Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers exceptional engineering value through its welded construction and NPT threading, specifically designed to address common industrial challenges. The Schedule 40 wall thickness (0.133") provides optimal strength-to-weight ratio while maintaining flow capacity, making it ideal for air, natural gas, oil, steam, and water applications where pressure fluctuations and thermal cycling are common. The black coating offers enhanced corrosion protection, significantly extending service life in demanding environments where moisture, chemicals, or temperature variations would compromise standard fittings. Engineered for compatibility with iron and steel fittings in Class 125 and 150 systems, this 9-inch straight pipe nipple ensures leak-free connections and reduces maintenance downtime across industrial plumbing, process piping, and mechanical systems.

Specification Summary & Compliance

This 1" Schedule 40 pipe nipple features precision NPT threading manufactured to ASME B1.20.1 standards for consistent thread engagement and sealing performance. The product complies with ASTM A53 for material composition and ASTM A733 for welded and seamless carbon steel pipe specifications, ensuring dimensional accuracy and mechanical properties suitable for industrial applications. The construction meets standard pipe tolerances with 1.049" ID and 1 5/16" OD dimensions, providing reliable performance in systems requiring Class 125 and 150 fittings compatibility.
