- A53B Steel Construction
- ASTM A53 Certified
- 60,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled black pipe is manufactured to ASTM A53 Grade B specifications, a standard for carbon steel pipe used in mechanical and pressure applications. The 'black' designation refers to the dark iron oxide scale on its surface from manufacturing, which offers minimal corrosion protection. It's a low-cost, versatile material prized for its strength and excellent weldability for non-critical structural use.
With a substantial 3-1/2 inch nominal pipe size, this Schedule 40 pipe is suited for high-volume applications like main water lines, industrial process piping for non-corrosive fluids, and as primary structural columns or supports in building frames and heavy equipment.

For exterior use or corrosion protection, the scale must be removed before painting, powder coating, or other finishing. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Pipe is measured by its Nominal Pipe Size (NPS), which is a North American standard for pipe used for high or low pressures and temperatures. The actual outside diameter is larger than the NPS. The wall thickness is defined by the Schedule (Sch) number.
Example: To order this pipe, specify "Black Pipe, 3-1/2 inch NPS, Schedule 40 x 21 ft length".
