A. Dear Sir;
Sulphamic is used for Boiler Tubes Descaling.

Concentration of sulphamic acid in a solution is around 8-10% normally; but it depends on scale deposits in tubes.

A. (1)I've never heard of anyone using sulfamic acid as a reducing agent. There are some acids that are known as "reducing acids"- HCl is one of them but I'm not sure about sulfamic acid.

(2)Sulfamic acid is used by the pulp and paper industry as a descaling agent because it is a low chloride acid (for use on stainless steel) and will not precipitate sulfate salts (whereas sulfuric acid will).

thumbs up sign Hi H.N. Terry already answered that exact question. Please expand your question to request clarification of his answer, or re-word the question to involve your specific situation, or do anything other than simply repost a question which has already been answered. That's the kiss of death to a dialog :-)

Q. Hi,
I am a Senior chemist at a Gold Mine. I am tasked with finding an option for descaling an 8 km line which uses process discharge mixed with cement to paste underground mined stopes.
My question, since the line is pvc/poly and I intend to use 5% sulfamic acid; do I use an inhibitor and name me one inhibitor I can use please?

A. Hi Jacob. My specialty and the site's specialty is metal finishing, and we are not familiar with mining. Still, 5% sulfamic acid will not attack PVC or poly at all. You will find them completely resistant to the acid. Good luck.

Using sulphamic acid to clean carbon steel heat exchanger tubes

May 9, 2017

Hi everyone. I have a question regarding using sulphamic acid as a cleaner. If we have to use sulphamic acid for cleaning of tubes of synthesis heat exchanger at ammonia plant what should be the optimum parameters, e.g., concentration, temperature, etc., considering the fact that tubes of heat exchangers are made of carbon steel. Is using sulphamic acid as a cleaner in this case advisable?

A. You can use sulphamic acid at 2%

or HCl 2% with thiourea as inhibitor.
