Hot Rolled Black Pipe is produced from low-carbon steel to meet the mechanical and pressure requirements of ASTM A53 Grade B. The term 'black' refers to the dark iron oxide scale left on the surface after manufacturing, which provides minimal corrosion protection. This material is known for its excellent weldability using common methods and is designed for coiling, bending, and flanging.
As a large-diameter pipe, this 3" NPS Schedule 40 size is commonly used for significant fluid conveyance and structural roles. It is a reliable choice for main water lines in commercial plumbing, industrial process piping for non-corrosive media, and as strong, load-bearing structural columns in construction and equipment frames.
