1/2 inch Schedule 40 black steel pipe

This 1/2 inch nominal pipe is manufactured from Grade B steel with a welded construction and a black finish. It is designed for use with air, natural gas, non-potable water, oil, and steam applications. The pipe features male NPT threads on both ends for direct connection to Class 150 compatible fittings. It operates reliably across a temperature range of -20 to 600 degrees Fahrenheit.

Threaded ends and pressure rating

The 2 foot 6 inch length comes factory-threaded as TBE, eliminating the need for field threading during installation. A maximum operating pressure of 1715 psi at 650 degrees Fahrenheit provides substantial headroom for high-pressure steam or fluid lines. The 39/64 inch inside diameter ensures consistent flow characteristics for the specified media types. Class 150 fitting compatibility simplifies component selection for the installer.

Capacity for residential and light commercial runs

The Schedule 40 wall thickness handles standard distribution pressures for heating, compressed air, and fluid transfer systems. The 2.5 foot length suits short runs, risers, or connection drops between equipment and main lines. It is not suited for potable water service or gravity-flow drainage installations. Globally sourced steel construction meets the stated pressure and temperature limits for the listed applications.

Questions about this item

Will the black coating on this 1/2 in Sch 40 steel pipe wear off and need recoating?

The black finish protects the steel during storage and handling; it is not a corrosion barrier, so outdoor or damp installations will eventually require paint or a protective wrap.

What pressure limit is reached first when this pipe runs near its 600 °F temperature rating?

At 650 °F the maximum operating pressure is 1715 psi for both air and steam, so the pressure ceiling and temperature ceiling arrive together.

How hot does the pipe surface get when it carries steam at the rated 1715 psi all day?

Steam at 1715 psi reaches roughly 600 °F, so the pipe surface will approach that temperature and requires insulation or guarding to prevent burns.
