Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid and gas transfer systems. The welded construction combined with NPT threading creates reliable, pressure-tight seals that prevent leakage in high-vibration environments. Its Schedule 40 wall thickness provides optimal strength-to-weight ratio for handling aggressive media including steam, oil, and natural gas. The protective black coating significantly enhances corrosion resistance in humid or chemically exposed installations, while the standardized 3" diameter and 8" length ensure compatibility with existing iron and steel infrastructure. This male threaded pipe nipple serves as a vital connection component in processing plants, utility distribution networks, and industrial machinery where failure prevention is paramount.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread form per ASME B1.20.1 specifications, ensuring proper engagement and sealing performance. The 3.068" ID and 3 1/2" OD maintain precise dimensional tolerances for consistent fitment. Compliance with ASTM A53 (standard for seamless and welded steel pipe) and ASTM A733 (welded and seamless carbon steel mechanical tubing) verifies material quality and manufacturing consistency. Suitable for Class 125 and 150 fittings, this pipe nipple meets industry requirements for pressure-rated applications while adhering to relevant industrial safety and performance standards.
