Product Description:

Meilong Tube has introduced TEC for the oil and gas industry since 2015. It is a welded stainless steel and nickel alloy tubing specially crafted to protect electrical and optical components from the pressure and corrosive effects found in downhole environment. To further strengthen the mechanical protection, polymeric encapsulation is also employed.

There is a wide selection of copper and fiber components from Meilong Tube. These allow users to construct industry’s most sophisticated instrumentation cables, and generations of downhole gauges and tools for even hotter and deeper wells, all of which are optimized for newest technologies.

TEC is highly customizable in both components and length desired for a specific use. Standard encapsulation sizes (11 mm x 11 mm square) are available to meet almost any downhole requirements. Furthermore, there are composite cables incorporating various combinations of electrical and optical components, enabling users to meet the specific demands for downhole needs.



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.


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.

The table below provides the mechanical characteristics for alloy TEC, cold worked:

Diameter Wall Thickness Stainless 316L Minimum Collapse Incoloy 825 Minimum Collapse 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

The calculations are based on the minimum yield strength of 120,000 psi. All TEC tubing is oversized welded and drawn and it can be customized with a variety of data including part number, serial number, sequential length and purchase order number. It is important to note that the bending radius indicated is only in a static condition after final training at the termination while deploying it into or out of the well, the minimum bending radius should be as large as possible.

The following table outlines the electrical conducting capabilities for TEC tubes:

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

The following table shows the maximum electrical conductor resistance at room temperature, 20 °C (68 °F):

Temperature is an important factor in survival and optimal performance, and since ancient times, technology and methods have been used to measure it. Recent advancements in thermocouples and thermistors have enabled more precise temperature measurement, and the development of different data transmission technologies has made it easier to accurately and efficiently detect and log temperature data.

Thermocouples are two-wire electrical circuits consisting of two dissimilar metals that develop a small electrical voltage when heated or cooled. This voltage can be used to measure the difference in temperature that the two metals experience. Thermistors are sample resistors with a resistance that changes when exposed to different temperatures. The change in resistance can be used to measure temperature.

The development of various data transmission technologies, such as Bluetooth, Radio Frequency (RF), and Universal Serial Bus (USB), has greatly improved the ability to collect and log temperature data. With the help of smartphones, tablets, or computers, any temperature data can be accurately captured and recorded, making it easier to identify temperature trends and potential problems.
