The MIDLAND INDUSTRIES 56183 is a Schedule 40 galvanized steel welded pipe nipple rated for 2,500 psi working pressure. It measures 4 inches in overall length with a 2.5-inch nominal diameter and male pipe thread (MPT) connections on both ends. The wall thickness is 0.203 inches, and thread length is 1.57 inches per end, conforming to ANSI B1.20.1 dimensional standards. Licensed plumbers and pipefitters install this nipple in commercial and industrial piping systems where corrosion resistance and pressure integrity are required.
This nipple is suited for water supply, gas distribution, and general industrial piping applications operating within a temperature range of -150 to 200 degrees F. The hot-dip galvanized zinc coating provides corrosion protection in wet or outdoor environments. It is commonly used in Schedule 40 threaded piping assemblies in mechanical rooms, plant utilities, and building service plumbing where a short close nipple is needed between fittings or valves.
Designed as a standard replacement or new-installation nipple for Schedule 40 galvanized threaded piping systems using 2.5-inch nominal NPT connections.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC guidelines. Wrap male threads with PTFE tape or apply approved pipe thread compound before assembly to ensure a leak-free joint. Tighten to a secure fit using a pipe wrench on the nipple body, not on the threaded ends, to avoid thread damage. Isolate and depressurize the line fully before removing or installing any threaded fitting.
