We put Duplex 2205 and Stainless Steel 316L head-to-head to see which is best for
eSlicklineTM
An innovative 0.160″ / 4mm diameter 200°C real-time slickline cable.
eSlicklineTM – 4mm Downhole Slickline Cable
4mm (0.160”) Downhole Instrumentation Cable (TEC) is the perfect combination of strength and flexibility. The 0.030” stainless steel wall thickness is similar to 0.125” slickline cables with a real-time advantage. Proven compatible with all major eline telemetry systems including Warrior, SLB, and Sondex. Can connect to any existing eline tool with 600V or less voltage rating with custom go rope socket connector.

Metal Jacket:
Material
Stainless Steel 316L or Incoloy 825
Most of the cables we ship are made of high quality Stainless Steel 316L. This material provides both great strength, and corrosion resistance. If however your particular well has an exceptionally hostile downhole environment, you may want to consider Incoloy 825. This metal jacket material provides extra protection against sulfuric and phosphoric acids, oxidizing acids, putting, stress corrosion cracking, inter-angular corrosion, and damage caused by high concentrations of downhole CO2.
