Mud Motor Rotors
Stripping and re-applying the protective coating, restoring the lobe profile and repairing the rotary connections on positive-displacement motor rotors.
Industrial Sectors — 01 / Upstream, midstream & downstream
Oil & Gas
Nothing in industry is treated as harshly as a drill string. Abu Dhabi's push toward five million barrels a day keeps rigs, tubulars and wellhead equipment in near-continuous service, while sour (H₂S) reservoirs and high-pressure/high-temperature wells push metallurgy and thread integrity to their limits. Every joint that goes back in the hole has to be cut to a licensed thread form, gauged, documented and traceable.
What this sector demands
- API-licensed threading and gauging — a worn connection must be re-cut and inspected to specification, not simply re-machined
- Materials and coatings rated for sour service and HPHT downhole conditions
- Pressure-test certification and full material traceability before equipment returns to a live well
- Turnaround measured against the rig schedule, where a day of standby costs more than the repair
- UAE-based capability — ADNOC scores its suppliers on In-Country Value, so where the work is done matters commercially
How Rainbow supports it
Rainbow holds API monogram licences across five specifications that together cover the drill string and the wellhead — 5CT, 5B, 6A, 7-1 and 7-2. That means tubulars, rotary shouldered connections, drill-stem elements and wellhead parts can be threaded, gauged, repaired and certified inside one facility, alongside the machining, coating, plating and heat treatment the same components need.
Behind it
- API 5CT
- API 5B
- API 6A
- API 7-1
- API 7-2
- 6 OEM connection licences
Our specialities
What we do for Oil & Gas
Tubular & Premium Connections
API and proprietary OEM connections cut, gauged and repaired as a licensed workshop — so the joint keeps its gas-tight metal-to-metal seal and its OEM standing.
Jar Components
Drilling-jar mandrels, housings and internals manufactured or reconditioned to customer drawings and specifications.
Wellhead & Tree Parts
Repair and remanufacture of wellhead and christmas-tree equipment under our API 6A licence.
Non-Magnetic Components
Machining of non-magnetic drill-string components where survey and MWD tooling cannot tolerate a magnetic signature.

Connection licences
Licensed to cut the thread, not just the metal
A premium connection seals metal-to-metal, so its thread form is the mill's proprietary design and only a licensed, audited workshop may cut, repair or gauge it. Rainbow holds five API monogram licences and six OEM connection licences — see all of them, with licence numbers and validity.
