Asc 4354003250 Black Steel Xh Seamless Nipple 2x4.5 in

Product Description

The ASC ENGINEERED SOLUTIONS 4354003250 is a black steel seamless extra heavy (XH) pipe nipple sized at 2 inches by 4.5 inches. This close-tolerance nipple is manufactured from A106B seamless steel, making it suitable for high-pressure and high-temperature piping applications. The extra heavy wall rating provides added burst resistance compared to standard Schedule 40 fittings. Licensed plumbers, pipefitters, and mechanical contractors use this type of nipple to connect threaded pipe runs in gas, steam, and industrial fluid systems where elevated pressure or mechanical stress is a concern.

This nipple is suited for commercial and industrial piping systems where A106B seamless carbon steel construction is specified. Common applications include steam lines, compressed air headers, gas distribution manifolds, and hydraulic supply runs. The 2-inch diameter and 4.5-inch length make it a practical close nipple for tight-clearance installations and riser connections. It is sourced as an import fitting and is not designated for domestic-origin project requirements.

Key Features

• A106B seamless carbon steel construction for high-pressure service
• Extra heavy (XH) wall rating for increased burst and mechanical load resistance
• Black steel finish suitable for non-potable gas, steam, and industrial fluid lines
• 2 inch x 4.5 inch dimensions for standard threaded pipe connections
• Import designation — not for domestic-origin specification projects

Compatibility

Designed as an OEM-style threaded pipe nipple replacement for 2-inch extra heavy black steel piping systems using A106B seamless carbon steel fittings.

Installation Notes

Installation of threaded steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable IFGC, ASME B31.1, or local mechanical code requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape rated for the service medium before making up the connection. Do not over-torque threaded joints, as this can crack fittings or distort threads.
