Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers exceptional engineering value in industrial fluid handling systems. The welded construction combined with Schedule 40 wall thickness provides superior burst pressure resistance, making it ideal for air, natural gas, oil, steam, and water applications. The NPT threading ensures secure, leak-free connections with iron and steel fittings, while the protective coating minimizes corrosion in humid or chemical environments. Its 5" length and standardized dimensions facilitate quick installation in tight spaces, reducing maintenance downtime in processing plants, HVAC systems, and industrial piping networks where reliable pipe connections are critical for operational continuity.
Specification Summary & Compliance
Manufactured to exact ASME B1.20.1 specifications for NPT thread form and dimensional tolerances. Material compliance with ASTM A53 and ASTM A733 standards ensures consistent mechanical properties and chemical composition. Suitable for Class 125 and 150 flange applications with iron or steel fittings. Dimensions include 1 1/4" pipe size, 1.38" ID, 1 21/32" OD, and 0.14" wall thickness. The straight configuration with male threaded both ends provides standardized compatibility across industrial piping systems.
