As an infrequent pipe smoker, this was one of the things that kept happening to me and causing me to shy away from pipes.

Solved the problem for the most part for me by varying the angle of the pipe in my mouth during the smoke and trying not to overheat it by drawing to hard or frequently.

My thought was the small orifice of the stem was concentrating the smoke on a small area of my tongue on the draw vs the larger diameter that the head of a cigar produces and the overheat my technique was producing compounded the effect.

Dunno if it was the slowing down or the movement, but it seems to help me.
