Was hoping to get some input from more experienced people. We are doing some tests of drilling into a pipe (through the pipe) and then reaming it to allow for a solid metal plug to seal the pipe.
We are finding the reaming machine has jammed, and broken. The material we are cutting is regular pipe A106 Carbon steel, but the temperature of the pipe is 750F.
Are there some guidelines for maximum metal temperature for drilling/milling/reaming practice? What kinds of things (if any) are you concerned with having your base metal at that temperature?
