3-1/2" Galvanized Steel Pipe Nipple

This 6-inch threaded pipe nipple connects air, gas, non-potable water or oil lines in industrial and commercial plumbing systems. It is built from welded Grade B steel with a galvanized coating for corrosion resistance. The component is manufactured in the USA and carries a nominal pipe size of 3-1/2 inches.

Schedule 40 Wall Thickness

The Schedule 40 rating provides a standard wall thickness that balances flow capacity with structural strength for moderate-pressure applications. This specification determines the inside diameter of 3 9/16 inches and an outside diameter of 4 inches. The welded construction ensures consistent integrity along the full 6-inch length.

150 PSI Pressure Rating

The nipple handles a maximum operating pressure of 150 psi at 150 degrees Fahrenheit, making it suitable for compressed air, inert gases and lubricant distribution. It is not rated for steam service or potable water systems. Builders requiring higher pressure ratings or steam compatibility must select a different class of fitting.

Questions about this item

How often will the galvanized coating on this 3-1/2 inch nipple need inspection or replacement?

The galvanized finish protects the Grade B steel from corrosion in air, gas, oil and non-potable water service; inspect threads and coating annually and replace if white rust or pitting appears.

What pressure or temperature limit will be reached first during continuous operation?

The fitting is rated for 150 psi at 150 °F; in sustained use the pressure ceiling of 150 psi is typically the first constraint encountered.

Does the nipple generate noise, heat or draw power when fluid flows through it all day?

As a passive welded steel nipple it has no moving parts, creates no heat of its own and consumes no power; any noise comes from fluid velocity in the piping system.
