HP Reliability: TAMU Turbo and Pump symposiums still leading
Beginning in 1971, the Turbomachinery Laboratory of Texas A&M University (TAMU) organized the first of now 41 consecutive annual turbomachinery symposiums, now known as the TAMU Turbo. In 1984, Texas ..
HP Reliability: Upgrade the design of vertical, multistage centrifugal pumps in low-temperature services
The overall mechanical design of most API-style vertical-column pumps (Fig. 1) comes close to meeting the expectations of modern pump users. Such pumps are often equipped with self oil-lubricated bear..
HP Reliability: Closed-oil-mist systems and maintenance cost avoidance
A recent Hydrocarbon Processing (HP) article conveyed an industry finding that dates back several decades: Oil mist successfully lubricates operating machinery, protects and preserves standby equipmen..
HP Engineering Case Histories: Case 70: Twenty rules for troubleshooting
In previous Engineering Case History columns, I have discussed checklists and their value in avoiding errors during startups. While the rules cannot replace common sense or a logical and methodical ap..
HP Reliability: Consider best-of-class lubrication practices
Last month’s column explained that all hydrocarbon processing (HP) facilities use machinery, and these machines require lubrication. Periodically auditing one’s lubrication practices is part..
HP Impact: The modern world of steel
The World Steel Association recently published the 2012 edition of “World Steel in Figures.” This study provides essential facts and statistics about the global steel industry, including inf..
HP Reliability: Rethink your auditing of lubrication practices
All hydrocarbon processing industry (HPI) facilities use machinery, and every one of these machines requires lubrication of some type. Modern, profitability-minded plants thoughtfully manage their lub..
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..
