New pipe smokers are often in an ongoing panic about burn-out. I have about ninety pipes, and I've owned a number more over forty years or more, and I have yet to have a burn-out.
What I'd worry about more, in your shoes, is over-reaming. Beginners can do a world of damage to pipes with reamers. If you'd like to eliminate that problem, you can scoop the ash out after each smoke and wipe out the bowl with an abrasive paper towel. Without cake, you'll always have a full-sized bowl and maintain a sufficient carbon layer.
