UNSPSC 20121120: Bow spring centralizer

A type of centralizer employing a metal strip shaped like a hunting bow attached to the outside of well casing. Used to keep casing in the center of a wellbore prior to and during a cement job.

UNSPSC 20121120 Bow spring centralizer is a Commodity code, but the recent state and local opportunity tagged under it does not reflect equipment procurement — instead, the City of Tucson Environmental and General Services Division solicited refrigerant extraction and gas recovery services through RFP 240011. The code shows minimal relevant recent activity; state and local governments do not appear to be routinely purchasing bow spring centralizers or similar downhole completion equipment through these procurement channels at present.

The single opportunity on record is the Tucson gas extraction RFP, issued September 30, 2026, with a response deadline of September 19, 2024 (a historical date suggesting the record is outdated). The work sought an EPA-certified refrigerant reclaimer to extract gases from approximately 50 units per week at the Los Reales Sustainability Campus, with extraction required at minimum every two weeks. Evaluation focused on EPA compliance, technical capability, and documentation practices rather than equipment supply. The mismatch between the code's nominal scope (downhole well equipment) and the actual solicitation (environmental remediation services) indicates that either the tagging is erroneous or the code is not an accurate descriptor of state and local buying activity in this area. For firms focused on oil and gas completion equipment, this code presents no actionable recent opportunity signal.
