Product Description:
Meilong Tube's TEC product is significant for the oil and gas
industry since it was first launched in 2015. It is composed of
welded stainless steel and nickel alloy tubing, which allows it to
resist the strain and the corrosive nature of the downhole
environment. Additionally, the polymeric encapsulation provides
extra shielding.
The firm also offers a variety of copper and fiber components,
making it possible to produce sophisticated instrumentation cables
with unlimited combinations of components and custom lengths. Plus,
standard encapsulation sizes (11 mm x 11 mm square) are available
to meet almost any downhole requirements, and composite cables with
a mixture of optical and electrical compenents are available for
particular downhole needs.
Features:
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.
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.
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.
Technical Parameters:
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.
Mechanical Characteristics for Alloy TEC, Cold Worked are shown in
the table below:
| Diameter | Wall Thickness | Stainless 316L | Incoloy 825 | Minimum Bend Radius* |
|---|
| inches | inches | psi | psi | inches |
| 0.125 (1/8) | 0.022 | 23,882 | 25,209 | 0.75 |
| 0.250 (1/4) | 0.028 | 16,371 | 17,281 | 1.50 |
| 0.250 (1/4) | 0.035 | 19,688 | 20,781 | 1.50 |
| 0.250 (1/4) | 0.049 | 26,173 | 27,627 | 1.50 |
| 0.375 (3/8) | 0.035 | 13,783 | 14,549 | 2.25 |
| 0.375 (3/8) | 0.049 | 18,739 | 19,780 | 2.25 |
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.
Electrical Options for the TEC areprovided below in terms of the
type of electrical component and the temperature range:
| TEC Style | TEC 100 | TEC 150 | TEC 175 | TEC 200 | TEC 250 |
|---|
| Temperature Range | -10 to 100°C | -10 to 150°C | -100 to 175°C | -100 to 200°C | -100 to 250°C |
| Filler | PP | PP | FEP | FEP | PFA |
| Insulation | PP | FEP | FEP | FEP | PFA |

Applications:
Measuring Temperature and Data Transmission
Temperature and data transmission provide vital information to
ensure our daily life runs smoothly. When it comes to temperature,
if it gets too hot or too cold, it can have a major impact on the
environment and buildings. Likewise, data transmission is important
for sending instructions and data from one place to the next.
In order to measure temperature, many devices are available, such
as thermostats and thermometers. At the same time, various types of
data transmission exist for communication between computers and
other devices. Different components are used in both applications
to ensure accurate readings.
The measuring of temperature and data transmission is essential and
it is an ongoing process. However, with the advances in technology,
the process has become more efficient and accurate. As a result, it
is possible to accurately track temperature and data with greater
efficiency.
