Key Features & Benefits at a Glance

Superior corrosion resistance with galvanized steel construction, extending service life in harsh industrial environments.
Reliable leak-proof connections through precision NPT threading on both ends, ensuring secure seals for high-pressure applications.
Versatile multi-medium compatibility for safe use with air, natural gas, oil, steam, and water systems.
Enhanced structural integrity from welded construction, providing durability under mechanical stress and vibration.
Broad fitting adaptability with compatibility for Class 125/150 galvanized iron and steel fittings, simplifying installation.
Regulatory peace of mind with full compliance to REACH and RoHS 3, meeting international environmental safety standards.
Precise dimensional consistency per Schedule 40 specifications, guaranteeing seamless integration into existing piping systems.

Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple delivers critical performance in industrial fluid and gas handling systems. The welded construction and NPT threading eliminate common failure points in high-vibration environments, while the zinc coating provides sacrificial protection against rust in humid or chemical-exposed settings. Engineered to ASME B1.20.1 and ASTM A53 standards, it maintains pressure integrity in Class 150 applications across oil, steam, and water services. The 22" length and 1 1/4" diameter optimize it for bridging connections in tight spaces, reducing assembly time and maintenance frequency in plumbing, HVAC, and process piping installations.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 for NPT thread form and ASTM A53 for material quality, this nipple maintains Class 2A thread tolerances. The Schedule 40 wall thickness (0.14") ensures pressure rating consistency, with additional validation per ASTM A733. Full compliance with REACH (SVHC list) and RoHS 3 directives confirms environmental safety, while compatibility with galvanized iron/steel fittings rated Class 125/150 guarantees system-wide standardization.
