3-Inch Schedule 40 Galvanized Steel Pipe Nipple

This Beck C. H. nipple is a close-threaded male NPT fitting made from Grade A welded steel with a galvanised coating. It carries a nominal size of three inches and is manufactured in the USA. The part is rated for 150 psi at 150 degrees Fahrenheit. It suits air, gas, oil, steam and water distribution in compatible Schedule 40 piping systems.

Installers needing a standard Schedule 40 connection

The nipple matches Schedule 40 dimensions and provides a continuous-weld construction for those media types. It will not suit systems that require a different schedule rating, a female-threaded end or a non-galvanised finish. Projects demanding higher pressure ratings or alternative thread standards should look at other fittings.

Behaviour under sustained pressure and temperature

The galvanised steel holds its 150 psi rating continuously at the stated temperature without burst degradation. The continuous weld resists fatigue from prolonged thermal cycling and vibration. Corrosion protection remains effective during extended exposure to the listed fluids, maintaining joint integrity over long service periods.

Questions about this item

Does this 3-inch MNPT close nipple need a female NPT fitting on the pipe I am connecting it to?

Yes, the male NPT threads require a matching female NPT fitting such as a coupling, valve or equipment port to make a sealed joint.

Can I join this Schedule 40 nipple directly to an existing Schedule 40 galvanized pipe of the same nominal size?

Yes, both have the same 3 1/2-inch outside diameter and NPT threads, so a standard coupling will connect them without adapters.

How can I verify the nipple is holding pressure after installation?

Pressurise the system up to 150 psi at 150 °F and check every joint for leaks; no weeping means the threads and weld are sound.
