Key Features & Benefits at a Glance

Corrosion-resistant black coating extends service life in demanding environments with air, natural gas, oil, steam, and water.
Robust welded construction ensures leak-proof integrity and superior pressure handling for Class 125 and 150 iron/steel flanges.
Dual-connection versatility with threaded (NPT) and butt weld/socket weld options simplifies installation in complex piping systems.
Precision NPT threading per ASME B1.20.1 guarantees secure, standardized fits with iron and steel fittings to prevent fluid loss.
Schedule 40 standard-wall thickness provides optimal strength-to-weight ratio for industrial pressure applications.
Full compliance with REACH & RoHS 3 eliminates hazardous substance risks, ensuring workplace safety and regulatory adherence.
ASTM A53/A733 certified steel material delivers consistent mechanical properties for long-term reliability under thermal and mechanical stress.

Professional Applications & Engineering Value

This black-coated steel pipe nipple solves critical sealing and durability challenges in industrial fluid transfer systems. The welded construction combined with NPT threading creates a permanent, high-pressure seal for aggressive media like steam and oil, while the butt weld/socket connect option allows seamless integration into welded pipelines. Engineered to ASME B1.20.1 and ASTM A53 standards, it maintains dimensional accuracy across thermal cycles, preventing joint failure in air, gas, oil, steam, and water applications. The Schedule 40 wall thickness balances pressure containment with flow efficiency, making it ideal for plant maintenance and OEM equipment manufacturing where leak prevention is paramount.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 for precise NPT thread Class 2A tolerances, this nipple meets ASTM A53 (material) and ASTM A733 (welded construction) specifications. Dimensions include 1 1/2" pipe size, 4 1/2" length, 1.61" ID, and 0.145" wall thickness. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives.
