Encapsulated Tubing
TPV Encapsulated Duplex Stainless Steel Control Line
10000M
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

Meilong Tube specially manufactures seamless and redrawn, welded and redrawn coiled tubing which are made from corrosion-resistant austenitic, duplex, super duplex stainless steels and nickel alloy grades. The tubing is used as hydraulic control lines and chemical injection lines specially serving oil and gas, geothermal industry.
Typical size
Outside diameter of control lines is mainly 1/4’’ (6.35mm).
Wall thicknesses: 0.035’’ (0.89mm), 0.049’’ (1.24mm), 0.065’’ (1.65mm)
Control line tubing is available in lengths from 400 feet (122 meters) to 32,808 feet (10,000 meters). No orbitally butt welds.
Other specifications (1/8’’ to 3/4’’) are available on request.
Important
Each one tubing coil is a completely continuous length without orbital welds.
Each one tubing coil is hydrostatic tested at minimum 10,150 psi.
The test can be witnessed on site by the third party inspectors (SGS, BV, DNV).
Other tests are eddy current test, chemicals, flattening, flaring, tensile, yield, elongation, hardness for the material quality.
