pipe Strain| Precision Shaft Alignment| Pipe Stress

By Stan Riddle on November 9, 2020

I recently had the pleasure of teaching an alignment class for a Midwest company involved in pipe fabrication and installation.  Their primary concern wasn’t so much in precision shaft alignment, but in being able to measure the effect pipe strain has on alignment.  Before I arrived, they had told me they had fabricated a rig […]

Not only do we write blog articles at VibrAlign, we also read them. Nearly every training session I conduct, pipe strain as a source of alignment frustration, comes up. I recently came across an excellent blog written by Ricky Smith CRL CMRP CMRT that I would like to share. There is some really good information […]

VibrAlign has introduced the Fixturlaser Runout Probe, an accessory device for the Fixturlaser NXA Professional.  I (as a jaded, grizzled old millwright-but a good “company man”) was outwardly excited.  But inside, I thought, what’s the big deal?  It’s an electronic dial indicator. That’s what I thought – until I took it for a test drive!  […]

Have you ever struggled with a precision shaft alignment, even though you did everything right? (Preformed the pre-alignment steps, controlled backlash, etc., etc.) So, what was different? Maybe it was pipe strain. An alignment check of a new installation of a 40 HP, 3600 RPM motor/pump  revealed the vertical angular misalignment was 3.2 times the […]

Alignment tolerances| pipe Strain| "shaft alignment"

By Michael Keohane on July 7, 2014

Pipe strain is a relatively common problem seen in pump installations. It is a cause of premature bearing and seal failure. Here is a link to an excellent article from Pumps and Systems magazine that discusses the detrimental effects of pump strain. http://www.pump-zone.com/topics/seals/how-do-plant-pipe-strain-problems-affect-my-pumping-systems You can easily measure the effects of pipe strain using dial indicators […]
