Service Metal scr0403.0 Concentric Reducer 4x3 in Carbon Steel

Product Description

The SERVICE METAL scr0403.0 is a 4-inch by 3-inch carbon steel concentric reducer designed for butt weld installation in industrial and commercial piping systems. Concentric reducers maintain a shared centerline between the inlet and outlet, making them the standard choice for horizontal runs where alignment continuity is required. At 3.30 pounds, this fitting is built to handle the demands of typical process and mechanical piping applications. Installation is performed by qualified pipe welders or pipefitters working within established welding and fabrication standards.

This reducer is suited for use in commercial and industrial piping systems where a reduction from 4-inch to 3-inch nominal pipe size is needed. The concentric design is commonly specified in horizontal piping runs and in systems where a uniform pipe centerline must be maintained through the transition. It is applicable in process piping, mechanical systems, and general trade plumbing or HVAC hydronic configurations that call for butt weld carbon steel fittings.

Key Features

• Concentric design maintains shared centerline between inlet and outlet
• 4-inch x 3-inch nominal size reduction in a single fitting
• Carbon steel construction suited for pressure piping applications
• Butt weld end connection for full-penetration welded joints
• Standard wall configuration for typical service conditions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for carbon steel butt weld piping systems requiring a standard concentric reducer at 4-inch by 3-inch nominal pipe size.

Installation Notes

Installation must be performed by a qualified pipefitter or certified pipe welder in accordance with applicable codes such as ASME B31.3 for process piping or ASME B31.9 for building services piping. Shut down and depressurize the system completely before cutting into existing pipe or fitting the reducer. Ensure pipe ends are clean, properly beveled, and aligned before tack welding. Do not apply heat to pressurized lines.
