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.

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.
