FAQ

What work fits NAICS 332410?
  • Fabricate packaged steam boiler skid assemblies to engineering drawings, perform hydrostatic testing, and deliver ready-for-installation units to a project site.
  • Manufacture shell-and-tube or plate-type heat exchangers with specified metallurgy, pressure ratings, and post-weld heat treatment per drawing requirements.
  • Provide pressure-vessel fabrication including certified weld procedures, radiographic or ultrasonic NDT, and material traceability documentation.
  • Supply replacement economizer sections, boiler pressure parts, and welded assemblies with factory acceptance testing and shipping skids.
When is NAICS 332410 a weak fit?
  • On-site boiler erection and field assembly: scope centers on field installation, structural supports, and erection labor rather than shop-based fabrication activities.
  • Boiler rental or temporary steam service contracts: includes operation, maintenance, and temporary steam provisioning rather than manufacturing of permanent equipment.
  • HVAC equipment manufacturing: requests focused on commercial HVAC coils and fan systems lack the pressure-retaining fabrication, high-temperature design, and code stamping characteristic of power boiler manufacturing.
What solicitation language points to NAICS 332410?
  • Contract drawings include manufacturing tolerances, welding procedure specifications, weld maps, and bill-of-materials for shop fabrication.
  • Requirements call for ASME code stamping, material heat numbers, traceability documentation, and non-destructive testing records.
  • Line items specify factory acceptance testing, hydrostatic or pressure tests, post-weld heat treatment, and delivery of skid-mounted assemblies.
