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)

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

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

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

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

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.

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

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
