Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers exceptional performance in industrial fluid handling systems where corrosion resistance and pressure integrity are critical. The welded construction and Schedule 80 thick-wall design provide superior burst resistance for high-pressure applications involving steam, oil, and natural gas. The NPT threaded ends ensure secure, leak-proof connections in Class 300 and 600 flange systems, while the protective coating minimizes degradation from moisture and chemical exposure. Engineered to withstand thermal expansion and mechanical stress, this 4-inch pipe nipple serves as a reliable component in petrochemical plants, power generation facilities, and industrial processing systems where downtime prevention is paramount.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 specifications for NPT thread standards with dimensional accuracy including 1.278" ID and 1 21/32" OD. Constructed from ASTM A53 and ASTM A733 compliant steel materials, ensuring consistent wall thickness (0.191") and mechanical properties. Suitable for pressure ratings matching Class 300 and 600 flange requirements. The black coating provides additional corrosion protection while maintaining compliance with industrial safety standards for air, gas, oil, steam, and water service applications.
