Welding Fittings-standard 3 X 1-1/2 Weld Tee Std

Product Description

The WELDING FITTINGS-STANDARD 3 X 1-1/2 is a standard-wall (STD) weld tee fitting designed for pipe systems requiring a branch outlet connection. The run measures 3 inches and the branch outlet measures 1-1/2 inches, making this a reducing tee configuration. It is joined by butt-welding to mating pipe ends, producing a permanent, full-penetration joint. This type of fitting is installed by certified pipe welders and pipefitters working on process, industrial, or mechanical piping systems where threaded or flanged connections are not specified.

This weld tee is suited for use in industrial piping, mechanical systems, and process lines where a reducing branch connection is required. The STD wall specification aligns with standard ANSI/ASME pipe schedules for 3-inch run pipe. It is sold as a single unit and is appropriate for applications where a butt-weld branch takeoff is required at a reduced diameter from the main run.

Key Features

• Reducing weld tee configuration: 3-inch run by 1-1/2-inch branch outlet
• Standard wall (STD) specification for compatibility with standard schedule piping
• Butt-weld end connections for a permanent, full-penetration joint
• Sold as a single fitting unit

Compatibility

Designed as an OEM-style replacement or new-install weld tee for standard-wall piping systems requiring a 3-inch by 1-1/2-inch reducing branch connection.

Installation Notes

Installation requires a qualified pipe welder or certified pipefitter following applicable codes such as ASME B31.3 or B31.1 for process and power piping. The system must be fully depressurized, drained, and isolated before cutting in or replacing any weld fitting. End preparation, fit-up, and weld procedure must meet the governing piping specification. Do not apply heat to a pressurized or fluid-containing line.
