3-inch Malleable Iron 90° Elbow

This 3-inch malleable iron elbow provides a 90-degree change of direction in piping systems rated for Class 150 service. It meets ASME B 16.3 and B 16.4 standards along with ASTM A-197 and ASTM A47 material specifications. The fitting carries FM Approved and UL Listed marks for code compliance.

FNPT Threaded Connection

Female National Pipe Thread ends allow direct assembly to male-threaded pipe or nipples without welding or flanges. The malleable iron construction delivers the ductility needed for threading and the strength to withstand 300 psi at 150 °F. Saturated steam service is rated at 150 psi.

-20 °F to 366 °F Temperature Range

The wide operating window from -20 °F up to 366 °F determines suitability for chilled water, hot water and low-pressure steam lines. Systems that exceed 366 °F or require pressure ratings above Class 150 cannot use this fitting.

Questions about this item

Will the malleable iron elbow need replacement if the system pressure approaches the 300 psi limit at 150 degrees F?

The fitting is rated for 300 psi at 150 degrees F and 150 psi saturated steam; operating within those limits avoids premature replacement.

What temperature limit is reached first during continuous saturated steam service?

Saturated steam pressure is limited to 150 psi, which corresponds to the 366 degrees F upper temperature boundary for this Class 150 elbow.

Does the malleable iron material radiate noticeable heat when the line runs at 366 degrees F all day?

At the maximum 366 degrees F the iron body will become very hot to the touch, so insulation or guarding is advised for personnel safety.
