Encapsulated Tubing
TPV Encapsulated Incoloy Alloy 825 Chemical Injection Line
10000M
ENCAPSULATED CONTROL LINE
Encapsulation is a plastic that is extruded over metal tube. Encapsulation prevents damage to the metal tubes during the manufacturing process. The encapsulation also provides additional abrasion resistance and is required if cable protectors are installed to enhance the holding force over each production tubing connection.
Encapsulations are available in a wide range of configurations with options of single pass encapsulation and dual pass encapsulation for added protection.
APPLICATION
Flatpacks are commonly used when several different lines are terminated at approximately the same depth in the well.
Common applications include intelligent well systems, deep-set chemical injection lines with downhole gauge cable and safety valve lines with shallow set chemical injection lines. For some applications bumper bars are also encapsulated into the flatpack to provide additional crush resistance.
STANDARDS & APPROVALS
Control Lines are manufactured according to applicable ASTM standards for each specific material.
Tubes can be supplied flushed, filled, and filtered per client requirements and to the appropriate NAS/SAE standards.
QUALITY & TESTING
- Manufactured in accordance with Standard Inspection and Quality Plans
DESIGN & CONSTRUCTION
- Encapsulation for single line
- Encapsulation profiles to suit customer application
- Custom Line Marking
- Full range of application materials
ENCAPSULATION MATERIALS
- PP (Polypropylene) /TPR (Santoprene) / PA
(Nylon) / PVDF / ETFE (Tefzel) / ECTFE (Halar)
FEP / PFA / ECA 3000
