Insulation
**************************************************************************
NOTE: If a separate insulation section is part of
this specification, add a note to that section to
indicate that baghouse insulation is covered by this
section.
**************************************************************************
Insulate housing, hopper, and ductwork. Provide insulation with
interruptions to permit access to the following openings without damaging
the insulation system: manholes, inspection doors, access doors, and
flanged openings. Provide boxouts around nameplates and code stamping
symbols. Install a double layer of insulation with the joints of the two
layers staggered. Fill cracks, voids, and depressions of insulation with
insulating cements before applying another layer of insulation or jacket
application. Provide insulation with expansion joints to withstand
differential thermal expansion movements which may cause cracks or tears in
the insulation. Install insulation between stiffeners and over stiffeners
so that the stiffeners are completely insulated. Install additional
insulation or casing spacers between stiffeners so that the surface is
level. Securely wire and lace insulation in place using a soft ASTM A
580/A 580M, Number 14, Type 302 stainless steel wire.
3.3.1.1
Mineral Fiber Block and Board Insulation
Secure mineral fiber and block and board insulation with stud insulation
lugs spaced not greater than 432 mm 17 inches on center. Weld lugs in
place. Reinforce blocks on the exterior face with expanded metal to
prevent sagging or cutting of the insulation by the lacing wire. Secure
