Asc Engineered Solutions 4354002440 Black Steel Xh Nipple

Product Description

The ASC Engineered Solutions 4354002440 is a black steel seamless extra heavy (XH) pipe nipple sized at 1-1/4 inches by 3-1/2 inches. Manufactured to ASTM A106B standards, this nipple is designed for high-pressure and high-temperature piping systems where standard-wall fittings are insufficient. The seamless construction eliminates weld seams, reducing weak points in demanding service conditions. Licensed plumbers and pipefitters install this type of fitting in commercial and industrial piping assemblies, steam systems, and high-pressure gas distribution lines. At 0.77 pounds, it provides the wall thickness and durability required for extra heavy service classifications.

This nipple is suited for use in commercial and industrial mechanical systems that require extra heavy wall pipe connections. Typical applications include steam distribution, high-pressure gas piping, and industrial process piping where elevated pressure ratings are necessary. The 1-1/4-inch nominal pipe size and 3-1/2-inch length make it a common close-nipple connector between fittings, valves, and equipment flanges in these systems. It is designated as a non-domestic import product.

Key Features

• Seamless construction per ASTM A106B eliminates weld seams for improved pressure integrity

Compatibility

Designed as an OEM-style replacement or standard fitting for extra heavy black steel piping systems using 1-1/4-inch nominal pipe thread connections in commercial and industrial applications.

Installation Notes

Installation of black steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC and ASME B31 standards where applicable. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply appropriate pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-tighten threaded connections, as this can damage threads and compromise the seal.
