Wear/Corrosion Rate on Carbon Steel Casing of Boiler Feed Water Pumps
Wear/Corrosion Rate on Carbon Steel Casing of Boiler Feed Water Pumps
(OP)
Please share the monitored data on "Wear/Corrosion Rate" in the CS casing of a BFW Pump relative to the "Quality of Feed Water" plus internal failure and casing leaks experienced due to the increasing/decreasing water quality used on the BFW pumps and preventive measures taken to solve the problem.

Are you injecting any Oxygen Scavengers in the Boiler Feed Water.
Have you considered SS or Chrome cladding inside the casing to control corrosion.
It may be much cheaper to clad the casing internals (wetted areas) with Chrome Alloys or with Stainless Steel rather than replace the entire CS Casing with a Chrome Casing.

Any idea about cost difference between a CS and Chrome casing.
I was given to understand that cost split between material and labour for large pumps is about 45% and 55% and a new chrome casing is 1.5 to 2.5 times more expensive compared to a CS casing.
