Assessing Useful Life Of Turbomachinery Components.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The last four of five decades have seen considerable advancements in the life assessment methods of mechanical components. These methods have been shown to be equally suitable for new as well as used components and even ...
Experiences And Applications Of API 617 Full Stability Analysis (Level-II) On Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2005)
To cover the remaining operation life of an offshore platform, it was necessary to go from a single stage compressor to a two-stage compressor. The design of the new two-stage compressor required two different impeller ...
Rotordynamic Design Of Centrifugal Compressors In Accordance With The New APIStability Specifications.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The American Petroleum Institute (API) has recently implemented new rotordynamic stability specifications for centrifugal compressors. The specifications consist of a Level I analysis that approximates the destabilizing ...
Repair Technologies Of Mechanical Drive Steam Turbines For Catastrophic Damage.
(Texas A&M University. Turbomachinery Laboratories, 2005)
Mechanical drive steam turbines play an important role as core equipment in petrochemical plants, and these turbines are protected for safe operation by an antioverspeed trip device, as well as other monitoring and protection ...
Application Of A Crack-Closure Model For Turbine Life Assessment.
(Texas A&M University. Turbomachinery Laboratories, 2005)
This paper describes the application of a fracture mechanics-based procedure for life estimation that allows complex load cycle effects to be included. The procedure is based on technology developed by the aerospace industry, ...
Hermetically Sealed Oil-Free Turbocompressor Technology.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The reciprocating compressor and the traditional centrifugal compressor have been the workhorses of the natural gas industry. However, new demands placed on gas distribution infrastructure by spot market activity necessitates ...
Turbine Failure And Reconstruction.
(Texas A&M University. Turbomachinery Laboratories, 2005)
This paper is an extended case history of a turbine catastrophic failure due to stress corrosion and the reconstruction of the turbine, compressor, gearbox, and the drive motor after a fire. Wheel stresses and the design ...
Axial Alignment And Thermal Growth Effects On Turbomachinery Trains With Double-Helical Gearing.
(Texas A&M University. Turbomachinery Laboratories, 2005)
Turbomachinery shafting and casings typically experience axial growth during thermal transients occurring at startup, shutdown, and changes of load. This growth does not usually present difficulties during operation. ...
Hydraulic Shop Performance Testing Of Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The purpose of this tutorial is to familiarize the rotating equipment engineer with in-shop hydraulic performance testing methods. The tutorial discusses the theory of similarity testing, the assumption, and inherent errors. ...
Gas Turbine Performance.
(Texas A&M University. Turbomachinery Laboratories, 2005)
Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by ...
