FAQ

What work fits NAICS 333414?
  • Fabricate and deliver packaged steam boilers and burner-mounted assemblies to meet specified heat output and material requirements.
  • Manufacture welded heat exchangers and tube bundles to drawing-controlled dimensions with required material certifications and pressure testing.
  • Produce replacement spare components and assemblies for existing boiler plants, supplied with dimensional inspection reports and traceable material certificates.
  • Provide contract manufacturing of pressure vessels and skidded thermal systems including weld procedures, nondestructive testing, and hydrostatic or pneumatic testing records.
When is NAICS 333414 a weak fit?
  • HVAC installation and maintenance: field installation, ductwork connections, and ongoing service contracts are site service activities outside factory manufacturing scope.
  • Warm-air furnace manufacturing: production of warm-air furnaces is a different manufacturing classification excluded from this heating equipment category.
  • Commercial air-conditioning system manufacturing: large cooling equipment manufacture focuses on refrigeration and HVAC cooling cycles rather than heating equipment fabrication.
What solicitation language points to NAICS 333414?
  • Specification sheets and CLINs requiring ASME code stamping, weld procedure specifications, and mill test reports for pressure-retaining components.
  • Drawing-controlled fabrication deliverables with required nondestructive examination reports, hydrostatic test records, and material traceability documentation.
  • Deliverables listing factory acceptance tests, heat output performance curves, and spare parts kits manufactured to part numbers and revision-controlled drawings.
