Anvil 0332648401 Black Steel Pipe Nipple 3 in Sch 80

Product Description

The ANVIL 0332648401 is a Schedule 80 black steel threaded pipe nipple designed for use in high-pressure piping systems where standard Schedule 40 wall thickness is insufficient. At 3 inches in diameter and 12 inches in length, this nipple provides a close-coupled threaded connection between fittings, valves, or equipment in gas, steam, air, or water distribution lines. The black finish coating is standard for gas and industrial applications. Licensed plumbers, pipefitters, and HVAC contractors install this type of nipple as part of iron pipe system assemblies requiring full-port flow and robust mechanical strength.

This nipple is suited for commercial and industrial piping installations where Schedule 80 wall thickness is specified by code or design. Common applications include natural gas distribution headers, steam lines, compressed air systems, fire suppression supply lines, and hydronic heating mains. The 3-inch diameter makes it appropriate for high-flow mains and trunk lines in large mechanical systems. It is also used in retrofit and repair work where existing Schedule 80 iron pipe systems require extension or modification.

Key Features

• Schedule 80 wall thickness provides greater pressure rating than Schedule 40 for demanding service conditions
• 3 inch nominal pipe size with NPT threads on both ends for standard iron pipe system compatibility
• 12 inch length suits close-coupled connections and short offset runs between fittings
• Black finish coating standard for gas service and indoor industrial piping
• Weighs 9.82 pounds, indicating full-weight Schedule 80 construction

Compatibility

Designed for use in standard NPT threaded iron pipe systems requiring 3-inch nominal Schedule 80 pipe nipples. Mates with standard 3-inch NPT fittings, valves, flanges, and couplings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical codes such as the IPC or IFGC. Isolate and depressurize the line completely before removing or installing any threaded pipe component. Apply listed thread sealant or PTFE tape rated for the specific service medium before making up the joint. Tighten to a snug fit using pipe wrenches sized appropriately for 3-inch iron pipe, and inspect for leaks before returning the system to service.
