Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple is engineered to solve critical challenges in industrial piping systems. The zinc coating provides a sacrificial layer that significantly reduces rust and corrosion, a common failure point in systems handling steam, water, and natural gas. Its welded construction and Schedule 40 standard wall thickness ensure it can withstand the mechanical stress and pressure fluctuations typical in HVAC, process lines, and plant utility services. The precision-machined NPT (National Pipe Taper) threads on both ends create a pressure-tight seal with mating galvanized iron or steel fittings, preventing leaks in Class 150 flange applications. This combination of material and design delivers long-term reliability, minimizing downtime and replacement costs in demanding industrial settings.

Specification Summary & Compliance

This product features a pipe size of 2 1/2", a length of 5 1/2", and conforms to NPT thread standards per ASME B1.20.1. It is manufactured from galvanized steel in accordance with ASTM A53 (specifying standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded and seamless) and ASTM A733 (covering welded and seamless carbon and austenitic stainless steel pipe nipples). The construction and materials ensure compliance with common industry pressure and safety standards for the specified applications.
