Baker Hughes OEM-spec maintenance, in-situ PCV repair, and EVT calibration & testing for PSVs, delivered from our fully commissioned MARC workshop and dispatched to your line anywhere in Nigeria.
Based in Rivers State, our workshop gives oil, gas, and power plants across the region fast, reliable turnaround.
Every job runs inside an ISO 9001 quality management framework, so repairs stay traceable, repeatable, and safe.
Manuex Company Nigeria Limited is audited and commissioned directly by the OEM, so every repair meets genuine factory-spec standards.
Manuex Company Nigeria Limited operates the region's Masoneilan Authorized Repair Centre from our fully commissioned Onne workshop. We exist to keep control and safety valves running to factory specification, whether that means a full teardown on our bench or a field team dispatched to your line.
Multi-brand fleets, handled in our workshop or directly on your line — same standard, either way.
Complete inspection, teardown, cleaning, and rebuild of control and safety valves at our MARC facility.
Troubleshooting, component replacement, and repair of pressure control valves directly on the line — no piping teardown required.
Electronic valve testing for pressure safety valves, giving you precise calibration data under live operating conditions.
Fine-tuning of digital valve positioners, including Masoneilan SVI units, finished with industrial-grade anti-corrosive coating.
Our tooling and technicians cover flagship Baker Hughes lines plus every major third-party manufacturer in your fleet.
Steel and pressure equipment reward precision, not shortcuts. Our teams are trained directly on Baker Hughes rebuild procedures and carry that discipline into every workshop job and every field mobilization.
A transparent workflow for every valve that comes through our shop, or every field team we mobilize.
Secure logging at our Onne hub, or immediate deployment of our field team for in-situ and EVT work.
Safe cleaning and thorough analysis to identify wear or calibration drift.
Precision diagnostics and an upfront repair recommendation before any work begins.
Assembly with genuine parts, or live instrument tuning with EVT systems for safety valves.
Strict pressure testing and painting, closed out with formal test certificates to international standards.
Direct feedback from the maintenance and reliability teams we work alongside.
Manuex turned around our PSV bank faster than we expected, and the EVT certificates gave our auditors exactly what they needed.
Their in-situ team repaired a critical PCV without shutting the line down. That alone justified the contract.
Genuine OEM parts, proper documentation, and technicians who clearly know Masoneilan equipment inside out.
A pressure safety valve that drifts out of set point can fail an audit or fail the plant. Our EVT program exists to catch that drift before it becomes either.
Three field indicators our technicians check before recommending a full teardown.
Reading a set-point deviation report the way a compliance reviewer will.
