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
