S-44615K546 1.049" ID x 1 5/16" OD x 12" Long ASME B1.20.1, ASTM A53, ASTM A733 Standard-Wall Steel Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Corrosion-resistant black coating extends service life in demanding environments with air, gas, oil, steam, and water systems
• Welded steel construction ensures superior structural integrity and leak-proof performance under high-pressure conditions
• NPT threads on both ends provide secure, standardized connections compatible with iron and steel fittings (Class 125/150)
• Precise 1" Schedule 40 dimensions guarantee consistent fit and optimal flow characteristics in industrial piping networks
• ASTM A53/A733 certified material delivers proven mechanical strength and durability for heavy-duty applications
• 12-inch length versatility accommodates flexible spacing requirements while maintaining full-thread engagement
• Multi-medium compatibility eliminates cross-contamination risks when transitioning between air, gas, oil, steam, and water systems

Professional Applications & Engineering Value

Engineered to solve critical connectivity challenges in industrial fluid systems, this black-coated steel threaded pipe nipple combines welded construction with NPT threading to prevent leakage in high-vibration environments. The Schedule 40 wall thickness (0.133") maintains pressure integrity while the black coating resists corrosion from steam, oil, and chemical exposure. Ideal for connecting iron/steel flanges in Class 125/150 systems, it eliminates material compatibility issues when handling natural gas, compressed air, hydraulic oil, and process water. The standardized 1" pipe size and 12" length enable rapid installation in tight spaces while meeting dimensional requirements for plant maintenance and OEM equipment manufacturing.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 specifications for precise NPT thread form and engagement. Material compliance with ASTM A53 (standard for welded steel pipe) and ASTM A733 (welded/unwelded carbon steel tubing) ensures consistent mechanical properties. Dimensional conformance to Schedule 40 standards (1.049" ID, 1-5/16" OD) with Class 2A thread tolerances for reliable sealing. Suitable for systems operating with air, natural gas, oil, steam, and water within pressure ratings for 125/150 class fittings.
