I'm doing a home improvement project, and I want to bury 10' of 1/2" pipe. I've been to the city and understand the codes to do this legal. In my area, buried pipe has to be either plastic coated or buried within a protective plastic pipe (typically PVC). I've got a couple of pieces of pipe that will need to be cut and threaded.
My local big box hardware store (no names mentioned) sell the coated pipe but refuse to cut threads on their expensive Rigid pipe threading machines. They claim the coated pipe clogs up their threading machines, have a nice day.
I was looking at using a ratcheting pipe threader tool, but I notice from the Rigid catalog that they recommend a different die set for coated pipe? ref: dies here and ratchet handles here. That reference shows part # 51897 for 1/2 inch "high speed for plastic coated pipe".
The whole threading of plastic coated pipe sounds odd to me. I don't understand why plain 'ol pipe threading dies don't just cut right thru the stuff. Anybody know any details here?
If I'm careful with plain 'ol dies for black iron pipe work on the coated stuff?
