Inspection Frequency of HP Loop of Urea plant
Inspection Frequency of HP Loop of Urea plant
(OP)
We are operating a Urea plant built on Stamicarbon technology. The High pressure synthesis loop (consisting of Reactor and stripper and HP Carbamate condensers) is made of Safurex material. We had inspected it with Stamicarbon experts in 2011 and they advised to keep the next inspection after 6 years period (2017). However our operation engineers are now insisting that we should not wait until 2017 and inspect it in 2015 shutdown.
Has somebody any idea about the inspection frequency of HP Urea equipment.

Unless something fails after the shut-down and before the 2017 inspection and your name is on the decision to not do an inspection during the shut-down.
Then it's your ass.
Which is more valuable to you?

If you had it inspected by Stamicarbon inspection team before and they can provide you these details it should be a good start.
The general industrial practice is to inspect in 3~4 years. Deciding factor will always be the corrosion rate and previous inspection history.
