Asc Engineered Solutions 4354002840 Black Steel Xh Nipple

Product Description

The ASC ENGINEERED SOLUTIONS 4354002840 is a black steel seamless extra heavy (XH) pipe nipple sized at 1-1/2 inches by 3-1/2 inches. It is manufactured from A106B grade black steel using a seamless construction process, delivering consistent wall thickness and reliable pressure integrity throughout the fitting. This nipple connects threaded pipe runs in high-pressure or high-temperature service applications. Plumbers, pipefitters, and mechanical contractors install this type of fitting in steam, gas, oil, and industrial process piping systems where standard-weight fittings are not rated for the service conditions.

This XH nipple is suited for commercial and industrial piping installations where elevated pressure ratings are required. The 1-1/2-inch by 3-1/2-inch dimensions make it appropriate for close-nipple and short-run connections in tight mechanical spaces. Typical applications include boiler rooms, mechanical penthouses, industrial process lines, and gas distribution headers. The black steel finish is standard for non-potable and non-domestic service lines, including gas and steam systems.

Key Features

• Seamless A106B black steel construction for uniform wall integrity under pressure
• Extra heavy (XH) wall rating for elevated-pressure service beyond standard Schedule 40 applications
• 1-1/2 inch by 3-1/2 inch nominal dimensions for short-run threaded connections
• Black steel finish suitable for gas, steam, and industrial process piping
• Non-domestic (import) sourcing as noted in product specifications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch threaded black steel pipe systems operating in non-domestic, non-potable service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC and ASME B31 standards where relevant. Shut off and depressurize the pipe system fully before removing or installing threaded fittings. Use an appropriate thread sealant rated for the service medium, whether gas, steam, or oil. Do not overtighten threaded connections; follow standard trade practice for the pipe material and service pressure.
