2. Encapsulated Control Line

 

Encapsulation of control line is to encapsulate the control line with special material. It can increase

durability, as well as chemical and corrosion resistance in order to meet specialized requirements for each project.

 

Different encapsulation types, such as: 

FEP (Fluorinated Ethylene Propylene)

PVC (Polyvinyl chloride)
