A 3/4-inch Schedule 40 hot rolled black pipe designed for pressure and mechanical applications. Conforming to ASTM A53 Grade B, it provides a minimum tensile strength of 60,000 PSI and excellent weldability, making it ideal for plumbing, gas lines, and light structural frames. In stock Los Angeles.
- A53B Carbon Steel Construction
- ASTM A53 Grade B Certified
- 60,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled black pipe is a carbon steel product manufactured to ASTM A53 Grade B standards. The term 'black' refers to the dark iron oxide scale left on the surface during manufacturing, which offers minimal corrosion resistance. It is strong, formable, and easily welded, making it a reliable and economical choice for non-potable fluid and gas conveyance systems.
As a small NPS pipe, this 3/4-inch size is perfectly suited for instrumentation lines, residential natural gas connections, compressed air piping, and small-scale structural applications like handrails, decorative frames, and posts where high pressure ratings are not the primary concern.

Finish Options
This product comes standard with a black mill finish, which is the iron oxide scale formed during the hot rolling process. This offers minor, temporary protection against rust. For corrosion resistance, the scale must be removed before painting, powder-coating, or oiling. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Pipe is measured by its Nominal Pipe Size (NPS) and Schedule. NPS is a North American standard for pipe sizes, and the Schedule number (e.g., Sch 40) indicates the wall thickness. The actual outside diameter is different from the NPS.
Example: To order this pipe, specify "Black Pipe, 3/4 Inch NPS, Schedule 40".
