Service & Maintenance

Plants in operation face a different problem from new installations: the work has to be completed within a given shutdown window, on equipment that is already in service.

Simgetek carries out maintenance, repair and revamp work on this basis, deploying the same engineering, fabrication and machining resources it uses to build new equipment.

Scope of Service

Condition assessment and dimensional survey of existing equipment
Reverse engineering and preparation of drawings where original documentation is not available
Dismantling, repair and reassembly of equipment
Replacement of worn or damaged sections
Spare part fabrication
Machining and balancing of rotating parts
On-site welding, weld inspection and non-destructive testing
Support during testing, cold and hot commissioning and return to service
Repairs and alterations to ASME-certified equipment under the National Board R stamp

Revamp and Modernisation

Revamp scopes often go beyond repair, covering capacity increases, the replacement of complete equipment sections and the fabrication of new units with up-to-date materials:

Replacement of heat exchangers and pressure equipment in operating process plants
Revamp of storage tanks, including dismantling and re-fabrication
Rehabilitation of equipment such as rotary kilns, including shell replacement, associated welding and NDT
Revamp of fired equipment such as water bath heaters, including fireboxes and tube bundles
Capacity increase work in existing production plants

Project Experience

Hydro turbine maintenance and repair; impeller, head cover, runner, guide vanes, draft tube, wear ring and gland work, together with balancing, testing and commissioning
Rotary kiln rehabilitation; tyre and shell replacement, associated welding and NDT, followed by cold and hot commissioning
Heat exchanger revamp at a fertiliser complex; fabrication, dismantling and re-erection, with site testing
Revamp of an underground fuel-oil storage tank; dismantling, pre-fabrication and re-erection
Revamp of indirect water bath heater systems; fabricated in one piece in our own facilities and tested before shipment

How We Work

Shutdown duration is treated as the governing constraint; preparation and pre-fabrication are completed in advance
Replacement parts are fabricated and, where possible, trial-assembled before the shutdown begins
Where dismantling is not practical, machining is done on site with portable equipment
All repair work is documented to the same standard as new fabrication
