1. Thermoflex® Tubing
Reinforced Thermoplastic
Gathering, Disposal and
Injection Lines
Overview
June 11, 2012

2. Polyflow LLC
• Design Manufacture and Market Reinforced
Thermoplastic Pipe and Tube for the Oil and
Gas Industry
• Significantly Reduce the Capital Costs Required
for Downhole Tubulars and Surface Piping
• Minimize Corrosion and Resultant
Environmental Concerns with Piping Systems

3. Unique Competencies
• Multi-layer Extrusion Capability
– Bond Polymers That don’t “like” each other
– Achieve Properties At a Minimal Cost
• Braiding/ Reinforcement Technology
– “Net Neutral Braid” Technology
– Strength with 10% of the braid
– Aramid Fibers

4. What makes Polyflow Unique ?
• Nylon and Polyphenylene Liners
• Extremely Lightweight and Flexible Eliminating
Conventional Equipment
• Superior Cyclical Loading Performance
• Pull Through Existing Pipelines with Tight
Clearances and Bends

5. Key Considerations for Thermoflex®
Surface Lines
• Liner Compatibility with Fluids
• Water only – HDPE
• Water with Hydrocarbons, CO2 - Nylon
• Water with Hydrocarbons, CO2, H2S - PPS
• Bonded Liners to Minimize Collapse Resistance
• Aramid Fibers to Withstand Cyclic Loading
• Flow Rate Requirements Can reduce Pipe
Diameter and Costs
• Low Cost Rapid Installation and Repair to
Reduce Capital Costs.

6. Liner Construction & Design
• Multi-layer Design
– Inner Liner
• Corrosion Resistance Inner Barrier
• Low Permeation
• No Softening /Swelling
– Polymer Selection
• Nylon . . Hydrocarbons,
CO2, Brine Outer Strength and
• PPS . . . Hydrocarbons, Abrasion Layer
CO2, Brine, H2S
• Keeps Costs Attractive

7. Reinforcement Layer
Considerations
• Multi-layer Design
– Cross Braids Provide
Axial Strength
– Longitudinal Braids
Provide Tensile
Strength to Minimize
Stretch
– Aramid Fibers for
Fatigue and Strength
• Tubing Strength
P=(2*F*n)/D*L

8. Reinforcement Options
Aramid Steel Glass
Strength High Medium High
Cyclic Loading Excellent Excellent Poor
H20 Environment Excellent Good Poor
CO2/H2S Good Poor Good
Rapid Impact Good Good Poor

9. UV Protection
• Not Resistant Forever
• Prefer TiO2 package
– White keeps pipe cooler
than black
– Long term Data on the
additives to the plastic
• Does not help in Fire

10. Couplings and Terminations
• Required for Each End
of the Tubing
• Threaded, Weld, &
Flange Styles Available
• Zinc Chromate Plated
Carbon or Duplex
Stainless Steel
• Joint less Unions

11. Eliminating Welding
• Pre-fab Risers
– Shop Fabricated
– Pre Tested
– Any Configuration
• Couples Right to
Thermoflex Tubing

12. Tools For Coupling
• Portable Coupling
Machines (250lbs)
• Up to 4.5”
• For Termination and
Union Couplings
• 10,000PSI Hydraulic
Pump

13. Delivery of Tubing
• Comes on Spools
• Length Dependent
Upon OD and
Pressure Rating
• Spools are
disposable
– No Deposit, No Return
– Easy to Break Down

14. Installation Methods
• Direct Bury
• Continuous Plowing
• Trenching
• Pulled Through
Existing Steel Pipe
– Sizing Dependent Upon
Restrictions in Steel
– Pig with wire line and
pull pipe
