Professional Applications & Engineering Value
This galvanized steel threaded pipe nipple delivers critical engineering solutions for industrial fluid transfer systems. The zinc-coated construction actively combats corrosion in aggressive environments containing moisture, chemicals, and temperature variations. Its NPT threaded both ends configuration enables secure, pressure-tight connections between 125-150 class fittings, eliminating leakage risks in air compression, natural gas distribution, hydraulic oil lines, steam transfer, and water supply applications. The welded construction and Schedule 40 wall thickness provide optimal strength-to-weight ratio, resisting deformation under continuous operational stress while maintaining full flow capacity through the precise 1.38" ID.
Specification Summary & Compliance
Manufactured to exacting NPT thread standards per ASME B1.20.1 with Class 2A tolerance for reliable mating compatibility. The galvanized steel material complies with ASTM A53 specifications for seamless and welded steel pipe, while ASTM A733 governs the welded and seamless carbon and austenitic stainless steel pipe nipple requirements. The product meets standard industrial compliance for hazardous substance restrictions and is suitable for pressure applications within specified temperature and pressure ratings for 125-150 class fittings.
