Mechanical works — static equipment & pumps.

We work on critical assets, meaning equipment whose shutdown stops a line or the whole plant. In this context mistakes do not show up straight away: they show up months later as a leak, abnormal vibration or a crack, when nobody links the cause to the effect any more.

What we do.

Our mechanical job does not end with reassembly: it ends with the documentation that proves how it was reassembled.

There is a practical reason for this. On an operating plant, the next person to open that vessel or that pump will not necessarily be the one who closed it, and often not even from the same company. If they find no recorded bolt torques, no measured alignment values, no filler metal traceability and no acceptance criteria applied, they have to start from scratch, or proceed by estimate, which is worse.

That is why we treat every mechanical activity as part of a closed documentation system: qualified procedure before starting, parameters controlled during execution, records at the end.

Welding is where this approach matters most. We cover SMAW, GTAW, GMAW, FCAW and SAW on carbon and low-alloy steels, austenitic stainless steels, duplex and super duplex, nickel alloys and overlay. Full details are on the Technical Capabilities page.

Scope of work.

Static equipment

• Erection and installation of pressure vessels, columns and reactors
• Piping erection: edge preparation, fit-up to isometrics, welding and inspection
• Opening, inspection and box-up of shell & tube exchangers and air coolers, including tube inspection and plugging
• Storage tank work: bottom, shell courses, welds and geometric checks
• Replacement of piping sections on boilers, furnaces and process circuits
• Controlled bolting: torque or tension tightening, with sequence and values recorded
• Post-weld heat treatment (PWHT): cycle definition, thermocouple placement, chart validation
• Overhaul and testing of safety, control and isolation valves
• Hydrostatic and pneumatic pressure tests, witnessed and recorded

Rotating equipment: centrifugal and positive-displacement pumps

Our rotating scope is stated precisely: centrifugal and positive-displacement pumps. We prefer a short, true list to a long, generic one, because on this kind of equipment the difference between doing the job and knowing what you are talking about shows on the first intervention.

• Installation on baseplate, grouting check and flatness verification
• Laser pump-motor alignment, with soft foot check and correction
• Run-out check and clearance verification against manufacturer tolerances
• Mechanical seal and bearing replacement
• Complete overhaul and reassembly with measured values recorded
• First start-up functional checks and recording of operating parameters

Applicable standards.

The applicable code is agreed at kick-off and written into the Inspection & Test Plan. From then on it is the yardstick for accepting or rejecting every single activity.
