Schedule 40 Carbon Steel Black Pipe Nipples

Black steel pipe is manufactured as seamless which makes it a better type for gas transportation and fire sprinkler systems since it can prevent fire better than galvanized pipe. Black iron pipe is also most often use in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage. Since it has a dark color surface which is formed by iron oxide during the manufacturing process, it is called black steel pipe.

The main difference between steel pipe and galvanized pipe lies in the surface. Black steel pipe is uncoated and made without steam, and therefore, it is widely used for transporting gas like propane and natural gas to residential and commercial building.
