Bmi Usa 20111 3 Inch Xh Black Malleable Iron Pipe Union

Product Description

The BMI USA 20111 is a 3-inch extra heavy (XH) black malleable iron pipe union designed for threaded pipe assemblies in demanding service environments. Malleable iron construction provides the ductility and strength required for high-stress piping systems, while the black finish indicates this union has not been galvanized, making it suitable for gas, steam, and oil service applications. At 11.02 pounds, this is a robust fitting built for industrial and commercial-grade installations. It is installed by licensed plumbers, pipefitters, and HVAC technicians working on medium to large-bore piping systems.

This union is appropriate for use in commercial and industrial piping systems where a 3-inch threaded connection must be broken and reassembled without disturbing the rest of the line. Extra heavy wall ratings make it well suited for steam, gas distribution, compressed air, and similar higher-pressure service lines. It is commonly found in boiler rooms, mechanical rooms, and industrial process piping installations.

Key Features

• Extra heavy (XH) malleable iron construction for high-strength threaded piping applications
• 3-inch pipe size for medium to large-bore installations
• Black finish suitable for gas, steam, and oil service where galvanized coatings are not appropriate
• Threaded union design allows disconnection and reconnection of piping without cutting
• Weighs 11.02 pounds, consistent with extra heavy wall material thickness

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch threaded pipe systems requiring extra heavy malleable iron unions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including the IPC and IFGC where relevant. Shut off and depressurize the line completely before breaking any existing union or installing this fitting. Apply appropriate thread sealant or tape rated for the intended service medium. Do not over-tighten the union nut, as malleable iron threads can be damaged by excessive torque.
