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.
