Selection of ammonium sulfate dust removal pipelines? ?
Thread Content
The outlet pipe for water bath dust removal in the sulfuric acid AN section of our plant is severely corroded, and we are planning to replace it. It was originally made of 2 mm thick stainless steel; do any of you know of other materials that could be used as a substitute? The original pipe has an outer diameter of 420 mm, and the connection method is slip-on flange connection. :)Thank you
What is the temperature? Is it a coking plant? How long is the service life of original stainless steel?
Please specify the process conditions: temperature, pressure, process medium, etc.?
It is best to provide the temperature. Anti-corrosion solutions include roll-coating PO and PE on the inner wall of pipes, steel-lined PTFE pipes, and PTFE spraying on the inner wall of pipes. Prices and performance vary. It depends on the pipe size and temperature, as well as which anti-corrosion solution is most suitable in each case. It is recommended to chat privately.
