3-inch Galvanized Steel Pipe Nipple

This 3-inch nominal pipe size nipple is made from Grade B welded steel with a galvanized coating. It is designed for conveying air, gases, non-potable water, and oils in industrial plumbing systems. The fitting features male NPT threads on one end and threaded both ends for standard connection.

Schedule 40 Pressure Rating

The nipple conforms to Schedule 40 dimensions with an outside diameter of 3 1/2 inches and an inside diameter of 3 1/16 inches. It withstands a maximum operating pressure of 150 psi at 150 degrees Fahrenheit. This rating determines suitability for the intended fluid system.

Threaded Installation Considerations

Installation requires tightening male NPT threads into compatible female fittings using appropriate pipe sealant or tape. The galvanized coating resists corrosion but can be damaged by over-tightening. Ensure the mating threads match the 3-inch NPT standard to prevent leaks.

Questions about this item

What does the 150 psi rating mean when the nipple is installed in a working system?

It sets the maximum operating pressure at 150 psi when the fluid temperature is 150 degrees F.

How does the MNPT x TBE threading affect what the nipple can connect to?

One end has male NPT threads for a female fitting; the other end is plain so it can be threaded or welded on site.

What clearance and mounting method does the 3 1/2 in outside diameter require?

The 3 1/2 in OD needs a matching hole or bracket, and the welded steel body is joined by threading the MNPT end into a female NPT port.
