UNSPSC 20121454: Perforated and slotted tubing liner and spacer

Liner is a casing string that does not extend back to the wellhead, but is hung from another casing string. Liners are used instead of full casing strings to: Reduce cost. Improve hydraulic performance when drilling deeper. Allow the use of larger tubing above the liner top.

UNSPSC 20121454 Perforated and slotted tubing liner and spacer (Commodity) shows minimal relevance to recent state and local solicitations tagged under this code. The two most recent opportunities—gas extraction and refrigerant recovery services from the City of Tucson, and law enforcement equipment procurement through a Minnesota cooperative purchasing vehicle—do not align with the code's nominal scope of specialized tubing products. The City of Tucson RFP No. 240011 seeks EPA-certified refrigerant reclaimers to extract and document gases from appliances at the Los Reales Sustainability Campus on a bi-weekly schedule, with pricing structured around Freon removal, mixed gas extraction, and labor rates for general, after-hours, and holiday service windows. The Sourcewell RFP No. 061626 establishes a cooperative contracting vehicle for law enforcement equipment available to participating Washington state counties and broader public entities across the United States and Canada. Neither opportunity involves procurement of tubing liners or spacers as traditionally understood under this commodity code.

Geographic activity is concentrated in the Southwest (Arizona) and Pacific Northwest (Washington), with the City of Tucson in Pima County representing the only directly relevant recent procurement and Sourcewell serving as a Minnesota-based cooperative purchasing platform. The code shows limited recent state and local activity aligned with its product definition, and the opportunities present in the dataset appear to reflect misclassification or broader equipment categories rather than demand for perforated and slotted tubing liners and spacers. Firms pursuing this code should verify actual buy patterns through direct jurisdiction research rather than relying on recent tagged opportunities to characterize market activity.
