Nickel Alloy Tubing Encapsulated 316L Conductor with PP Insulation
Product Description:
Flatpacks from Meilong Tube TEC provide customers with a wide
variety of configurations depending on downhole conditions. Our
products include copper components, hydraulic control and chemical
injection lines that can be color-coded and printed to facilitate
installation. Given the production process is vertically
integrated, TEC can provide fast delivery and rigorous quality
control.
The tubing is crafted from an alloy tailored to the particular
application and welded together longitudinally. It is then tested,
drawn to size and accompanied with a data sheet for each tube. The
combination of components in our products is virtually infinite and
can also be made in splice-free custom lengths. Further, standard
encapsulation sizes (11mm x 11mm square) are available to meet
various downhole needs.
We can also supply composite cables using different combinations of
electrical and optical components to suit particular applications.

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:
In the oil and gas industry, the accurate measurement of pressure
and temperature is a must for achieving optimal efficiency.
Measuring the variations in the pressure and temperature deep
inside the hole is particularly tricky, and requires
state-of-the-art technology.
Various tools are available today for measuring such parameters,
and they must be precise for obtaining the most efficient results.
