45° Elbow 3/8 in FNPT 2000 psi

This malleable iron pipe fitting connects two female NPT threads at a forty-five degree angle. It is rated for two thousand psi at one hundred fifty degrees Fahrenheit and three hundred psi saturated steam at five hundred fifty degrees Fahrenheit. The operating range spans minus twenty to five hundred fifty degrees Fahrenheit. It meets ASME B16.3 and carries AAR, FM and UL approvals.

Class 300 schedule and certifications

The Class 300 schedule provides the wall thickness required for the stated pressure ratings. AAR and FM approvals indicate suitability for railroad and fire-protection systems respectively. UL listing confirms compliance with applicable safety standards. These certifications allow the fitting to be specified in regulated piping installations.

Temperature and pressure limits

Maximum pressure drops as temperature rises above one hundred fifty degrees Fahrenheit, reaching three hundred psi at five hundred fifty degrees Fahrenheit for saturated steam. The lower limit of minus twenty degrees Fahrenheit restricts use in extreme cold environments. Designers must verify that system conditions stay within these boundaries for the fitting to perform as rated.

Questions about this item

Will the malleable-iron threads need re-sealing or replacement after repeated assembly?

The Class 300 malleable-iron FNPT threads are rated for 2000 psi at 150 °F and 300 psi saturated steam at 550 °F; inspect sealant each time the joint is broken and replace if deformation appears.

What pressure or temperature limit will be reached first in continuous steam service?

Saturated steam pressure is limited to 300 psi at 550 °F, which is lower than the 2000 psi water rating, so the steam limit governs sustained high-temperature use.

How hot does the fitting body get when carrying 300 psi steam all day?

The fitting operates up to 550 °F under 300 psi saturated steam; surface temperature will approach the fluid temperature, so insulation is recommended for personnel protection.
