Service & Delivery

From break to repair.

Our integrated approach to on-site machining, controlled bolting, and digital flange integrity management guarantees projects are delivered safely and correctly the first time. Supported by calibrated torque and hydraulic tensioning systems, we deliver immediate precision through specialist flange facing, milling, and drilling.

To ensure total transparency, we standardise our procedures to industry best practices and digitally track every stage of the project. At the core of this is our iBolt software platform. From the initial break and inspection through to final assembly, tightening, and testing, iBolt captures the entire joint lifecycle.

This fully auditable workflow ensures joints are leak-free and compliant, directly supporting safe start-ups and reliable ongoing operations. By providing clear, long-term visibility into joint history, our process streamlines maintenance, reduces overall lifecycle costs, and delivers total asset integrity without compromising on speed or precision.
