The BMI USA 20011 is an extra heavy (XH) malleable iron pipe coupling finished in black, designed for joining sections of threaded pipe in demanding plumbing, mechanical, and industrial piping systems. The extra heavy wall construction provides increased strength and durability over standard-weight fittings, making it appropriate for high-pressure or high-stress applications. At 6.82 pounds, this coupling is built for installations where standard malleable iron fittings are not rated for the load or pressure conditions on site. Licensed plumbers and pipefitters are the typical installers for this class of fitting.
This coupling is suited for use in commercial and industrial piping installations where threaded black iron pipe is specified. Common applications include gas distribution piping, fire suppression systems, steam lines, and compressed air systems where extra heavy fittings are required by code or engineering specification. The black finish is standard for gas and steam service applications.
Designed as an OEM-style replacement or direct-use extra heavy malleable iron pipe coupling for threaded black iron pipe systems in commercial, industrial, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or pipe tape to all male threads before assembly. Do not overtighten, as malleable iron threads can crack under excessive torque.
