Midland Industries 49202 Welded Pipe Nipple 3in Sch 40 316 Ss

Product Description

The MIDLAND INDUSTRIES 49202 is a welded pipe nipple designed for threaded pipe systems requiring a short close-length connection between fittings, valves, or equipment. Constructed from 316 stainless steel, it offers strong resistance to corrosion and oxidation in demanding service environments. The nipple measures 3.5 inches in length with a 3-inch diameter and carries a Schedule 40 wall rating, supporting working pressures up to 150 psi. Both ends are male pipe thread (MPT), conforming to ANSI B1.20.1 thread standards. Plumbers, pipefitters, and mechanical contractors install this type of fitting in process piping, chemical handling, and industrial fluid systems.

This nipple is suited for residential and commercial plumbing and industrial piping applications where corrosion resistance and pressure integrity are required. The 316 stainless steel construction makes it appropriate for use in corrosive environments, including salt water exposure, chemical processing lines, and food-grade or sanitary adjacent systems. It is commonly used to extend or connect threaded components in Schedule 40 stainless piping systems.

Key Features

• 316 stainless steel construction for superior corrosion resistance compared to 304 SS
• Schedule 40 wall rating supports up to 150 psi working pressure
• Both ends are 3-inch MPT conforming to ANSI B1.20.1 thread standard
• 3.5-inch overall length suitable for close-coupled fitting connections
• Welded construction for consistent wall integrity along the nipple body

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 threaded stainless steel pipe systems using 3-inch MPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME piping codes. Shut down and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before threading the nipple into place. Do not over-torque threaded connections, as stainless steel threads are susceptible to galling.
