Coflexip Hose

The Apex Petroleum Services Flexible Armored Hose is generally used for 5000, 10,000 psi, and 15,000 psi applications to replace hard piping where any expansion in the work string and movement may occur.

The hoses are used to convey fluids to and from the surface test tree, to the rest of the surface test package, kill pumps, or stimulation package..

Features and Benefits

  • Suitable for service with all types of diphasic and monophasic crude oils, methanol, glycol etc. due to good corrosion resistance
  • H2S and CO2 resistant**
  • Suitable for a wide variety of applications (oil production, water injection, gas lift, stimulation etc)
  • Inner thermoplastic layer helps prevent scaling
  • Inner thermoplastic layer shows better resistance to wear than steel

* Dependent on inner liner type – consult manufacturer for limitations on chemicals
** Under certain conditions, exposure to relatively high concentrations of CO₂, inner liner can lead to damage of the inner liner

Applications

  • Onshore oil and gas well testing
  • Offshore oil and gas well testing
  • Clean-up operations
  • Crude production
  • Water injection

Operation

Numerous laboratory test programs and extensive field experience in a wide variety of applications have consistently proven that the Apex Petroleum Services flexible armored hoses are not affected by the continuous flexing with the imperative condition that the minimum bend radius is not exceeded.

The maximum velocity of flow through the flexible armored pipe should not exceed 15 m/sec. The line is resistant to bending, including frequent or constant cyclical nature of their service condition.

High crush resistance is inherent in the basic structure. Additional stainless steel outer wrap protection is provided.

The minimum bend radius is an extremely important characteristic of a Flexible armored hose.
