Key Features & Benefits at a Glance
- Superior corrosion resistance with black-coated steel construction, extending service life in demanding environments
- Versatile multi-medium compatibility for safe, reliable use with air, natural gas, oil, steam, and water systems
- Robust welded construction ensures leak-proof performance and structural integrity under high-pressure conditions
- Dual-connection flexibility with threaded NPT male end and butt weld socket for easy installation and system integration
- Precision-engineered dimensions (3" Schedule 40, 5" length) maintain consistent flow characteristics and fitting compatibility
- Industry-standard compliance with ASME B1.20.1, ASTM A53, and ASTM A733 guarantees dimensional accuracy and material quality
- Environmental regulation adherence through REACH and RoHS 3 compliance for sustainable industrial operations
Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers exceptional engineering value in industrial fluid handling systems where corrosion resistance and pressure integrity are critical. The welded construction combined with NPT threading on one end and butt weld connection on the other creates a reliable transition point between threaded and welded piping systems. Engineered for air, natural gas, oil, steam, and water applications, it solves common leakage and compatibility issues in Class 125 and 150 iron/steel flange systems. The Schedule 40 wall thickness (0.216") provides optimal strength-to-weight ratio, while the black coating protects against environmental degradation in chemical processing, power generation, and industrial plumbing installations.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 for precise NPT thread dimensions and ASTM A53/A733 material specifications. Features 3" nominal pipe size with 3.068" ID and 3-1/2" OD, maintaining Schedule 40 pressure rating standards. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives. Suitable for use with iron and steel fittings rated for Class 125 and 150 applications.
