Sch. 40 Black Steel Pipe

Schedule 40 black steel pipe is a medium-wall carbon steel piping product widely used in HVAC, fire protection, plumbing, gas distribution, and industrial mechanical systems. It is commonly specified for sprinkler systems, air distribution, hydronic heating, and process piping applications where strength, durability, and pressure handling are required. Unlike galvanized pipe, black steel pipe has no zinc coating, making it suitable for welding and high-temperature applications. This category includes welded steel pipe in standard lengths and diameters and is typically joined using threaded, grooved, welded, or mechanical coupling methods depending on system requirements. Schedule 40 black steel pipe is widely used in commercial, industrial, and institutional construction.
