Types of Stove Pipes
Stove pipe is used to connects a wood-burning stove to a chimney system. The different types of stove pipe vary primarily on the basis of metal thickness, seam and number of walls. Stove pipe also varies in internal flue diameter. Does this Spark an idea?
-
Single-walled stove pipe.
-
As its name suggests, single-walled stove pipe has one layer of steel wall. Single-wall pipe must have a minimum 18-inch clearance from combustibles. Single-walled pipes vary in thickness of their steel. Most stove pipe steel is between 22- to 30-gauge steel, with the smaller numbers being thicker steel. Another variation is the type of seam. Less expensive pipe has snap-together style seams and is sold in stacks of flattened sheets. More expensive pipe has welded seams.
Double-wall stove pipe.
-
Double-walled stove pipe is constructed with two closely-spaced steel walls. The air space between steel walls provides additional heat shielding. This allows narrower clearance to combustibles compared to single-walled pipe. Depending on the application, double-walled pipe clearances range from 6 to 8 inches.
-
Flue diameter.
-
The flue is the internal space that smoke and exhaust gasses pass through. Stove pipe is generally available in whole-inch sizes from 5 to 12 inches. Size is specific to the stove the pipe will vent.
