3/4" Schedule 40 Black Steel Pipe

This 3 ft threaded black steel pipe carries air, natural gas, non-potable water, oil and steam. Welded Grade B steel construction handles up to 1454 psi at 650 °F and operates down to -20 °F. The 13/16 in inside diameter suits standard Class 150 fittings.

Builders needing 3 ft threaded pipe

Buyers who require longer runs or different nominal sizes should select another length. Installers needing potable-water approval or gravity-flow rating must choose a different product. The welded seam and black coating limit use to compatible fluid types.

1454 psi at 650 °F pressure rating

This maximum steam and operating pressure decides whether the pipe matches the system design. Verify that the service temperature and fluid type fall within the -20 °F to 600 °F range and the 1454 psi limit before installation.

Questions about this item

Will the Schedule 40 wall thickness need replacement sooner than heavier pipe under 1454 psi steam?

Schedule 40 steel rated for 1454 psi at 650 °F meets the same pressure class as heavier walls; corrosion or erosion from the fluid decides service life, not the schedule number alone.

Does the 13/16 in inside diameter become the flow bottleneck before the 1454 psi pressure limit?

At 13/16 in bore the pipe passes the volume its fittings allow; pressure drop across the 3 ft length stays minimal, so the 1454 psi rating is reached before the bore restricts flow.

How hot does the black steel surface get when carrying 600 °F steam continuously?

The pipe wall reaches near the 600 °F steam temperature; the black coating radiates heat but offers no insulation, so surface temperature equals fluid temperature under sustained operation.
