ok I have a few questions about stove pipe brands. locally I have a tractor supply lowes and home depot. I can get imperial snap together stove pipe at tractor supply for cheap. lowes can also order imperial. I am looking for the welded seams. homedepot.com sells durablack which claims to be 24ga welded but after doing more research durablack now said they have a new duratech burablack welded that is 22ga. I don't want to pay twice as much and wait 2 weeks on 24ga durablack if the seam is not welded. Does anyone know if durablack single wall 24ga item #:6D24-48 is the snap together or welded?
