Orange County West Campus Office Building -HVAC <br />PDC Project 23020 Sleeves and Sleeve Seals for HVAC <br />Piping 23 05 17 - 2 <br />1.Advance Products &Systems,LLC​​ <br />2.Flexicraft Industries​​ <br />3.GPT Industries <br />4.Or Approved Equal <br />B.Modular Mechanical Sleeve-Seal: <br />1.Elastomer-based interlocking links continuously fill annular space between pipe and wall- <br />sleeve,wall or casing opening. <br />2.Watertight seal between pipe and wall-sleeve,wall or casing opening. <br />3.Size and select seal component materials in accordance with service requirements. <br />4.Service Requirements: <br />a.Corrosion resistant. <br />b.Oil,fuel,gas,and solvent resistant. <br />c.Underground,buried,and wet conditions. <br />d.High Temperature,up to 400 degrees F. <br />e.Low temperature,down to minus 67 degrees F. <br />5.Glass-reinforced plastic pressure end plates. <br />C.Sealing Compounds: <br />1.Provide packing and sealing compound to fill pipe to sleeve thickness. <br />2.Combined packing and seal compound is to match partition fire-resistance hourly rating. <br />PART 3 EXECUTION <br />3.01 PREPARATION <br />A.Ream pipe and tube ends. Remove burrs. Bevel plain end ferrous pipe. <br />B.Remove scale and foreign material,from inside and outside,before assembly. <br />3.02 INSTALLATION <br />A.Route piping in orderly manner,plumb and parallel to building structure. Maintain gradient. <br />B.Install piping to conserve building space,to not interfere with use of space and other work. <br />C.Install piping and pipe sleeves to allow for expansion and contraction without stressing pipe,joints, <br />or connected equipment. <br />D.Inserts: <br />1.Provide inserts for placement in concrete formwork. <br />2.Provide inserts for suspending hangers from reinforced concrete slabs and sides of <br />reinforced concrete beams. <br />3.Where concrete slabs form finished ceiling,locate inserts flush with slab surface. <br />4.Where inserts are omitted,drill through concrete slab from below and provide through-bolt <br />with recessed square steel plate and nut above slab. <br />E.Structural Considerations: <br />1.Do not penetrate building structural members unless approved by the Structural Engineer. <br />F.Provide sleeves when penetrating footings,floors,and walls. Seal pipe including sleeve <br />penetrations to achieve fire resistance equivalent to fire separation required. <br />1.Aboveground Piping: <br />a.Pack solid using mineral fiber in compliance with ASTM C592. <br />b.Fill space with an elastomer caulk to a depth of 0.50 inch where penetrations occur <br />between conditioned and unconditioned spaces. <br />2.Caulk exterior wall sleeves watertight with lead and oakum or mechanically expandable <br />chloroprene inserts with mastic-sealed components. <br />G.Manufactured Sleeve-Seal Systems: <br />1.Install manufactured sleeve-seal systems in sleeves located in grade slabs and exterior walls <br />at piping entrances into building. <br />Docusign Envelope ID: 8DED1454-68D2-4E36-9FC6-E56FF2124E5D
