Using Non-Standard Materials for Couplings on Special Turbomachinery Applications

Abstract

Technical Brief 3: Flexible couplings are a critical component in turbo-machinery train. It is a challenge and very important for coupling designers to select suitable materials for special turbo-machinery applications. The non-standard materials addressed here are for couplings operating in environments such as: 1) Corrosion (Stress, Pitting, Hydrogen Embrittlement, Chloride, etc.) 2) Spark Resistant 3) Low Temperature 4) Titanium spacer on sensitive compressor for rotor-dynamic solutions By joint research with compressor OEMs and coupling vendors, this technical brief intends to find the best materials for the applications where working conditions or rotor dynamic concerns dictate their use.
