I've been smoking on and off for forty years, and I have never experienced a burnout, and for a long while I had only several pipes, so this isn't something that happens often. Usually it happens to those who smoke too hard, puff up a storm, which is not the best way to get flavor. Any pipe could burn out, but it is more likely with less expensive pipes where the briar isn't inspected or selected with much care ... even so it's rare. Break you pipe in gently, sip when you smoke, and burnout is unlikely.
