Chemjay - Do you have a closed cooling system where glycol mixtures are cooling condensate pumps or water/steam samples? I had a problem where the pH would depress boiler chemistry when a trace amount of glycol leaked into a condensate cooler as it breaks down into an organic acid. As a...
I think you have one of several issues. One is that 304 stainless and chlorine are not compatible.The higher the chlorine the more quickly the reaction. A few years back we had a level gage nearly corrode through on a bleach storage tank because it was stainless, this occured after two weeks of...
Like any engineering project, you need to spec out the end use requirements, characterize the water available, then the design is straightforward. There are a lot of good suggestions here but at the end of the day if you do not have a good specification and characterization you will be...
RO product water should always be considered corrosive however RO reject water can be either corrosive or scale-forming. The reject water contains all the ions being removed from the feed, in concentrated form. If your primary foulants are scale-forming or hardness releated you can get by with...
My experience with Bellevilles is primarily in boiler and valve applications. I think there would be little value in piping systems unless there is a unique characteristic. To simply install them to avoid installation quality concerns would speak ill of the QA/QC aspects of the job. My...
The line pigging is a good suggestion or as an alternative and since this sounds like new construction you may want to consider pulse air blows followed by recirculation with diesel through a bag filter.
I have made demisters by cutting 10 micron bag filters open and placing between two pieces of expanded metal. The piece of expnaded metal on the pipe outlet should have a reinforcing band that clamps to the pipe. I have found it is best to make the filter at least 3 pipe sizes larger than the...
I am trying to determine if there is a code requirement within B31.3 to re-test piping that had been frozen subsequent to hydrotest. I have performed visual examinations and do not see any deformations.
