SEALANT
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 four 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 re-drawn tight within four hours of first application of Silastic to the joint.
13.
Tie rods must be installed in lugs immediately after
draw-up is complete.
a. Insert tie rods through the lugs on the front
back sections. Place regular steel nuts & flat
washers on both ends of rods and tighten finger
tight.
Do not overtighten tie rods. Steel nuts should be
finger tight only to prevent section damage due to
thermal expansion.
b. Remove draw rod assembly from the sections and
remove the draw rod couplings from the tie rods.
