Description

316L Stainless Steel Tubing Encapsulated Cable for Downhole Applications in Oil Wells

Tubing Encapsulated Cable (TEC)

TEC uses welded stainless steel and nickel alloy tubing to protect electrical and optical components from the pressure and corrosive effects of the downhole environment. Polymeric encapsulation provides additional mechanical protection.

A wide selection of copper and fiber components from Meilong Tube allow production of the industry’s most sophisticated instrumentation cables. Since first introducing TEC for the oil and gas industry in 2015, Meilong Tube has continually improved and optimized this product for new generations of downhole gauges and tools for increasingly hotter and deeper wells.

TEC configurations are available with an almost infinite combination of components in splice-free custom lengths.

Standard encapsulation sizes (11 mm x 11 mm square) are available to meet almost any downhole requirements.

Composite cables utilizing various combinations of electrical and optical components are available to match specific downhole needs.

Tubing Options

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.

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.
