1 COMPOSITE USAGE IN THE PIPELINE INDUSTRY TAMMY BOMIA

2 OUTLINE What is a Composite Field Applied ARO Pipeline Integrity ASME PCC2, Article 4.1 Conclusion

3 WHAT IS A COMPOSITE? Various Laminates

4 FIBER-REINFORCED FIELD APPLIED ARO

5 HDD / BORING COATING DAMAGE High Profile of Girth Welds Field Application Aggressive Soil Conditions Bending Load Jobsite Hazards

6 Factory Applied ARO Field Applied ARO

7 FIBER REINFORCED ARO Truly Sacrificial Fiber-Reinforced Impact, Abrasion & Gouge Resistant Controlled Cure Profile Field Friendly

8 CASE STUDY 6 OD Pilot Cold tape with fiber reinforced ARO Two Part Liquid Two Part Liquid Reinforced

9 CASE STUDY 24 OD Natural Gas Pipeline Pulled Back twice and coating damage was unacceptable. Using a fiber reinforced ARO, the third pullback passed inspection.

10 CASE STUDY 12 OD Pipeline Visco Elastic Coating

11 CASE STUDY 36 OD Ductile Iron Water pipe pulled back Fiber reinforced ARO was used to Prevent peel back on these heat shrink sleeves

12 CASE STUDY 26 OD Crude Pipeline Saudi Aramco evaluated several coatings & ARO s A Two Part Liquid, fiber reinforced Corrosion Coating & ARO was specified

13 CASE STUDY Fun Fact: Camels are a nuisance on pipeline projects in the middle east!
