The ASC ENGINEERED SOLUTIONS 766258834 is a carbon steel weldolet fitting designed for branch connections on piping systems. It serves a 3-1/2 inch run pipe with a 2 inch by 1-1/2 inch branch configuration and is manufactured to standard weight. Weldolets provide a reinforced, full-penetration welded branch outlet without the need for separate reinforcement pads. This fitting is used in industrial, commercial, and mechanical piping systems where pressure-rated branch take-offs are required. Installation is performed by licensed pipefitters and plumbers working on carbon steel piping assemblies.
This weldolet is suited for standard-weight carbon steel piping systems requiring a reliable, weld-type branch outlet. Typical applications include process piping, mechanical rooms, and industrial distribution headers where butt-weld branch connections are specified. The fitting integrates directly into the run pipe via a contour-cut and full-penetration weld, providing a robust outlet that conforms to standard piping design practices.
Designed as an OEM-style replacement and standard weldolet fitting for carbon steel piping systems requiring weld-type branch outlets at standard weight ratings.
Installation must be performed by a qualified pipefitter or welder with appropriate certifications for carbon steel pipe welding. Depressurize and isolate the piping system completely before cutting the branch opening and fitting the weldolet. The run pipe must be contour-cut to match the weldolet saddle profile prior to welding. Follow applicable codes including ASME B31.1 or B31.3 and local mechanical codes for weld procedure, inspection, and testing requirements.
