Black Steel Pipe

Black steel pipe, also known as black iron pipe, is a type of steel pipe that has not been galvanized or coated with zinc. This lack of coating not only keeps costs lower but also allows these pipes to handle high pressures, making them ideal for distributing natural gas and heating systems. In industrial applications, black steel pipes provide robust solutions for firefighting systems. These systems require resilience against high-pressure water flow and potential temperature fluctuations, roles that black pipes perform exceptionally well due to their simple yet strong design.

Black steel pipe sizes are typically defined by a nominal diameter (also known as NPS or NB) and a schedule (SCH), which indicates the wall thickness. Common sizes range from 1/2 inch to 12 inches, but larger and smaller sizes are also available. Schedules like SCH 40 and SCH 80 are common, with higher schedule numbers indicating thicker walls.
