Energy Task Force and the PIP IndustryEnergy 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

What is Pre-insulated Pipe ?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)

Why Should You Specify Pre-insulated PipeWhy 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

Pre-insulated Pipe ApplicationsPre-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

Pre-insulated Pipe SpecificationsPre-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

04/18/23Energy Task Force9

Pre-insulated Pipe SpecificationsPre-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

Pre-insulated Pipe SpecificationsPre-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.

Engineering ConsiderationsEngineering 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

Cost Impact of Various PIP SystemsCost 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
