Stresses in Piping systems

Hi all,

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.

Linking Media Files in CMMS Modules

Hi all,

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.

Combine vibration monitoring and ultrasound for more cost-effective predictive maintenance

Hi all,

predictive maintenance is one area that needs no introduction. Combination of techniques and tools available currently makes this a very competitive process. With this process, we can determine when to do any maintenance. Yes, preventive maintenance processes also will be followed, but instead of doing them mechanically as per a time schedule, it gets done when it is required to be done.

In most cases, the buffer time provided for time based preventive maintenance schedules is too much and we end up over-maintaining the equipment causing the following:

  • Doing maintenance on fully functional, healthy and operational equipment
  • Replacing the mandatory spares and consumables every time we do maintenance
  • Creating a condition where the equipment could fail due to man-made mistakes during assembly of equipment, post-maintenance.

I came across a wonderful article covering predictive maintenance using a combination of techniques and tools. The link is given below.

Predictive Maintenance: Combine vibration monitoring and ultrasound for more cost-effective predictive maintenance.

Please take some time to look up the link, read and be enlightened.

Take inventory of your maintenance costs

Hi all,

Inventory; the timely availability of spares parts, common supply items and tools is essential to both preventive and reactive maintenance. Preventive maintenance allows for some advance planning, but break down does not give us any buffer time.

An ABC analysis of inventory holding will indicate that the bulk of the material stored are from the A category – low-cost, frequently used, bulk requirement type. The B category items are also fairly large in number, but the C category would be less in numbers, but high in cost.

I came across an article on Inventory control and CMMS to which the link is given below:

Contracted MRO services: Take inventory of your maintenance costs.

A good CMMS will have an inventory module that allows to do analysis of inventory usage pattern, inventory carrying costs, inventory management etc.

Please read the article and be enlightened.
