Restoring a traditional wood stove pipe kit usually means having to replace their pipes. The diameter of a chimney is an important piece of information to have when buying new pipe pieces. You will find the diameter through basic geometry to avoid having to review tubes for any markings. Quickly calculating the diameter of the tube can allow you more time to spend on restoration.
Wrap the tape measure around Stove pipe on the crimp to measure its circumference. The crimp is the end portion of the stove tube that has vertical creases that allow the pipes to interconnect. As an example, we say that the Stovepipe circumference is 15 11/16 inches. Divide the numerator by the fraction of its denominator to get its decimal counterpart, and then add that number to whole inches obtained in circumferential measure. This will convert the measurement into decimal form. In our example, divide 11 by 16 results in 0.6875, so we add, 6875-15 for a total circumference of 15.6875.
Round this number to include only two decimals. In our example, 15.6875 would be rounded to 15.69. Divide the circumference of the numeric constant π with your counter. The constant π has an approximate value of 3.14. Using examples you would divide 15.69 by π and get a result of 4.99 inches. This number is the diameter of wood stove pipe.
Tips and warnings
If you cannot find a cooker tube with the exact diameter, order one that is slightly larger. It is easier to close the crimp stove tube longer than to open it wider.
