Asc 4354001690 Black Steel Xh Pipe Nipple 3/4 X 5.5 in

Product Description

The ASC Engineered Solutions 4354001690 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/4 inch by 5-1/2 inches. Manufactured to ASTM A106B standards, it is designed for use in high-pressure and high-temperature piping systems where standard-wall fittings are not adequate. The seamless construction eliminates a weld seam, reducing the risk of failure under cyclic stress or elevated pressure. This nipple is commonly installed by licensed plumbers, pipefitters, and mechanical contractors working on industrial, commercial, and heavy-duty mechanical piping runs.

This nipple is suited for steam, gas, and liquid piping applications where extra wall thickness is required by design or code. It fits into threaded piping assemblies and is appropriate for commercial mechanical rooms, industrial process lines, and similar high-demand environments. The black steel finish makes it compatible with non-corrosive media applications. Import-sourced product meeting ASTM A106B seamless pipe material specification.

Key Features

• Seamless construction per ASTM A106B — no longitudinal weld seam
• Extra heavy (XH) wall thickness for elevated pressure service
• Black steel material suitable for steam, gas, and non-corrosive liquid service
• Threaded ends for standard NPT piping assembly
• Compact 5-1/2 inch length for close-clearance installations

Compatibility

Designed as an OEM-style threaded replacement nipple for extra heavy black steel piping systems using 3/4 inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not over-torque threaded connections, as this can crack fittings or damage threads.
