Asc Engineered Solutions 4354001250 Black Steel Nipple

Product Description

The ASC Engineered Solutions 4354001250 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/2 inch by 3-1/2 inches. Manufactured to ASTM A106B standards, this nipple is designed for use in high-pressure and high-temperature piping systems where a seamless, heavy-wall connection is required. The extra heavy wall thickness provides additional strength over standard-weight nipples, making it suitable for demanding industrial and commercial applications. Licensed plumbers and pipefitters typically specify this type of nipple where system pressure ratings and code requirements call for heavier pipe schedule construction.

This nipple is used in commercial and industrial piping systems, including steam, gas, oil, and water distribution lines where black steel pipe is specified. The 1/2 inch by 3-1/2 inch dimension suits close-quarter connections requiring a short threaded run between fittings, valves, or equipment ports. It is commonly installed in mechanical rooms, boiler rooms, and process piping assemblies. The black steel construction makes it appropriate for non-potable water, gas, and steam service where corrosion protection will be applied externally.

Key Features

• Extra heavy (XH) wall construction for elevated pressure service
• Seamless ASTM A106B black steel material for consistent wall integrity
• 1/2 inch by 3-1/2 inch size suits compact fitting-to-fitting connections
• Threaded ends compatible with standard NPT fittings and valves
• Black steel finish appropriate for gas, steam, and non-potable piping

Compatibility

Designed as an OEM-style replacement or new-installation component for black steel threaded piping systems requiring 1/2 inch NPT extra heavy seamless nipples.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the system completely before removing or installing any threaded piping components. Apply an approved thread sealant or PTFE tape to NPT threads before assembly. Do not over-tighten threaded connections, as this can damage threads or crack fittings.
