Installation of black pipe

The lower temperature condensation will drip creosote down the pipe. If the male end is incorrectly pointing upwards, liquid formed by condensation will always travel down the path of least resistance, and will eventually drip outside of the pipe just like in this picture. By having the male end pointing down, any drips will fall into the female end of the pipe below and back into the stove to be burned.

Now, you may look at your stove pipe setup and say, "The male ends of my pipes are pointing up and I don't have any problems and it's been working like that for years". If it hasn't happened to leak "yet", it's only a matter of time until it does. Changing the pipe configuration will take the "yet" out of the equation and prevent it from happening entirely.

Gas Pipe Protection from Corrosion Protect metallic gas pipe in an approved manner if exposed to corrosion. Use factory-applied protective coatings on metallic gas piping and fittings.

Use insulating couplings or fittings when joining dissimilar metals underground. How long do underground gas pipes last? Can you bury galvanized gas pipe? Today using galvanized pipe generally presents no threat. If pipe is in the ground it will tend to corrode faster depends on the soil conditions.

Black pipes are also called steel pipes and are used to carry water and gas from their sources to the end users. It is the pipe that is used by businesses and homes to convey their supply of natural or propane gas. It is also used for fire sprinkler systems because of its strong resistance to heat. What type of gas line can be buried?

Polyethylene gas piping systems are specifically engineered and certified for the underground environment.
