The MIDLAND INDUSTRIES 52146 is a Schedule 80 seamless pipe nipple machined from 316 stainless steel, designed for high-pressure piping systems where corrosion resistance and structural integrity are critical. It measures 4.5 inches in length with a 1.5-inch outside diameter and carries male pipe thread (MPT) connections on both ends sized to 1-1/2-11-1/2 thread per ANSI/ASME B1.20.1. The Schedule 80 wall thickness supports a pressure rating of 3000 psi, making it suitable for demanding industrial and commercial service. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.
This nipple is rated for use in air, water, oil, natural gas, and steam service applications. Its seamless 316 stainless steel construction makes it well suited for corrosive environments, including marine, chemical processing, food service, and commercial plumbing systems. It is a direct-fit threaded component used when a short close nipple extension is needed between threaded fittings, valves, or equipment in SCH 80 piping runs.
Designed for use in SCH 80 threaded piping systems handling air, water, oil, natural gas, and steam service. Fits standard 1-1/2-inch MPT threaded fittings and valves conforming to ANSI/ASME B1.20.1 thread standards.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IPC and IFGC requirements for the service type. Isolate and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant rated for the intended service medium. Do not overtighten threaded connections, as this can damage the threads or fitting body.
