Steam supply lines
Gas transport lines
Instrumentation

Features of Encapsulated Control Line:
Maximize protection of downhole line
Increase crush resistance during installation
Protect control line against abrasion and pinching
Eliminate long term stress corrosion failure of control line
Improve clamping profile
Single or multiple encapsulation for ease of running and added protection

Encapsulation Materials:
Polypropylene -25C to 150C Good resistance to brines
Santoprene -30C to 150C Good resistance to brines
Nylon 11 -60C to 135C Good resistance to hydrocarbons, good abrasion resistance
PVDF -30C to 150C Good resistance to brines and hydrocarbons, good abrasion resistance
FEP -110C to 200C Good resistance to brines and hydrocarbons
