UNSPSC 40101859: Inline steam heater high pressure

Inline heaters make use of heating elements that are covered with a special type of vessel chamber that has anti-corrosion properties. This type of heating is indirect. The fluid is circulated through a closed loop around the heating element until it reaches the correct temperature.

UNSPSC 40101859 Inline steam heater high pressure is a Commodity code covering specialized heating equipment and related maintenance services. State and local procurement activity under this code centers on boiler and steam supply system maintenance, repair, and replacement work at public facilities — particularly housing authorities, transit agencies, and municipal buildings. The work typically involves inspection and restoration of steam risers, piping systems, valves, and fittings serving multi-unit residential or commercial buildings, often requiring certified technicians with access to proprietary parts and compliance with prevailing wage and Section 3 employment requirements when federal funding is involved.

Recent solicitations show activity concentrated in Pennsylvania and North Carolina. The Harrisburg Housing Authority posted an IFB for boiler steam supply line riser repairs at John A.F. Hall Manor Homes (due August 1, 2026), requiring replacement of failed steam risers across up to 24 building rows affecting approximately 240 units, with mandatory pre-bid site visits between June 22 and July 10, 2026, Davis-Bacon prevailing wage compliance, and HUD Section 3 benchmarks of 25 percent Section 3 labor hours or a 0.75 to 5 percent contribution to a Section 3 Training Fund. The City of Charlotte posted an RFP for preventative maintenance and repair services on boiler and chiller systems at CATS facilities (due October 15, 2026), requiring vendor certification to service Trane, Pulse, Aalon, Carrier, and Lochinvar equipment with access to proprietary parts and responsibility for maintenance, repair, optimization, and potential upgrades across Charlotte and Mecklenburg County locations. Housing authorities and municipal transit systems appear as repeat issuing bodies for this commodity. The code shows modest recent activity; the broader state and local market for steam system maintenance remains fragmented across individual facilities and jurisdictions rather than consolidated under region-wide contracts.
