Product Description:
Meilong Tube TEC - Quality Unique Products
Meilong Tube's TEC products offer a range of unique capabilities.
Flatpacks can be custom-made with copper components, hydraulic
control and chemical injection lines. Each individual piece and
tube can be colored-coded and have custom printing to make
installation easier. The company operates an entirely vertically
integrated production facility which ensures swift delivery,
thorough quality control and the widest range of available
configurations.
The choice of tubing is based on well conditions including factors
such as pressure, temperature and corrosiveness. It is produced
using materials best suited to the application, followed by
longitudinal welding, eddy current testing and then drawn to
finished size. Comprehensive test data is provided for every tube.
By opting for TEC, customers can benefit from the almost limitless
selection of components in custom lengths without the need for
splicing. In addition, Meilong Tube now provides standard
encapsulation sizes of 11 mm x 11 mm square to meet the most
exacting requirements. Lastly, composite cables incorporating
various combinations of electrical and optical components can be
supplied to match any special downhole requirements.

Mechanical Characteristics for Alloy TEC, Cold Worked
The table below shows the mechanical characteristics for alloy TEC
when cold worked:
| Diameter | Wall Thickness | Stainless 316L (psi) | Incoloy 825 (psi) | Minimum Bend Radius* (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 |
These calculations are based on the minimum yield strength of
120,000 psi. All TEC tubing is oversized welded and drawn and can
be custom printed with a variety of data including part number,
serial number, sequential length and purchase order number.
The indicated bending radius is in 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. When
deploying the tubing into or out of the well, the minimum bending
radius should be as large as possible.
Electrical Components
The table below shows the electrical components of the TEC styles:
| 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:
The oil and gas industry presents several specific challenges when
it comes to pressure and temperature monitoring down hole. Taking
measurements in such a grueling and hostile environment can be
difficult, as various conditions, such as high temperatures,
pressure, corrosive gases and liquid streams, can interfere with
the performance of any instrument deployed.
These conditions can affect the accuracy of the results from any
temperature or pressure sensing instrument. Numerous robust
technologies have been developed to enable the successful operation
of sensing applications in the oil and gas industry, where extreme
conditions and hostile environments are commonplace.
