Meilong Tube's downhole control lines are designed to provide the
utmost durability and resistance to extreme conditions. They are
primarily used as transmission conduits for command and operation
of hydraulic devices in oil, gas and water-injection wells. These
control lines are customizable according to different applications
and downhole components, allowing for greater versatility.
The selection of materials is based on two variables: what is the
bottomhole temperature, and how strong is the underlying pressure.
The material must display optimum strength in terms of tensile and
tear strength, water absorption, gas permeability, oxidation, and
abrasion and chemical resistance. Additionally, it must be
hydrolytically stable and be compatible with regular well
completion fluids.
To ensure high quality, these control lines have passed extensive
testing. This includes crush testing and simulation of
high-pressure wells in autoclaves. As established by the
laboratory's tests, the use of wire-strand “bumper wires” provides
increased structural load to aid in maintaining the line's solidity
and reliability.
Our control lines provide reliability at up to 40,000 ft (12,192 m)
with orbital-weld-free lengths, making it easier to handle and
operate during deployment. There’s also a range of single, dual, or
triple flat-packs to choose from which you can combine with
downhole electrical cables or bumper wires.
The welded-and-plug-drawn production method we use produces a
smooth, round tube which allows for long-term metal sealing of
terminations. Furthermore, the encapsulation materials are
carefully selected to suit the well conditions so you can be sure
their longevity and reliability are secure.
We offer seamless and floating internal plug redrawn tubing supplied in the annealed condition, without orbital joint welds and in continuous length. Below are specifications of the product in terms of alloy, UNS, diameter, wall thickness and working pressure based on certain test conditions.
