Combined CRA ring
A corrosion-resistant alloy insert provides high seal integrity and resistance in CO₂ and H₂S environments.
In development · open to pilot projects
High-integrity tubing connection with digital identification
The next-generation coupling combines the proven M2® sealing with RFID identification: every coupling gets a digital passport, and the tubing string gets full lifecycle traceability.
The body is a standard API coupling (8rd, EUE), structurally unchanged: full compatibility with the existing stock and processes.
A corrosion-resistant alloy insert provides high seal integrity and resistance in CO₂ and H₂S environments.
Reliable protection of the J-area and thread connection, natural make-up torque feedback — as in M2®.
No drilling of the pipe body. Records the full lifecycle of the coupling and pipe: manufacture date, make-ups, operating conditions.
A ready-made answer to the upcoming 2027–28 digital equipment passport requirements.
8–10+ cycles with no loss of seal integrity — ideal for workover stock.
Data flows through middleware into ERP, maintenance systems and corporate AI models.
The RFID tag automatically accumulates data at every operation — make-up, workover, change of operating conditions. This is what a coupling digital passport looks like:
Well 4523 · depth 2,450 m · T = 87 °C · P = 245 atm · CO₂ = 12 % · H₂S = 85 ppm · salinity 185 g/l
4 make-ups · 1,240 hours · condition: normal
Last update: 18.06.2026 14:32 · RFID: active · data in ERP
Fewer tubing replacements and workovers thanks to 8–10+ make-up cycles and corrosion protection.
Clean per-coupling data — for prediction, chemical treatment planning and procurement documentation.
Fully matches the expected digital equipment passport requirements.
Middleware plus ready connectors for ERP, maintenance systems and AI platforms.
Measurable applicability limits: temperature up to 200–250 °C, pressure up to 10,000+ psi, CO₂ partial pressure. A material selection matrix for challenging wells.
Direct reduction of tubing procurement, operation and repair costs.
M2® Smart Connect is at the development stage. We are open to cooperation with companies ready to become the first users of the technology.
