Any thoughts or experience in system life expectancy for dry sprinkler systems with galvanized versus black steel pipe, and compressed air versus nitrogen?
Our firm (MEP/FP consultants) typically recommends nitrogen and galvanized pipe for dry sprinkler systems, and we often get the value engineer requests to accepts compressed air and/or black steel.
Any studies or data that support your experience? Approximate cost savings you might expect from each?
Thanks in advance!
