” lg. steel channel on each end of the lower draw-up rods.

Refer to Figures 10 and 11 for proper placement of channel block during assembly procedures. Install nuts and washers on one end of the draw- up rods and the hydraulic rams, washers and
