Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers critical performance in industrial fluid handling systems where corrosion prevention and pressure integrity are paramount. The welded construction combined with NPT threading creates reliable, leak-free connections for aggressive media including steam, oil, and natural gas. Engineered to ASME B1.20.1 standards, the precision threads ensure compatibility with iron and steel fittings while the Schedule 40 wall thickness maintains system safety under Class 125/150 pressures. The protective black coating significantly extends service life in humid or chemically exposed environments, reducing maintenance frequency and downtime in processing plants, pipeline systems, and industrial machinery applications.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 thread specifications with dimensional compliance to ASTM A53 and ASTM A733 standards. Features NPT (National Pipe Taper) thread form with Class 2A tolerance for secure mating. The 4" nominal size provides 4.026" ID and 4 1/2" OD with 0.237" wall thickness. Suitable for use with iron and steel fittings rated for Class 125 and 150 applications. Material composition and manufacturing processes adhere to industry standards for pressure system components.
