UNSPSC 40183114: Stainless steel instrumentation tubing

Instrumentation tubing is made from stainless steel, and connects to the tubing or tubes utilized to attach instruments to central piping, other machines, appliances, or plumbing equipment. Instrument tubing is usually used adjacent to these piping systems, pressure switches, valves, flow monitors, and permitting the combination of pressure gauges.

UNSPSC 40183114 Stainless steel instrumentation tubing, a Commodity code, sees limited direct recent activity in state and local procurement records; the code name does not align with the pipe, fittings, and valve inventory commonly solicited by water utilities, wastewater authorities, and public works departments. Recent opportunities tagged under or near this code span industrial and potable water pipe supply contracts—High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), ductile iron, and specialized sewer pipe including vitrified clay pipe (VCP) and SDR26 PVC—rather than stainless steel instrumentation tubing. City public works departments, county water and sanitation authorities, and special-purpose water districts issue the majority of these solicitations on as-needed annual or multiyear contract bases, typically three-year initial terms with optional one-year renewals. Representative recent opportunities include the City of Phoenix Public Works Department's IFB 27-SW-0447 for industrial pipe, miscellaneous fittings, and equipment (response due September 30, 2026), the City of Augusta, Georgia's ITB 27-116 for various HDPE pipe, coupling, and end sections (due September 29, 2026), and the Douglasville-Douglas County Water and Sewer Authority's IFB 327 for annual water and sewer pipe fittings and related inventory materials (due October 7, 2026). All three solicitations emphasize firm-fixed pricing for one to three years, local inventory maintenance, fast delivery (24 to 48 hours in Phoenix's case, 60 days in Augusta and Douglasville), and DBE or MBE/WBE participation requirements.

Geographic activity centers on Arizona and Georgia, with additional recent procurements in California (Santa Clara County Sanitation District No. 2-3 structural defect repair, due September 17, 2026, for sewer mainline pipe bursting and replacement with HDPE and PVC), Florida (City of Palm Bay I-95 Outfall Pipe Replacement, due July 14, 2026, and City of Sarasota Small AC Water Main Replacement materials, due June 16, 2026), and North Carolina (City of Calhoun water main relocation supplies, due June 18, 2026). The code does not appear to drive procurement under its nominal stainless steel instrumentation tubing description; vendors pursuing this taxonomy should verify that opportunities are actually soliciting stainless steel tubing rather than standard potable or wastewater pipe inventory, as the recent record shows a consistent mismatch between the code name and the materials state and local water and wastewater systems are actively buying.
