TEC from Meilong Tube utilizes welded stainless steel and nickel
alloy tubing in order to protect electrical and optical components
from the pressure and corrosive effects of their downhole
environment. Additionally, polymeric encapsulation comes as
complementary mechanical protection.
Moreover, Meilong Tube's wide selection of copper and fiber
components enable the production of some of the industry's most
sophisticated instrumentation cables. The company first introduced
TEC to the oil and gas sector in 2015 and has continually improved
this product, optimizing it for new generations of ever hotter and
deeper well downhole gauges and tools.
Moreover, given the almost infinite combination of components, TEC
configurations are available in splice-free custom lengths. While
the standard encapsulation size is 11 mm x 11 mm square, it is
available to meet almost any downhole requirement. Composite cables
involving various combinations of electrical and optical components
can also be provided to match any specific downhole need.
With downhole cable design experience coupled with extensive
metallurgy expertise in Meilong Tube. Our engineers invite
customers to discuss the correct tubing alloys for specific
applications.
Flatpack components can include TEC with electrical conductors,
Hydraulic control lines for controlling of downhole valves, and
Fluid injection lines for enhanced oil / gas recovery or corrosion
/ scaling inhibition.
Meilong Tube helps remove the trouble out of well completions. Our
engineers will work with you to optimize the selection of tubing
alloys and wall thicknesses, and flatpack encapsulation materials
to meet the exact requirement of your wells.
TEC is selected based on well conditions such as pressure,
temperature and corrosiveness of the well fluid. The tubing is
composed of an alloy matched to the application. It is then
longitudinally welded, eddy current tested and drawn to finished
size. Complete test data is available for every tube.

Calculations based on minimum yield strength of 120,000 psi. All
TEC tubing is oversized welded and drawn. Tubing can be custom
printed with a variety of data including part number, serial
number, sequential length and purchase order number. *The bending
radius indicated is in a static condition after final training at
the termination. All bending must be performed using a tubing
bender to ensure that the bending radius is uniform. While
deploying into or out of the well, the minimum bending radius
should be as large as possible.

This device performs two main functions: measuring temperature and
transmitting data.
Due to its precise temperature sensing, this device can provide
accurate readings of the current temperature. It can also reliably
and effectively send data across wireless networks. Thus, it makes
it an invaluable tool for various temperature-related projects.
