Key Features of Encapsulated Control Lines

What Is an Encapsulated Control Line?

An encapsulated control line is a metal tube (typically stainless steel or alloy) encased in a protective polymer jacket. This encapsulation shields the tubing from mechanical damage, corrosion, and extreme temperatures, making it ideal for harsh downhole and subsea environments.

Main Features

- High Pressure Resistance: Designed to withstand pressures exceeding 15,000 psi, ensuring reliable performance in deep and challenging wells.

- Corrosion Protection: Encapsulation materials like FEP, PVC, Santoprene, and Nylon provide excellent chemical resistance, safeguarding the metal tubing from corrosive fluids and gases.

- Thermal Stability: Operates reliably at temperatures up to 200°C, maintaining integrity and performance in high-temperature environments.

- Dimensional Precision: Available in outer diameters from 1/8″ to 1/2″, with wall thicknesses from 0.02″ to 0.083″, allowing for precise engineering and installation.

- Customizable Shapes: Offered in round, square, and flatpack configurations to suit various installation requirements and space constraints.

Quality Standards

All EMHK encapsulated control lines are tested by leading third-party organizations and meet or exceed ASTM A269 and other international standards. This commitment to quality ensures that every product delivered is safe, reliable, and fit for purpose.
