HP Reliability: A 'hundred-plus points' to improve pump reliability, Part 2

Hydrocarbon Processing Staff: Bloch, Heinz P.

Last month's column addressed items 1 ? 34. Here we present items 35 to 68. C. Lubrication issues, continued 35. On grease-lubricated couplings, verify that only approved coupling greases are use..

HP Reliability: A 'hundred-plus points' to improve pump reliability

Hydrocarbon Processing Staff: Bloch, Heinz P.

In the September 2003 issue of HP ("Letters to the Editor,") we had promised to provide reminders of "things being done" by users that consistently achieve high pump reliability. The point was made th..

Consulting Engineer: Sofronas, A.

Confined water converted to steam develops high pressures

Using creep life assessment of FCCU internals to determine operational reliability

Carmagen Engineering, Inc.: Thornton, D. R.

These guidelines can help avoid failures

HP Reliability: Consider composite materials in centrifugal pumps

Hydrocarbon Processing Staff: Bloch, Heinz P.

Fluid processing industries have embraced the use of current- generation composite materials in centrifugal pumps to increase efficiency, improve mean-time- between- repair (MTBR), and reduce repair c..

HP Reliability: Upgrade your compressor antisurge control valves

Hydrocarbon Processing Staff: Bloch, Heinz P.

Compressor “surge” is a low-flowphenomenon known to exist in “dynamic,” i.e., centrifugal and axialcompressors found in petrochemical plants, liquefied natural gas(LNG) facilities ..

Case 18: Problem-solving technique

Consulting Engineer: Sofronas, A.

An orderly procedure allows data to be organized and analyzed

Integral gas engine compressor failures and solutions

Consulting Engineer: Sofronas, A.

Here are the causes and how to remedy them

HP Reliability: Pay attention to pipe spring hangers and supports

Hydrocarbon Processing Staff: Bloch, Heinz P.

Hanger and spring support-relatedinstallation oversights are responsible for many excessive pipestress incidents. Piping-induced loads will often cause pumpcasings to deflect. Consequently, important ..

HP Reliability: Apply optimized method of stiffening pump base plates

Hydrocarbon Processing Staff: Bloch, Heinz P.

In the late 1990s, Houston-basedStay-Tru Services developed a highly effective method to minimizefield installation costs and improve reliability of pump baseplates. Its "Stay-Tru Pre-Grouted Base Pla..
