Professional Applications & Engineering Value

This heavy-duty threaded pipe nipple addresses critical industrial challenges where corrosion resistance and high-pressure containment are paramount. The black-coated steel construction combined with Schedule 80 wall thickness provides exceptional durability against internal pressure surges and external environmental factors. Engineered specifically for demanding industrial piping systems handling air, natural gas, oil, steam, and water, the NPT threaded ends ensure secure, leak-resistant connections that maintain system integrity under continuous operation. The welded construction enhances structural reliability, making it ideal for Class 300 and 600 flange applications where failure is not an option. This 11-inch pipe nipple delivers consistent performance in chemical plants, oil refineries, and power generation facilities, reducing maintenance frequency and downtime.

Specification Summary & Compliance

This 1 1/2" Schedule 80 threaded pipe nipple features precise NPT threading conforming to ASME B1.20.1 standards for reliable sealing performance. Manufacturing complies with ASTM A53 for material composition and ASTM A733 for welded construction requirements. The product maintains dimensional accuracy with 11-inch length, 1.5" ID, and 1 29/32" OD specifications, ensuring proper fitment in Class 300 and 600 steel flange systems. Wall thickness of 0.2" provides the necessary strength for high-pressure applications while meeting industry standards for industrial pipe fittings used with air, natural gas, oil, steam, and water services.
