About Pressure Services

Euro Mechanical delivers pipeline intervention capabilities that enable modification, isolation, repair, and integrity restoration of live pressurised systems without shutdown. Covering hot tapping and line stopping, in service welding, pipe freezing, leak sealing, wellhead gate valve milling, and composite repair solutions, the service allows operators to maintain continuous production while executing critical maintenance, repair, and intervention activities across pipelines, process systems, and associated assets.

Operations are governed by internationally recognised standards including ASME B31.3, B31.4, B31.8, ASME Section VIII, API 1104, and API 2201 supported by PRCI validated in service welding assessment, detailed engineering review, and project specific risk analysis. Interventions are engineered around live operating conditions such as pressure, temperature, media, pipe size, and material integrity, ensuring each solution is technically validated, controlled, and safe to execute without compromising system integrity.

With in house design and manufacturing of intervention tooling and fittings, a large multi disciplinary field workforce, and expanded in country capability following the 2025 acquisition of Wellube, Euro Mechanical provides a single accountable partner for live plant and pipeline intervention. This integrated approach enables rapid mobilisation for planned and emergency scopes, combining engineering depth, specialised equipment, and certified execution teams to deliver safe, reliable outcomes while minimising downtime and production loss.
