Siemens Turbine Repair

V94.3A4 2nd Stage Blade, gas turbine parts life extension | Siemens Turbine

MD&A’s Gas Turbine Parts Service Facility called San Antonio Service Center, is an industry leader in Siemens turbine repair. Our facility and team have leading-edge equipment and repair techniques with proven expertise on multiple frame gas turbine hot gas path and combustion components.

Our enhanced Siemens turbine new parts use proprietary advanced technology. The improved designs of the components, based on extensive repair history of these OEM products, extend the service life by minimizing oxidation, creep, and metal temperatures.

The improved designs address field distress issues including:

  • Optimized internal cooling to reduce metal temperature without increasing cooling air requirements;
  • Platform cooling to address platform thermal mechanical fatigue (TMF);
  • Modified geometry to reduce stresses that lead to cracking;
  • Blade tip cooling enhancements to improve repairability at overhaul; and refined placement of film cooling holes to address local areas of distress;
  • And refined placement of film cooling holes to address local areas of distress.

Our turnkey outage management includes Combustion, Hot Gas Path and Major Inspections. Today, we continue to expand our talent and employ many of the best minds and technical experts in the industry. Our turnkey labor specialists provide testing, inspection, maintenance, training for Siemens turbine repair in more than 20 countries worldwide.

Within our Turbine-Generator Repair facility, our high speed balance facility is one of the most modern balance facilities for power turbines in the world. Proper balancing of the turbine and generator rotors is extremely vital to ensure proper operation. The facility allows for effective testing to ensure minimal vibrations in any manufacturer’s rotor throughout testing.

This same facility also offers field machining services. Our machining capabilities include the ability to on-site or in-shop repair horizontal joints on turbine casings, rotors, and nearly any rotating or stationary Siemens turbine components.

Additionally, MD&A maintains several portable machine shops for use during customer’s plant projects. Shops are contained in portable Conex trailers for easy lifting once we deliver them to your door. Our portable machine shops come stocked with metal grinders, a drill press, lathe, and other handy tools needed to address metals work projects.

MD&A Bearings, Seals and Hydraulics Division also offers Rapid-Spares bearing exchange by assuring customers that their bearings are ready to ship, in many instances, even before an outage begins, while also offering bearing refurbishment and complete oil deflector reconditioning.
