Preventive maintenance plans for rotating machinery are well established and published.

But do we really require similar plans for stationary equipment e.g. heat exchangers, furnaces, reactors, vessels etc. Most are inspected on every turnaround i.e., every two years.

What are the best practices around that you people use?

Should stationary equipment be a part of PMP or on required basis maintenance?

I recommend maintenance plans for all your equipment that you perform maintenance on. It is the best way to guarantee standardized work, that is to say you know the work should get performed the same way every time you do it.

We even started writing CM work plans on certain equipment to aid system owners and the technicians on known possible breakdowns. It helped drive consistency and overall reliability.

If you have submersed electric heat exchangers I’ve found a megger test to be extremely valuable to judge element condition. Having work plans allows you to record data in the CMMS if you like for later reference.

If you’re ever inspected any a regulating agency it’s so valuable to be able to point to your CMMS system for your work history and maintenance strategy.

Hi Yahoo,

Majority of those are covered under RBI(Risk based Inspection)Policy. that will set the Inspection/Maintenance frequency guidelines based on condition as found ,rather than fixed time maintenance

I agree with Wally, you need a maintenance plan for ALL equipment.
Parts of the equipment which are pressure containing or require structural integrity can be best analyzed using RBI (KJAP, please note, RBI covers only these areas).
Other parts tend to have age-related failures: wear, creep, corrosion, or fatigue related. These are best done on a fixed time basis, usually beginning with an inspection.
Inspection IS a maintenance activity. The follow-up repairs are also maintenance activities.
