Professional Applications & Engineering Value

This heavy-duty 6061 aluminum threaded pipe solves critical challenges in industrial fluid handling systems. The seamless construction eliminates potential failure points that commonly occur in welded pipes, while the NPT threaded ends ensure leak-proof connections in compressed air, hydraulic oil, and water transport applications. Engineered to ASTM B241 standards, this pipe maintains precise dimensional stability with its 1.38" ID and 1 21/32" OD, preventing flow restrictions and pressure drops. The aluminum material provides natural corrosion resistance without requiring additional coatings, making it ideal for environments where steel pipes would deteriorate. Compatible with 150 class fittings and 125 class flanges, this versatile component serves as both primary piping and connecting nipple in various industrial configurations.

Specification Summary & Compliance

This standard-wall aluminum threaded pipe features NPT (National Pipe Taper) threads on both male ends with Class 2A tolerance for secure fitting engagement. The pipe conforms to ASTM B241 specifications for aluminum alloy drawn seamless pipes, ensuring consistent wall thickness (0.14") and dimensional accuracy throughout the 72-inch length. The product is RoHS 3 (2015/863/EU) compliant and meets environmental standards for restricted substances. Suitable for use with aluminum fittings (150 class) and aluminum flanges (125 class), this pipe maintains Schedule 40 dimensions with 1.38" internal diameter and 1 21/32" outer diameter.
