Professional Applications & Engineering Value
This black-coated steel pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. The welded construction combined with NPT threaded ends delivers exceptional leak resistance when transporting aggressive media like steam, oil, and natural gas. Its Schedule 40 rating and compatibility with Class 125/150 flanges make it ideal for maintaining system integrity in high-pressure environments. The corrosion-resistant coating prevents degradation from moisture and chemicals, reducing maintenance frequency in plants, refineries, and HVAC installations. By integrating threaded and socket weld options, it provides flexible connection solutions while adhering to ASME B1.20.1 threading standards for precise, reliable fits.
Specification Summary & Compliance
This 1 1/2" NPT threaded pipe nipple features precision threading per ASME B1.20.1 standards, ensuring Class 2A fit for leak-tight connections. Manufactured from ASTM A53/A733 steel with Schedule 40 dimensions (1.61" ID, 1 29/32" OD, 0.145" wall thickness), it guarantees dimensional accuracy for iron and steel fittings. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, meeting environmental and safety requirements for industrial applications.
