HP Engineering Case Histories: Case 69: Heat-up rate and rubs on a steam turbine
This column has suggested using simple analytical models to troubleshoot equipment. However, in some cases, a more detailed solution may be required. The following case histories examine the heat up o..
HP Reliability: Avoid unnecessary developments
Innovative thinking is appropriate in the hydrocarbon processing industry, and tremendous forward movement has occurred over the past 30 years. Innovation is to be commended, unless we invent or disco..

‘Best available technology’ is a must for backup systems
HP Reliability: How do you size expansion chambers (assuming it is needed)
Expansion chambers (Fig. 1) are designed to restrict pressure increase in closed volumes. From basic physics, we, of course, know that the pressure in a closed volume increases as temperature goes up...

HP Reliability: Consider ‘water washing’ for steam turbines
Occasions may arise when deposits form on the internal parts of steam turbines. The accumulation of these deposits may be indicated by a gradual increase in stage pressures over time with no evidence ..
