Subsea
Corrosion-resistant subsea components, from ROV parts and pressure housings to buoyancy modules and connectors, for high-pressure, deep-water service.
Subsea
In
brief
Milltech machines corrosion-resistant subsea components for high-pressure, deep-water service in Norwich, UK, including ROV and AUV parts, sensor and pressure housings, buoyancy modules, flowline connectors and drilling-riser parts. We machine stainless, exotic alloys and bronze, CMM-verified with full material certification and traceability.
Overview
Subsea is where material choice and precision matter most. Components spend their service life under extreme pressure in a highly corrosive environment, so we machine subsea parts in stainless, exotic alloys and bronze, inspected by CMM and supplied with full material certification and traceability.
Components we machine
Examples include- 01 ROV & AUV parts
- 02 Subsea sensors
- 03 Pressure vessels & housings
- 04 Buoyancy modules
- 05 Flowline connectors
- 06 Drilling-riser components
