Professional Applications & Engineering Value
This heavy-duty black-coated steel threaded pipe nipple delivers critical performance in demanding industrial fluid handling systems. The welded construction combined with Schedule 80 thick-wall design provides exceptional burst pressure resistance, making it ideal for high-pressure steam, oil, and gas applications where system integrity is paramount. The NPT threaded ends ensure secure, leak-resistant connections with iron and steel fittings, while the protective black coating significantly enhances corrosion resistance in humid or chemically aggressive environments. Engineered specifically for Class 300/600 flanges, this pipe nipple solves critical connection challenges in petrochemical, power generation, and industrial processing systems where reliability cannot be compromised.
Specification Summary & Compliance
This 1/8" Schedule 80 pipe nipple features NPT threading conforming to ASME B1.20.1 standards with dimensional specifications of 3-1/2" length, 0.215" ID, and 13/32" OD. Manufactured from ASTM A53/ASTM A733 compliant steel materials, it meets rigorous industrial requirements for pressure-rated applications. The product maintains precise threading tolerances and wall thickness (0.095") to ensure proper fitment and performance in Class 300/600 flange systems handling air, natural gas, oil, steam, and water services.
