After having to replace several sections of 24 gauge black stove pipe, 8", I sized and ordered stainlees steel piping from a local metal shop. What a difference. Not wanting to have some lightweight overpriced manufactured stuff, I went with 16 gauge welded stainless. Only one joint in the middle between two t's. No more rust, soft spots or putting my fingers through the pipe after only 2 months in service. Kudos to the local shop they do top quality world class manufacturing. Eric would know them. Anyone else gone with custom welded pipe?
