The WILLIAMS COMFORT PRODUCTS 67034621290 is a 4 x 3 inch standard concentric weld reducer fitting manufactured to SA234 WPB material specification. This fitting is designed to transition pipe flow from a 4-inch line to a 3-inch line in a centered, concentric orientation. The butt-weld end connection provides a full-penetration joint suited for high-integrity piping systems. Licensed pipefitters and welders install this type of fitting in process, industrial, and mechanical piping systems where a smooth, inline diameter reduction is required.
This concentric reducer is appropriate for use in carbon steel piping systems operating in commercial and industrial environments. The SA234 WPB material grade is a standard wrought carbon steel specification commonly used in moderate-temperature pressure piping. Standard-weight wall construction suits typical system pressure ratings in process and mechanical piping applications.
Designed as an OEM-style replacement or new-installation fitting for standard carbon steel butt-weld piping systems with a 4-inch to 3-inch diameter reduction requirement.
Installation must be performed by a qualified pipefitter or certified welder following applicable code requirements such as ASME B31.3 or ASME B31.1. Depressurize and isolate the piping system completely before cutting into any existing line. Fit-up, tack welding, and final weld procedures should conform to the applicable welding procedure specification for SA234 WPB material. Post-weld inspection requirements vary by system classification and local jurisdiction.
