UNSPSC 73181205: Spin forming services

UNSPSC 73181205 Spin forming services is a Commodity code that covers the procurement of specialized water treatment equipment components, particularly flow controllers and associated valve assemblies custom-configured or precision-manufactured for potable water applications. State and local governments buy under this code engineered metal components for water treatment infrastructure — specifically precision-cast, pressure-rated flow measurement and regulation equipment built to exacting standards for municipal water systems. The issuing bodies are municipal water utilities and their procurement offices, which source these components through competitive sealed-bid processes when replacing aging or failed equipment at treatment plants.

The City of Lubbock, Texas Water Department is the primary recent buyer under this code, having issued ITB 26-19653-YB in May 2026 for a 16-inch venturi-type flow controller paired with an AWWA C504-compliant butterfly valve for the North Water Treatment Plant. The controller must deliver flow measurement accuracy within 0.5 percent over a 0-144 inches water column range, feature a cast iron body to ASTM A536 Grade 65-45-12 specifications with Type 316 stainless steel internals, and fit within a constrained 46.5-inch envelope. Lubbock accepted sealed bids through May 27, 2026, on an F.O.B. delivered basis with 60-day price firmness, held a non-mandatory site visit on May 20, 2026, and extended the contract through interlocal purchasing agreements to Frenship Independent School District, Lubbock County, Lubbock Independent School District, and Texas Tech University. Vendors must provide factory-assembled equipment, digital and printed O&M manuals, and meet Texas procurement certifications including suspension and debarment checks, Iran sanctions compliance, and cybersecurity disclosures. No budget or award value was published; the City applied a local bidder preference for contracts under $500,000 if the local bid fell within five percent of the lowest non-resident offer.
