Red Encapsulated Control Line with Close Dimensional Tolerance
Highly Clean and Bright Tubing Surface
Product Description:
MEILONG offers the encapsulation of control lines to provide
increased durability, as well as chemical and corrosion resistance
to meet each project’s specialized requirements, we offer different
encapsulation types, such as: HDPE (High Density Polyethylene),
Santoprene, PVC (Polyvinyl Chloride), Haylar and PVDF
(Polyvinylidene Fluoride).
Encapsulation is a plastic that is extruded over metal tube. It
prevents damage to the metal tubes during the manufacturing
process, and also provides additional abrasion resistance.
Moreover, when cable protectors are installed, encapsulation is
required to enhance the holding force over each production tubing
connection.
Encapsulations are available in a wide range of configurations,
with options of single pass and dual pass encapsulation for added
protection. Flatpacks are widely used when several different lines
are terminated at the same depth in the well. Common application
includes intelligent well systems, deep-set chemical injection
lines with downhole gauge cable and safety valve lines with shallow
set chemical injection lines. For certain applications, bumper bars
are also encapsulated into the flatpack to provide extra crush
resistance.
Control lines are created according to relevant materials’ ASTM
standard. Tubes can be flush, filled, filtered and supplied to meet
client requirements and NAS/SAE standards. Moreover, Encapsulated
Control Lines can meet Potable Water Application requirements.
Features:
When encountering downhole line, maximum protection should be put
forth. This includes the installation of mechanisms that increase
its crush resistance. Additionally, there is a need to protect the
control line from potential abrasion and pinching that may be
inflicted upon it. It is essential to take precautionary steps to
reduce stress corrosion failures that may occur in the long-term.
Lastly, when clamping the line, its profile should be improved.
Single or multiple casing techniques can be used to make the
running of it easier, all the while ensuring added protection.

Applications:
When operating an oil & gas facility, down hole tubes, subsea
umbilicals, process constructions and general control systems are
essential elements for a successful operation. Specifically, down
hole tubes are used to maintain the wellhead pressure, subsea
umbilicals help connect a wide variety of parts and control systems
underwater, process constructions are mainly used to accomplish the
design requirements from clients and the general control systems
help monitor and control any process in the facility. In addition,
steam supply lines and gas transport lines are used for the supply
of steam or gas in the optimal condition. Lastly, instrumentation
systems are used to monitor the data of the process to ensure
safety and reliability of the whole system.
