Orange County West Campus Office Building -HVAC <br />PDC Project 23020 HVAC Piping Insulation 23 07 19 - 4 <br />5.Cover inserts with jacket material matching adjacent pipe insulation.Install shields over <br />jacket,arranged to protect jacket from tear or puncture by hanger,support,and shield. <br />I.Inserts and Shields: <br />1.Shields: ​Galvanized steel​,20 gauge,one half the circumference of the insulation,and a <br />minimum of 12 inches long,between pipe hangers or pipe hanger rolls and inserts. <br />2.Insert location: Between support shield and piping and under the finish jacket. <br />3.Insert Configuration: Minimum 6 inches long,of same thickness and contour as adjoining <br />insulation;may be factory fabricated. <br />4.Insert Material: Hydrous calcium silicate insulation or other heavy density insulating material <br />suitable for the planned temperature range. <br />J.Continue insulation through walls,sleeves,pipe hangers,and other pipe penetrations. Finish at <br />supports,protrusions,and interruptions. At fire separations,see Section 07 84 00. <br />K.Pipe Exposed in Mechanical Equipment Rooms: Finish with PVC jacket color coded to piping <br />system.Refer to 23 05 53 for colors. <br />L.Pipe Exposed in Finished Spaces:Finish with canvas jacket sized for finish painting.Canvas shall <br />be coated twice with Foster fireproof lagging to ensure specified flame and smoke spread ratings. <br />M.For refrigerant line sets and condensate piping exposed to view serving wall mounted units, <br />provide lineset cover system.Speedichannel by DiversiTech,Hide-A-Line by DuctlessAire,or <br />equivalent by Inaba Denko. <br />N.Exterior Applications: Provide vapor barrier jacket. Insulate fittings,joints,and valves with <br />insulation of like material and thickness as adjoining pipe,and finish with glass mesh reinforced <br />vapor barrier cement. Provide with 0.016 inch aluminum rolled jacket.Cover with aluminum jacket <br />with aluminum bands 12 inches on center and at each butt joint located on bottom side of <br />horizontal piping.Fittings shall be covered with two piece factory fabricated "ELL-JACS." <br />O.All exposed piping surfaces,insulation,supports,etc.,shall be painted with two coats of oil base <br />paint.Color shall be selected by the Owner. <br />P.Insulation systems shall be installed per the applicable plate from the MICA manual 8th edition: <br />1.Pre-formed Pipe Insulation Single Layer Construction:Plate 1-100 <br />2.Flexible Foam Insulation:Plate 1-200 <br />3.Field applied Metal Jacketing:Plate 1-400 <br />4.Non-metallic sealed jacketing systems:PVC,etc:Plate 1-510 <br />5.Split Ring Hangers:Plate 1-600 <br />6.Clevis Hanger with High Density Inserts:Plate 1-610 <br />7.Pre-Insulated Pipe Support,Standoff Clamp:Plate 1-640 <br />8.Vapor Stop (Dam)-Pipe:Plate 1-660 <br />9.Refrigerant and Low Temperature:Plate 1-801 <br />10.Traced Piping:Plate 1-900 <br />11.Pre-formed Elbow Insulation:Plate 2-100 <br />12.Mechanical Fitting Field Fabricated:Plate 2-116 <br />13.Pre-formed or Fabricated Tee Insulation:Plate 2-120 <br />14.Field or Factory-Fabricated Valve Insulation:Plate 2-130 <br />15.In-line Flange Insulation Built-up and Beveled:Plate 2-135 <br />16.Flexible Foam Fittings:90s and 45s:Plate 2-200 <br />17.Flexible Foam Fittings,Ts:2-220 <br />18.Flexible Foam Ts:Plate 2-225 <br />19.PVC/Insert Valve Insulation:Plate 2-530 <br />20.PVC/Insert Mechanical Coupling on In-line Flange:Plate 2-535 <br />21.Non-metallic Jackets:Fitting and Valve Insulation Sealed Jacketing Systems:Plate 2-536 <br />22.PVC End Cap Over Insulation:2-540 <br />23.Vapor Stop (Dam)-Fittings:Plate 2-660 <br />24.Vapor Stop (Dam)-Equipment:4-660 <br />3.03 SCHEDULE <br />Docusign Envelope ID: 8DED1454-68D2-4E36-9FC6-E56FF2124E5D
