Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical performance advantages in industrial fluid and gas handling systems. The welded construction combined with NPT threading creates robust, pressure-tight connections that prevent leakage in compressed air lines, steam distribution networks, and hydrocarbon processing equipment. Engineered to ASME B1.20.1 and ASTM A53 standards, this Schedule 40 pipe nipple maintains dimensional consistency across high-temperature and high-pressure applications, while the protective coating resists corrosion from moisture, chemicals, and environmental exposure. The 11 1/2" length provides optimal spacing flexibility in piping layouts, making it ideal for connecting valves, pumps, and pressure vessels in manufacturing plants, refineries, and utility systems.

Specification Summary & Compliance

This product features precision NPT threads conforming to ASME B1.20.1 standards with Class 2A thread tolerances for reliable engagement. Manufactured from ASTM A53 and ASTM A733 compliant materials, it maintains Schedule 40 dimensional specifications with 1.61" ID and 1 29/32" OD.
