• NPT threading on both ends ensures secure, standardized connections compatible with Class 6000 fittings and Class 1500 flanges.
• Broad fluid compatibility safely handles air, hydraulic fluid, natural gas, oil, steam, and water without corrosion concerns.
• Precision manufacturing per ASME B1.20.1 guarantees consistent thread fit and easy installation in tight-tolerance assemblies.
• Regulatory compliance with REACH and RoHS 3 ensures environmental safety and global supply chain acceptance.
• Robust 4-inch length provides optimal spacing flexibility in complex piping layouts while maintaining structural integrity.

Professional Applications & Engineering Value

This heavy-duty steel threaded pipe nipple delivers critical reliability in demanding industrial environments where high-pressure fluids and gases pose operational risks. Its seamless construction and XXH schedule wall thickness prevent failure points common in welded alternatives, making it ideal for hydraulic systems, steam lines, and natural gas distribution. The NPT threaded both ends design facilitates quick integration with Class 6000 steel fittings, while ASTM A106/A733 compliance ensures material consistency across temperature variations. Engineers specify this super-thick-wall pipe nipple to minimize maintenance downtime and leakage in chemical processing, power generation, and oil refineries where system integrity is non-negotiable.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 for precise NPT thread standards with Class 2A tolerances ensuring leak-resistant connections. Material certifications include ASTM A106 for seamless carbon steel tubing and ASTM A733 for welded and seamless carbon steel pipe. Full compliance with REACH (EC 1907/2006) substance restrictions and RoHS 3 (2015/863/EU) directives confirms environmental responsibility. Dimensional accuracy maintained at 1 1/2" pipe size, 4" length, and 1.1" ID for consistent performance in Class 1500 flange and Class 6000 fitting applications.
