In the IGT manufacturing and repair business there are no standards and specifications and therefore the quality of work performed is strongly dependent on your vendors' inspection (written) criteria, repair and coating procedures and their execution. TEServices has developed bid/repair specifications** for most engine types in order to obtain proposals that are comparable and obtain a more consistent quality of the repairs at one or more vendors.
All of the following are currently available:
Frame 5 (MS5001) K-M N P R and New Tech
Frame 6B / 6FA
Frame 7B / 7EA / 7FA / 7FA AGP
SW 501D5-D5A / 501F
GT 11 N1 and NM
Other bid/repair specifications are in development (please let us know if one of these is of interest). Our specifications consist of one page per component of all required repair, inspection, coating, and vendor verification steps. All possible options are given at the end of the page. In the second section of our repair specifications, process requirements are outlined such as NDT, heat treatment, coating, stripping, etc.
These specifications are developed so they can be used for bid requests, with or without, the vendors having been able to inspect the components and can be used as a quality guideline. To reiterate since no industry standards for IGT components exist, the second part of these repair/bid specifications are outlined to meet the criteria for inspection (dimensional, NDT, and flow), stripping and coating, repair (weld and braze), heat treatment, and metallurgical evaluation.
TEServices can make these specifications available for end-users internal use and their (potential) repair vendors only, while TEServices maintains the copyright**.
By doing so the cost is very reasonable. As more end-users can afford these specifications, vendors are becoming familiar with them, and future updates will be made available.
Please let us know if you would like to receive more information concerning these specifications or would like to discuss them in-depth: Contact TEServices.
