Flatpacks can include components made of copper, as well as hydraulic control and chemical injection lines. Furthermore, individual components and tubes can have colors and custom prints applied to them to make installation easier.
Meilong Tube TEC production utilizes a vertical integration model, which ensures a fast delivery, tight quality control, and the versatility to tailor configurations to specific needs. For instance, TEC selection is based on the well conditions such as pressure, temperature and corrosiveness of the well fluid. The tubing is composed of specially-matched alloy and is longitudinally welded, eddy current tested and drawn to finished size, with complete test data available for every tube.
TEC configurations are crafted with splice-free custom lengths and an almost infinite combination of components. Furthermore, standard encapsulation sizes (11mm x 11mm square) are available to meet most downhole requirements. Aside from that, a composite cable combining electrical and optical components can be created to meet more specific needs.
Encapsulation, insulation, and filler materials can all play a role in ensuring that a structure holds up to certain environmental and operational conditions. Depending on the specific needs, items such as ethylene chlorotrifluoroethylene (ECTFE), ethylene tetrafluoroethylene (ETFE), fluorinated ethylene propylene (FEP), high density polyethylene (HDPE), perfluoroalkoxy (PFA), polyamide (PA), polypropylene (PP), polyvinylidene fluoride (PVDF), and thermoplastic polyolefin (TPO/PP) may all be incorporated into a design.
The table below summarizes the trade names and minimum installation temperatures for each type of encapsulation materials:

All TEC tubing is oversized welded and drawn. It can be custom printed with a variety of data, such as part number, serial number, sequential length, and purchase order number.
Note: 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. When deploying into or out of the well, the minimum bending radius should be as large as possible.
The table below shows the various TEC styles, their temperature ranges, and their respective fillers and insulations.
TEC Style | Temperature Range | Filler | Insulation |
---|---|---|---|
TEC 100 | -10 to 100°C | PP | PP |
TEC 150 | -10 to 150°C | PP | FEP |
