I would like to ask everyone: why is the fire protection piping on storage tanks made of 10# steel instead of 20# steel?#

General material requirements for fire protection pipelines: 1. Fire hydrant pipelines: galvanized steel pipes, welded steel pipes, seamless steel pipes. 2. Automatic sprinkler pipelines: galvanized steel pipes, epoxy composite steel pipes (with flame retardants) {welded steel pipes and seamless steel pipes are not allowed}. 3. Gas extinguishing systems: galvanized steel pipes, welded steel pipes, seamless steel pipes

I still don’t understand why seamless pipes made of 10# steel are used
