- Long-term cost efficiency through durable ASTM A53/A733 compliance, reducing replacement frequency
Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers critical performance in industrial fluid and gas transfer systems. The welded construction combined with NPT threading creates a vibration-resistant connection point that prevents leakage in pressurized applications ranging from steam lines to hydraulic oil circuits. Engineered to ASTM A53 standards, it maintains dimensional stability under thermal cycling and mechanical stress, while the protective coating resists oxidation in humid or chemical-exposed environments. Its compatibility with Class 125/150 fittings makes it ideal for connecting iron and steel components in processing plants, HVAC systems, and industrial machinery where reliability is paramount.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 for precise NPT thread form and Class 2A tolerance, ensuring interchangeability. Meets ASTM A53 (material composition) and ASTM A733 (welded construction) specifications. Dimensions: 1 1/4" Schedule 40 (1.38" ID, 1 21/32" OD) with 2" length. Suitable for systems operating with air, natural gas, oil, steam, and water. Complies with industry standards for pressure-rated applications.
