3/4" Carbon Steel Pipe Nipple

This 18 inch threaded pipe nipple connects fittings in air gas and potable water systems. It is built from galvanized carbon steel grade B for corrosion resistance. The welded construction meets class 150 fitting compatibility for standard plumbing installations.

Sustained Pressure And Temperature Performance

The nipple handles a maximum operating pressure of 1454 psi at 650 degrees Fahrenheit. It maintains this rating for steam service at the same pressure and temperature. The minimum operating temperature extends to minus 20 degrees Fahrenheit for cold environment use.

Upgrade From Lower Schedule Or Uncoated Pipe

This schedule 40 wall thickness replaces thinner wall nipples when higher pressure containment is required. The galvanized coating replaces bare steel where moisture exposure causes rust. The grade B steel upgrades from lower grade material for improved structural integrity.

Questions about this item

Will the 1454 psi maximum operating pressure at 650 Degrees F generate noticeable heat or noise during continuous all-day use?

No, the carbon steel nipple has no moving parts and produces no noise or heat itself; it simply contains the fluid at the rated pressure and temperature.

What mating fittings must I already have to install this 3/4 in MNPT threaded nipple?

You need female NPT fittings rated for Class 150 service that match the 3/4 in nominal pipe size and can handle up to 1454 psi at 650 Degrees F.

Can this Sch 40 nipple stay in line with older galvanized piping that has a smaller inside diameter?

Yes, the 53/64 in inside diameter matches standard Sch 40 dimensions, so it connects directly to existing 3/4 in galvanized pipe of the same schedule.
