extending the life of your pipelines, thus increasing operation efficiency in low cost enviroment

1. Internal Coating
Sarah Tamilarasan

2. Chemical costs -$55-60k/year (Paraffin & Corrosion)
Pigging - $12,000/year (once a month)
Operationally intensive
Internally coat pipe - $25-15/ft

4. 4
Hydraulic Efficiency
(Reduced surface profile = less friction loses)
Flow Assurance
(Reduced surface profile = reduction in
mechanical binding properties)
Flow Assurance
(Low Surface Energy =
reduction in chemical
binding properties)

5. • Carrizo used TK-70
• Rated 225 F
• Epoxy with great flexibility
and chemical resistance
• Ideal for gathering and
transmission lines

• Metal to metal connectionZap-lok
• Zaplok - $6/ft
• Welding varied from $26/ft-$11/ft
Economics for
welding vs.
Zap-lok
• 5 days of welding equivalent to 3 days using
zaplok
• Saved approx. 30% -40% in construction time
Construction
was faster
