Agenda Energy Task Force and the PIP Industry Why should the Engineer Specify PIP Applications for Pre-insulated Pipe Pre-insulated Pipe Specifications Engineering Considerations Cost Impact of Various PIP Systems Q & A Energy Task Force 4/16/2017

Energy Task Force and the PIP Industry ETF 29 Years of Experience Current 2 Manufacturing Locations Orlando, FL and Phoenix, AZ PIP Young Industry Need for alternative to Field Insulated Pipe Rovanco / Ricwil (now Perma Pipe) 1st Players Active in Florida / SE US Energy Task Force Rovanco Permapipe Thermacore Process Engineers Welcome at our Plant! Energy Task Force 4/16/2017

What is Pre-insulated Pipe ? ANY pipe that carries a Fluid can be insulated under Factory conditions at Energy Task Force Carbon steel Copper Gasket joint PVC Glue joint PVC Ductile iron Stainless steel High density polyethylene(HDPE) Fiberglass reinforced polyester(FRP) ½” to 30” ETF insulates the pipe with polyurethane foam and protects the insulation with various outer casings(PVC, HDPE, Steel, Aluminum) Energy Task Force 4/16/2017

Why Should You Specify Pre-insulated Pipe Pipe Insulated under Factory Consistent Conditions Field Insulated Pipe is subject to Jobsite Conditions PIP Saves $$$ in Underground Applications PIP Saves Time in Aboveground Applications Cost is slightly higher for PIP Energy Task Force 4/16/2017

Specify Pre-insulated Pipe Energy Task Force 4/16/2017

Pre-insulated Pipe Applications 80% of all Pre-insulated Pipe Projects Schools Universities Hospitals Prisons Types of applications Chilled Water Hot Water Steam and Condensate Domestic Water Cryogenic Below ground and Above ground Applications Energy Task Force 4/16/2017

Pre-insulated Pipe Specifications Carrier Pipe Steel is Recommended for Underground Installations Less Sensitivity to Installing Contractor Less liability for Engineer and ETF Cost add to other systems is minimal to a wash Have to consider expansion compensation for HW and steam systems Copper for 2” and smaller Pipe Push Joint PVC Very Installation Sensitive Settling over time can result in joint leakage Short term (ETF) and Long Term (Engineer) Liability versus Steel Must transition to Steel under Slab Glue Joint PVC not recommended Ductile Iron excellent alternative for Large Bore Pipe HDPE pipe excellent alternative for Chilled Water Energy Task Force 4/16/2017

Pre-insulated Pipe Specifications Insulation – Polyurethane Foam is Industry Standard 1” of Polyfoam = 3” of foam glass Jacket Selection PVC is industry standard jacket up to 12” Pipe HDPE is industry standard for 14” and larger Pipe Aluminum excellent choice for Above Ground Appl. Galvanized steel another alt for Above Ground Joining Methods Steel – Butt weld Below Ground Steel – BW or Victaulic Above Ground Ductile Iron – Mechanical Joint Much Faster Install versus Steel in Large Bore Pipe Push Joint PVC – Bell & Spigot Energy Task Force 4/16/2017

Pre-insulated Pipe Specifications Prefab Systems versus Field Insulated Fittings Specify Manufacturer Pre-fabricated / Pre-insulated Fittings only When nothing else in the ground 14” and Above Pipe If you have concerns with the installing contractor Specify Field Insulated Fittings all other cases Significantly less expensive versus prefab systems Half # of welded joints versus prefab system More versatile in renovation projects when underground obstacles are inevitable. ALWAYS SPECIFY FIELD SERVICE BY THE MANUFACTURER TO INSURE THE QUALITY OF FIELD INSULATED FITTINGS. Lets Look at Some Examples Energy Task Force 4/16/2017

Engineering Considerations Push Joint PVC Systems Underground B & S Operation Handles Exp/Contr Comp MUST transition to Steel under Slab MUST insure your Spec is followed Trench Preparation is critical Hydro Testing is a Challenge DO NOT insulate fittings if Thrust Blocked Steel / Copper Systems Underground Expansion compensation MUST be considered for HW and Steam Systems Insist on PIP Manufacturer Drawing for Hot Water and Steam Systems CHW Systems – Can Usually FLOAT Energy Task Force 4/16/2017

Cost Impact of Various PIP Systems Above Ground Systems Steel with Aluminum Jacket Steel with Galvanized Steel Jacket Steel with UV Inhibitor PVC Jacket Specify Victaulic if Roof Install Under Ground Systems Steel / Copper Prefabricated System Steel / Copper “Sticks & Kits” HDPE – CHW Only Push Joint PVC – CHW Only Solvent Weld PVC – CHW Only Energy Task Force 4/16/2017
