OCTG-Downhole

Our tubes for injection and production wells are manufactured with Corrosion Resistant Alloys, such as stainless steel and high-nickel alloys, which are ideal to withstand the harsh environment found in wells (with presence of H2S, CO2 and other corrosive chemicals). Normally these tubes are cold hardened to achieve a high resistance as well as low weight.

CRA tubes are used in designs requiring long useful lifecycles and in wells where the most extreme corrosive conditions are found:

  • High temperatures
  • High CO2 and/or H2S pressure
  • High chloride content, low pH and sulfur-free presence

 

Technical characteristics

 

Dual-phase, super-austenitic and Ni-based grades guarantee optimal performance in the specific conditions of each well and offer engineers and designers the perfect choice of materials to meet the most demanding specifications.
