This is one of my favourite topics, since I had a large number of systems piping failures related to stress, mostly external.
One of the flange connections of the fire main systems on board a ship, couple of bolts used to break at the head frequently; more often if the ship had done some high-speed manoeuvres. Initially, we used to change the bolt and live with it, but a nagging doubt came into our minds and we did a root cause analysis. What we finally found was that, the last pipe that fitted into the system was a little oversized and had been forced into its slot using a chain pulley, thus leading to a stressed piping section. Whenever high vibrations occurred, the stress used to increase, thus resulting in the flange securing bolts at one end shearing.
I came across a nice article on the topic. Please read and be enlightened on the topic.

I have been reading a large number of articles on maintenance strategy this year. I found this one for which I have given the link below very interesting and covering the full gamut of maintenance. The schemes are applicable to all types of maintenance environments. Please take some time out to click on the link and read the article.
Enjoy and be enlightened.
Many of the modern CMMS products in the Market has the facility to upload links to media files in almost all the modules within the system. Such Multimedia files will help users in quickly referring to documents, drawings, e catalogues, SOPs, viewing maps etc. I came across a document on the subject. You could read the full document through the link given below.
Well defined removal routes for critical equipment, lists of special equipment with their storage details, emergency procedures etc will add pep to the CMMS that can give access to such documents to the concerned people whenever the need arises.
Any CMMS worth its while needs to have this facility as a quality value add. Check MPulse software for this wonderful feature.
I keep getting updates on new products used in the maintenance field through various online subscriptions.
Here is a link that shows the us of Ultrasound devices in the condition based maintenance strategy. I am not trying to sell the product, but am just trying to propagate the techniques involved. Please connect to the link given below and learn more.

Two great articles in a day.
Here is the link to another well researched article on pumps repairs with the commercial aspects explained in great detail.
Examine and break the cycle of pump repairs.
I felt that it is worth sharing. Enjoy.
Good, within tolerance, mechanical alignment between the driving motor and driven components is one of the basic health requirements.
I came across an excellent case study for which the link is given below.
Proper alignment helps one plant keep on pumping.
Please go through and be enlightened.

How many of us market our “Continuous Improvement” ideas well within the organisation?
My experience is that it is very difficult to bring about even small changes since there is a natural resistance to any change.
I came across this article on marketing your ideas to internal clients and decision makers.
Selling your ideas to help make improvements in the workplace.
Read and hone your marketing skills.
One would not come across such down to earth articles every day.
Simple examples on using the right fasteners at the right places and tightening them correctly has been covered in the article linked below:
Machinery | Improper bolting Improper bolting has the biggest impact on machine reliability and life cycle cost | Plant Services.
Using the right tools to work on fasteners is also important. The tendency to use pipe wrenches as a one tool for all fasteners lead to rounded bolt heads and joints that cannot be opened easily. Same goes for adjustable jaw pump wrenches also.
Please read and be re-trained on fasteners tightening.
In some of my earlier posts I have spoken about reliability, simple “Look, Listen, Feel” strategy in condition based maintenance strategy etc.
I came across an article in “Plant Services” web site covering a few of the areas and working towards “Operations – driven reliability.
I conducted a workshop on Reliability Centred Maintenance where I had covered the aspect of “Managing User / Client / Operator” expectations.
Please read this article following the link given below.
Electrical Power is used by all the staff members in a work force, at all levels.
To be safe, it is essential that every one understands the importance of basic electrical safety. For those who work on powered equipment, it is vital that they know more about electrical safety.
To achieve near zero electricity power related accidents in any organisation it is a must that layered, regular training and refresher sessions are conducted. Audit on how people comply to safety rules is also essential to measure the training effectiveness and attitudinal change brought about.
Here is a link to an article on the importance of training and audit on electrical safety.
