Shaft Machining

Our Field Machining Division was dispatched to repair an inboard fan shaft for a Utility customer in the Midwest.  We mobilized a total of 4 specialty field machining personnel, and began the process of machining the inboard fan shaft which had severe shaft damage and hard spots.  We cleaned up 100% of the shaft, had […]

G2 Main Control Valves

  We recently overhauled the main control valves for a GE G2 Steam Turbine rated approximately 550MWs.  In this instance, we removed the control valves and shipped them to our Gainesville, Georgia Steam Valve Repair facility for disassembly, cleaning, and inspection.  If any of the components are in need of repair we can make them […]

Turbine Wheel Manufacture

We recently manufactured a new turbine wheel at our Gainesville, Georgia component reverse engineering and manufacturing facility.  The team does an amazing job at manufacturing components to very strict tolerances, with the final product being to specification and delivered to the customer in a timely manner. Here is some feedback we received this week from […]

G-3 Steam Turbine Major Inspection

We recently executed a Major Inspection on a GE G-3 Steam Turbine rated over 750 MW for a major Utility company in the U.S.  This type of project is long and detail-oriented. The attention to safety each and every day must be at the forefront of every project, but especially one of this magnitude. There […]

Turbine Valve Seat Replacement

We recently completed a Control Valve Seat Replacement on a GE Steam Turbine.  In some cases the existing seat can be pulled, in the case shown below it was required to machine out the previous seat.  We also machined out the existing pins, manufactured new pins and seat, and installed the new components during the […]

Thermal Imaging of the Power Island

Thermography is a condition-based maintenance technique that is used to monitor the condition of plant machinery, structures, systems, and media (i.e. steam, oil, water, etc.).  By detecting thermal anomalies (i.e. areas that are hotter or colder than they should be), an experienced Thermal Imaging Specialist can locate and define incipient problems within the Power System.  […]

Has your steam turbine outage been postponed?

Many turbine outages this spring have been postponed, and we have a solution to provide peace of mind and mitigate the risk of postponed maintenance. Your turbine may now be at the point where damage to the internal components could accelerate during this extra runtime. Or perhaps the turbine is operating optimally and the postponed […]

Steam Turbine Valve Inspections

We recently performed work for a U.S. utility on one of their Main Stop Valves for a GE Steam Turbine.  We can perform valve inspections on-site or in our dedicated steam turbine valve facility in Gainesville, Georgia.  If the valves are inspected at our Gainesville facility we have the ability to make any necessary repairs, […]

Collector Ring Machining

  During any turbine generator outage season we often receive an influx of calls to perform collector ring machining on various makes and models of generators.  It is critical to maintain as much brush to collector ring contact as possible, and machining the rings can make sure the surface is free from defects that may […]

Gas Turbine Compressor Inspections

We recently completed the inspection of a Westinghouse Combustion Turbine Compressor Section.  This inspection can be performed standalone, or is typically performed as part of a Major Inspection.  It is imperative that the compressor section is free from defects and has proper clearances to allow air to flow toward the combustion section as smoothly as […]
