What is the difference between double and triple wall chimney pipe?

How does a double wall chimney pipe work?
The reason why you must use double-wall pipe for a clearance of 18″ or under is because it is air insulated. The outside of the double-wall pipe does not radiate heat like single-wall does. The air insulation also allows your wood stove to perform better. Double-wall pipe also produces less creosote.
Does a wood stove pipe have to go straight up?
The pipe should be as straight and short as possible, with sections properly secured. If it must have angles, limit them to one or, at the most, two sweeping 90-degree elbows or the equivalent. The horizontal portion of the pipe should rise not less than one-quarter inch to the linear foot, to insure a good draft.
