3 in Schedule 40 Steel Pipe Nipple

This 3 inch Schedule 40 black anodized steel pipe nipple is manufactured in the USA for industrial piping systems. It connects threaded components in air, gas, non-potable water and oil lines. The welded Grade B steel construction provides structural integrity for permanent installations. Model 330046004 suits maintenance crews and facility engineers specifying standard iron pipe size fittings.

Pressure and Temperature Ratings

The nipple withstands a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. It handles saturated steam up to 150 psi at 360 degrees Fahrenheit. These limits define the safe envelope for continuous service in mechanical rooms and process piping. Verify system design conditions against these ratings before installation.

Sustained Service Behavior

Under continuous pressure the welded seam maintains seal integrity without the fatigue risk of threaded joints. The black anodized coating resists surface corrosion during long exposure to moisture and oil vapors. Material creep remains negligible within the rated temperature range. The fitting does not carry a minimum temperature rating, so sub-zero environments require separate engineering review.
