question about galvanized plastic pipe


I have galvanized plastic pipe, it's gray, in my house. I wanted to add a new line to a second hot water heater. I cut the line were I need to sweat in the line to the new hot water heater but every time I apply heat, the line starts to melt or catch fire. What am I doing wrong?
Thanks and this is a great forum.

we join 2" plastic water mains with a buttweld.
basicly melt the two ends till they look like fish lips then mush together; requires special tools.

I went to a local hardware store and told the plumbing slaesman about the buttweld problems I have. He sold me a metal tee and some clamps to put it all back together.
Thanks for the help.
