FEP Encapsulated Incoloy 825 Hydraulic Control Line Flatpack

April 11, 2024 at 13:16 PM EDT

Short Description:

Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.

Typical Tubing Size

Outside diameter of control lines is mainly 1/4’’ (6.35mm).

Wall thicknesses: 0.035’’ (0.89mm), 0.049’’ (1.24mm), 0.065’’ (1.65mm)

Control line tubing is available in lengths from 400 feet (122 meters) to 32,808 feet (10,000 meters). No orbitally butt welds.

Other specifications (1/8’’ to 3/4’’) are available on request.
