Cowboy, I read this thread when originally posted. I'm surprised you haven't sold the pipe. It is high as a cat's back in price in this neck of the woods.
Sucker pipe? I spent most of my life as an oil field welder and never heard that. Sucker rod, yes. Tubing, yes. Guess it's an area thing.
As far as welding the plastic lined stuff, it's like welding galvanized, do it outside and stay up wind and you will be OK. Stick your head in the smoke for any length of time and you'll regret it.
