SHD40-3/4-10.5 - 3/4 Inch Schedule 40 Black Steel Pipe - 10.5 Foot Length

Industrial Grade Schedule 40 Black Iron Pipe

The SHD40-3/4-10.5 Black Iron Pipe is a premium-grade piping solution designed to meet the rigorous demands of industrial, commercial, and residential infrastructure. Manufactured to Schedule 40 standards, this pipe provides the optimal balance between wall thickness and flow capacity, making it the industry standard for transporting low to medium-pressure fluids and gases. The "Black Iron" designation refers to the dark-colored iron oxide scale formed on the surface during the manufacturing process, which is often supplemented with a protective varnish to prevent corrosion prior to installation.

With a nominal pipe size (NPS) of 3/4 inch, this pipe actually features an outside diameter of approximately 1.050 inches, adhering to standardized dimensional specifications that ensure compatibility with a vast array of fittings, valves, and flanges. The 10.5-foot length is particularly advantageous for jobs requiring longer runs without the need for excessive coupling, yet it remains manageable for transport and handling on the job site. This pipe is commonly employed in the distribution of natural gas and propane, as well as in steam heating systems where the durability of steel is required to withstand thermal cycling and pressure.

Unlike galvanized pipe, black iron pipe does not have a zinc coating, which makes it unsuitable for potable water due to the risk of corrosion over time. However, this lack of zinc is a significant benefit for gas lines, as zinc can flake off and clog regulators. Furthermore, the absence of galvanization makes this pipe ideal for closed-loop fire sprinkler systems and compressed air lines where moisture content is controlled. The steel composition allows for reliable performance under mechanical stress, ensuring the safety and longevity of your piping infrastructure.

Installation versatility is a key feature of this product. It can be threaded using standard NPT dies for screw-fit connections, grooved for mechanical couplings, or welded for permanent, leak-proof joints. Whether you are repairing an existing boiler feed line or installing a new gas manifold, this Schedule 40 pipe delivers the consistency and quality required for code-compliant installations.
