Smoke exhaust pipes are generally 15 cm and 18 cm in diameter, but now the popular ones in the market are 15 cm. It is very convenient to leave the hole small and then expand, and it is not difficult to change it to small if it is left large, but it is easy to return to the smell if the seal is not good.
