Midland Industries 59230SMLS Seamless Pipe Nipple Sch 80 Xh

Product Description

The MIDLAND INDUSTRIES 59230SMLS is a seamless black steel pipe nipple rated for demanding industrial and commercial piping applications. Built to Schedule 80/Extra Heavy (XH) wall specifications, this nipple measures 11 inches in overall length with a 4-inch diameter and carries a 2800 psi working pressure rating at a 300 lb pressure class. The 0.337-inch wall thickness delivers the structural integrity required in high-pressure systems. Both ends are threaded male pipe taper (MPT) with 4-8 thread form and 1.74-inch thread length, conforming to ANSI B1.20.1 dimensional standards. Licensed plumbers, pipefitters, and mechanical contractors install this fitting in gas, steam, water, and industrial fluid piping systems.

This nipple is suited for residential and commercial installations where extra-heavy wall strength is required. Typical applications include black iron gas distribution lines, industrial process piping, and steam systems. The seamless construction eliminates weld seams, making it the preferred choice in high-pressure or high-temperature environments. It performs across a temperature range of -200 to 150 degrees F, making it adaptable to a broad range of service conditions. The black finish is standard for natural gas and non-corrosive fluid service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before makeup. Do not use this fitting beyond its rated pressure or temperature limits.
