Steam Turbine Pipe Strain Case Study
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing foot movement for pipe strain verification. The turbine’s bearing housings and process casing are independent of each other. With this type of arrangement, pipe strain would have to be at the extreme to see movement at the coupling. Instead, the casing foot movement should have been monitored. This case study will present the initial as-built conditions vs. the after 6 months of service pipe strain findings and resolution.
