Re: Fiber type pipes ( old )
If the material you're describing is what I think it is, it might be something that they called "Transite" was an asbestos-cement raceway manufactured by, I believe,
Johns Manville Co. some time ago. With all of the hub-bub around asbestos, it was discontinued. Entering "Transite" into their search engine brings up nothing. I bet they'd like to forget all about it at this point.
Be very careful if extending onto this type of raceway if it is indeed Transite. Consult proper authorities. Don't expose you or your workers to danger, and don't incur any liability!
I hope this is what you were looking for, and I hope it helps.
