) diameter fasteners with wing nuts. Alternatively, secure the box sections together
using a latching mechanism.
2. Fabricate boxes from aluminum or stainless steel, at least 0.040-inch (1.0 mm) thick.
3. For below ambient services, install a vapor barrier at seams, joints, and
penetrations. Seal between flanges with replaceable gasket material to form a
vapor barrier.
B. Requirements in this Article generally apply to all insulation materials except where more
specific requirements are specified in various pipe insulation material installation articles.
C. Insulation Installation on Straight Pipes and Tubes:
1. Secure each layer of insulation to pipe with tape or bands and tighten without
deforming insulation materials. If furnished in half sections, orient longitudinal joints
at 3 and 9 o'clock positions on the pipe.
2. All insulation shall be tightly butted and free of voids and gaps at all joints.
3. Where vapor barriers are indicated, seal longitudinal seams, end joints, and
protrusions with vapor-barrier mastic and joint sealant.
4. For insulation with factory-applied jackets on above ambient services, secure laps
with outward clinched staples at 6-inches (150 mm) o.c.
5. For insulation with factory-applied jackets on below ambient services, do not staple
longitudinal tabs but secure tabs with additional adhesive as recommended by
insulation material manufacturer and seal with vapor-barrier mastic and flashing
sealant. Vapor barrier must be continuous.
D. Insulation Installation on Pipe Flanges or Mechanical Couplings:
1. Install preformed pipe insulation to outer diameter of pipe flange or mechanical
coupling (such as grooved pipe couplings, if applicable).
2. Make width of insulation section same as overall width of flange/coupling and
bolts, plus twice the thickness of pipe insulation, not to exceed 1½-inch (38-mm)
thickness.
3. Fill voids between inner circumference of flange/coupling insulation and outer
circumference of adjacent straight pipe segments with cut sections of block
insulation of same thickness as pipe insulation.
4. Install jacket material with manufacturer's recommended adhesive, overlap seams
at least 1-inch (25 mm), and seal joints with flashing sealant.
E. Insulation Installation on Pipe Fittings and Elbows:
1. Install preformed sections of same material as straight segments of pipe insulation
when available. Secure according to manufacturer's written instructions.
2. When preformed insulation elbows and fittings are not available, install mitered
sections of pipe insulation, to a thickness equal to adjoining pipe insulation. Secure
insulation materials with wire or bands.
3. Cut sectional pipe insulation to fit. Each piece shall be butted tightly against
adjoining piece and bonded with adhesive. Fill joints, seams, voids, and irregular
surfaces with insulating cement finished to a smooth, hard, and uniform contour
that is uniform with adjoining pipe insulation.
F. Insulation Installation on Valves, Strainers, Unions, and Specials:
1. Insulate valves using preformed fitting insulation or sectional pipe insulation of same
material, density, and thickness as used for adjacent pipe. Overlap adjoining pipe
insulation by not less than two times the thickness of pipe insulation, or one pipe
diameter, whichever is thicker. For valves, insulate up to and including the bonnets,
valve stuffing-box studs, bolts, and nuts. Fill joints, seams, and irregular surfaces with
insulating cement.
2. Arrange insulation to permit access to packing and to allow valve operation
without disturbing insulation.
otherwise indicated.
4. Insulate strainers using preformed fitting insulation or sectional pipe insulation of
same material, density, and thickness as used for adjacent pipe. Overlap adjoining
pipe insulation by not less than two times the thickness of pipe insulation, or one
pipe diameter, whichever is thicker. Fill joints, seams, and irregular surfaces with
insulating cement. Insulate strainers so strainer basket flange or plug can be easily
removed and replaced without damaging the insulation and jacket. Provide a
removable reusable insulation cover. For below-ambient services, provide a design
that maintains vapor barrier.
5. Insulate unions using a section of oversized preformed pipe insulation. Overlap
adjoining pipe insulation by not less than two times the thickness of pipe insulation,
or one pipe diameter, whichever is thicker.
6. Cover segmented insulated surfaces with a layer of finishing cement and coat with
a mastic. Install vapor-barrier mastic for below ambient services and a breather
mastic for above ambient services. Reinforce the mastic with fabric-reinforcing
mesh. Trowel the mastic to a smooth and well-shaped contour.
7. For services not specified to receive a field-applied jacket except for flexible
elastomeric, install fitted PVC cover over elbows, tees, strainers, valves, flanges,
and unions. Terminate ends with PVC end caps. Tape PVC covers to adjoining
insulation facing using PVC tape.
8. Stencil or label the outside insulation jacket of each union with the word “UNION.”

G. Insulate instrument connections for thermometers, pressure gages, pressure temperature
taps, test connections, flow meters, sensors, switches, and transmitters on insulated pipes,
vessels, and equipment. Shape insulation at these connections by tapering it to and
around the connection with insulating cement and finish with finishing cement, mastic,
and flashing sealant.
following:
1. Make removable flange and union insulation from sectional pipe insulation of same
thickness as that on adjoining pipe. Install same insulation jacket as adjoining pipe
insulation.
2. When flange and union covers are made from sectional pipe insulation, extend
insulation from flanges or union long at least two times the insulation thickness over
adjacent pipe insulation on each side of flange or union. Secure flange cover in
place with stainless-steel or aluminum bands. Select band material compatible
with insulation and jacket.
3. Construct removable valve insulation covers in same manner as for flanges except
divide the two-part section on the vertical center line of valve body.
4. When covers are made from block insulation, make two halves, each consisting of
mitered blocks wired to stainless-steel fabric. Secure this wire frame, with its
attached insulation, to flanges with tie wire. Extend insulation at least 2-inches (50
mm) over adjacent pipe insulation on each side of valve. Fill space between
flange or union cover and pipe insulation with insulating cement. Finish cover
assembly with insulating cement applied in two coats. After first coat is dry, apply
and trowel second coat to a smooth finish.
5. Unless a PVC jacket is indicated in field-applied jacket schedules, finish exposed
surfaces with a metal jacket.
I. Special Requirements for Flexible Elastomeric Insulation Installation: Seal all transverse
seams, longitudinal seams, end joints, and section joints with manufacturer's
recommended adhesive to eliminate openings in insulation that allow passage of air to
surface being insulated.
B. Where PVC jackets are indicated, install with 1-inch (25-mm) overlap at longitudinal
seams and end joints; for horizontal applications, install with longitudinal seams along top
and bottom of tanks and vessels. Seal with manufacturer's recommended adhesive.
Apply two continuous beads of adhesive to seams and joints, one bead under lap and
the finish bead along seam and joint edge.
C. Where metal jackets are indicated, install with 2-inch (50-mm) overlap at longitudinal
seams and end joints. Overlap longitudinal seams arranged to shed water. Seal end joints
with weatherproof sealant recommended by insulation manufacturer. Secure jacket
with stainless-steel bands 12-inches (300 mm) o.c. and at end joints.
