Asc Engineered Solutions 766259089 Weldolet 4 in Carbon Steel

Product Description

The ASC ENGINEERED SOLUTIONS 766259089 is a standard-weight carbon steel weldolet designed for branch outlet connections in industrial and commercial piping systems. This fitting creates a full-penetration welded branch takeoff from a 10-inch or 8-inch run pipe to a 4-inch outlet, maintaining structural integrity and flow characteristics required in high-demand pipe networks. At 4.37 pounds, the fitting is sized for applications where pressure retention and weld quality are critical. It is installed by certified welders or pipefitters working on process, mechanical, or utility piping systems.

This weldolet is suited for carbon steel piping systems in industrial, commercial, and mechanical contractor applications. It is commonly used in process piping, steam distribution, HVAC hydronic mains, and utility headers where a branch connection must match the strength class of the run pipe. The standard-weight designation aligns it with Schedule 40 equivalent run pipe in most configurations. Pipefitters and welding professionals select this fitting when a reinforced, full-fusion branch outlet is specified over threaded or socket alternatives.

Key Features

• Carbon steel construction for strength and weldability in demanding piping environments
• Standard-weight class suits Schedule 40 equivalent run pipe applications
• 4-inch outlet provides a full-penetration branch takeoff from 10-inch or 8-inch run pipe
• Weld connection type ensures a leak-free, pressure-rated branch joint
• Compact form factor at 4.37 pounds simplifies handling during fit-up and tacking

Compatibility

Designed as an OEM-style replacement and standard fitment weldolet for carbon steel piping systems with 10-inch or 8-inch run pipe and a 4-inch branch outlet requirement.

Installation Notes

Installation must be performed by a qualified pipefitter or certified welder in accordance with applicable codes such as ASME B31.1 or B31.3. De-energize, depressurize, and fully isolate the run pipe before cutting the branch opening and fitting up the weldolet. Use proper fit-up tools and back-purging practices as required by the weld procedure specification. Do not substitute filler materials or skip post-weld inspection steps required by the governing piping code.
