Energy Task Force Pre-insulated Piping Systems

1. Energy Task ForcePre-insulated Piping Systems TLC Engineering for Architecture July 23, 2012 Energy Task Force

2. 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

3. 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. 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

5. 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

6. Specify Pre-insulated Pipe Energy Task Force

7. 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

8. 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

9. 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

10. 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

14. Typical Specification – Field Insulated Steel Energy Task Force

15. 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

16. 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
