<br /> PLUMBING PIPING INSULATION 15085-8
<br />
<br />
<br />
<br /> adjoining piece and bonded with adhesive. Fill joints, seams, voids, and irregular surfaces
<br />with insulating cement finished to a smooth, hard, and uniform contour that is uniform with
<br />adjoining pipe insulation.
<br />3. Insulate tee fittings with preformed fitting insulation or sectional pipe insulation of same
<br /> material and thickness as used for adjacent pipe. Cut sectional pipe insulation to fit. Butt each
<br /> section closely to the next and hold in place with tie wire. Bond pieces with adhesive.
<br />4. Insulate valves using preformed fitting insulation or sectional pipe insulation of same
<br /> material, density, and thickness as used for adjacent pipe. Overlap adjoining pipe insulation
<br />by not less than two times the thickness of pipe insulation, or one pipe diameter, whichever is
<br />thicker. For valves, insulate up to and including the bonnets, valve stuffing-box studs, bolts,
<br />and nuts. Fill joints, seams, and irregular surfaces with insulating cement.
<br />5. Insulate strainers using preformed fitting insulation or sectional pipe insulation of same
<br /> material, density, and thickness as used for adjacent pipe. Overlap adjoining pipe insulation
<br /> by not less than two times the thickness of pipe insulation, or one pipe diameter, whichever is
<br />thicker. Fill joints, seams, and irregular surfaces with insulating cement. Insulate strainers so
<br />strainer basket flange or plug can be easily removed and replaced without damaging the
<br />insulation and jacket. Provide a removable reusable insulation cover. For below-ambient
<br />services, provide a design that maintains vapor barrier.
<br />6. Insulate flanges and unions using a section of oversized preformed pipe insulation. Overlap
<br />adjoining pipe insulation by not less than two times the thickness of pipe insulation, or one
<br />pipe diameter, whichever is thicker.
<br />7. Cover segmented insulated surfaces with a layer of finishing cement and coat with a mastic.
<br /> Install vapor-barrier mastic for below-ambient services and a breather mastic for above-
<br /> ambient services. Reinforce the mastic with fabric-reinforcing mesh. Trowel the mastic to a
<br /> smooth and well-shaped contour.
<br />8. For services not specified to receive a field-applied jacket except for flexible elastomeric and
<br /> polyolefin, install fitted PVC cover over elbows, tees, strainers, valves, flanges, and unions.
<br /> Terminate ends with PVC end caps. Tape PVC covers to adjoining insulation facing using
<br /> PVC tape.
<br />9. Stencil or label the outside insulation jacket of each union with the word "union." Match size
<br /> and color of pipe labels.
<br />
<br />C. Insulate instrument connections for thermometers, pressure gages, pressure temperature taps, test
<br /> connections, flow meters, sensors, switches, and transmitters on insulated pipes. Shape insulation
<br /> at these connections by tapering it to and around the connection with insulating cement and finish
<br /> with finishing cement, mastic, and flashing sealant.
<br />
<br />D. Install removable insulation covers at locations indicated. Installation shall conform to the
<br /> following:
<br />1. Make removable flange and union insulation from sectional pipe insulation of same thickness
<br /> as that on adjoining pipe. Install same insulation jacket as adjoining pipe insulation.
<br />2. When flange and union covers are made from sectional pipe insulation, extend insulation
<br /> from flanges or union long at least two times the insulation thickness over adjacent pipe
<br /> insulation on each side of flange or union. Secure flange cover in place with stainless-steel or
<br /> aluminum bands. Select band material compatible with insulation and jacket.
<br />3. Construct removable valve insulation covers in same manner as for flanges, except divide the
<br /> two -part section on the vertical center line of valve body.
<br />4. When covers are made from block insulation, make two halves, each consisting of mitered
<br /> blocks wired to stainless-steel fabric. Secure this wire frame, with its attached insulation, to
<br /> flanges with tie wire. Extend insulation at least 2 inches
<br /> side of valve. Fill space between flange or union cover and pipe insulation with insulating
<br /> over adjacent pipe insulation on each
<br /> cement. Finish cover assembly with insulating cement applied in two coats. After first coat is
<br /> dry, apply and trowel second coat to a smooth finish.
<br />5. Unless a PVC jacket is indicated in field-applied jacket schedules, finish exposed surfaces
<br /> with a metal jacket.
