Professional Applications & Engineering Value
Engineered for demanding industrial fluid transfer systems, this galvanized steel threaded pipe nipple solves critical corrosion and pressure management challenges. The zinc-coated construction creates a sacrificial barrier against rust in chemical exposure and outdoor installations, while the welded Schedule 40 structure withstands pulsating pressures in compressor lines and steam distribution. Its NPT threading (conforming to ASME B1.20.1) ensures zero-leak junctions when paired with galvanized iron/steel fittings in Class 150 flange assemblies. From natural gas processing plants to high-temperature water pipelines, the nipple’s ASTM A53 certification guarantees consistent performance across energy, manufacturing, and utility sectors.
Specification Summary & Compliance
Manufactured to ASTM A53 and ASTM A733 material standards with threading conforming to ASME B1.20.1 specifications. Dimensional accuracy includes 4" nominal pipe size, 4.026" ID, and 0.237" wall thickness per Schedule 40 requirements. Compatible with Class 125/150 fittings and Class 150 flanges in galvanized materials. RoHS and REACH compliance verified for industrial use with air, natural gas, oil, steam, and water media.
