I have been trying to follow closely what has been happening with the recent steam generator tube leak evaluation for Unit 2 and Unit 3 steam generators at the San Onofre Nuclear Generating Station (SONGS).
I have been unsuccessful in getting reliable information as to the type of analysis...
For those of you that cherish old references, the attached is a beauty on plate steels.

Proper cleaing is necessary for surface nondestructive testing. I would recommend wet fluorescent magnetic particle testing (WFMT). This nondestructive examination method is one of the most sensitive to surface inspection, and this is what you need for cracking which typically...
Here is a report that was recently issued concerning the Fatal Accident at Tesoro Anacortes Refinery, located in the State of Washington.
Interesting reading;

From time to time I have seen requests on how Grade 91 material should be welded, and current industry problems with fabrication (heat treatment). The web site below contains some excellent information on welding Grade 91 material, and probably more important are actual photomicrographs of the...
Every once in a while, you come upon a treasure chest of technical information on the Internet. I believe the web site below is one of those to review for those that seek a basic understanding of materials engineering. If you scroll down to the external links, many of these links are lecture...
For those that are interested, there are two ASME B&PV Code Cases (2179-3, and 2180-2) that will be revised to reflect changes in the allowable stress values. These Code Cases pertain to the following materials 9Cr-2W and 12Cr-2W (Grade 92 and Grade 122, respectively). The changes in allowable...
During my routine search for technical information on the internet, I stumbled across this gold mine of a web site that contains archives of engineering standards by our friends at Los Alamos National Labs. The web page I book marked below has actual weld procedures that were generated for...
I had posted this in the Welding forum as well. The avesta web site below has an offer for a FREE welding manual for stainless steel. This is one of the best resource books on welding of SS I have seen.

The web site below is probably one of the best at providing a decent background on high and low cycle fatigue of materials, what effects fatigue life and an actual fatigue life calculator. This site was developed by a Professor at the U of IL (which I can claim as one of the best...
FYI:
From time to time, questions are asked regarding painting or coating of a pressure vessel or even a pressure retaining item prior to hydrotesting.
I was forwarded this interesting article that was published in Materials Evaluation, September, 1993. The article is titled " Don't Paint...
I found this file that contains a summary of forming and heat treatment equations that could be useful for technical reference;

One of the areas that I deal with are weld repairs to large high pressure, intermediate pressure and low pressure steam turbines - which can include rotating blades or stationary blades commonly called partitions or 1st stage flow nozzles in the high pressure steam turbine.
In some...

I have reviewed the recent conference proceedings and offer the following technical papers concerning the situation of your P91 induction pipe bends.
The first technical paper of interest provides an in-depth explanation of the background and creep behavior of Grade 91 steel. The...
Over the last several weeks of reading various posts, there are numerous opinions regarding the regional or national over-supply and demand for engineers.
Perhaps to reduce the supply and weed out engineers that look at engineering as an occupation (activity that occupies ones time to earn a...
