Industrial sectors

Every sector runs on components. We keep them running.

Rainbow repairs, reconditions and manufactures mechanical components for the industries that cannot afford to stop. Choose your sector to see what it demands and what we bring to it.

Eight sectors

Pick your industry

Each sector has its own page: the engineering reality of that industry, the requirements it places on a machine shop, the specialities we bring and the licences behind them.

Connection licences

Licensed to cut the thread, not just the metal

A tubular connection is not an ordinary thread. Premium connections seal metal-to-metal, giving gas-tight integrity without relying on thread compound — which is what makes them viable in sour and high-pressure/high-temperature wells. Because the thread form is the OEM's proprietary design, it can only be cut, repaired and gauged by a workshop the OEM has licensed and audited. That licence is what allows a repaired joint to go back in the hole with its original standing intact.

API monogram licences

The American Petroleum Institute licenses our shop against five specifications covering tubulars, threading and wellhead equipment — the scope that lets us certify, not just machine.
