2-1/2" Nominal Pipe Size (NPS) Schedule 40 black pipe provides robust performance for fluid transfer and structural uses. Conforming to ASTM A53 Grade B, it features 60,000 PSI tensile strength and excellent weldability, ideal for main water lines and industrial piping. In stock Los Angeles.
- A53B Carbon Steel Construction
- ASTM A53 Certified
- 60,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled black pipe is a carbon steel product manufactured to ASTM A53 Grade B specifications for pressure and mechanical applications. The 'black' designation refers to the dark iron oxide scale on the surface, which provides minimal corrosion protection. It offers excellent weldability and can be easily bent, coiled, and flanged for various industrial systems.
As a large-diameter pipe, this 2-1/2" Sch 40 size is commonly used for main water lines, industrial process piping for non-corrosive fluids, structural columns, and heavy-duty scaffolding. Its substantial wall thickness ensures high pressure ratings and significant load-bearing capacity.
