UNSPSC 23153421: Twister or stranding machine

A machine that is used to manufacture rope, power cable, communication cable and the like by twisting the strands together to make a single stronger product.

UNSPSC 23153421 Twister or stranding machine is a Commodity code that in state and local procurement activity actually covers specialized water treatment equipment — specifically venturi-type flow controllers and butterfly valve assemblies used to regulate and measure potable water flow in municipal water treatment plants. The City of Lubbock, Texas, recently solicited a 16-inch venturi-type flow controller paired with an AWWA C504-compliant butterfly valve for its North Water Treatment Plant, requiring cast iron bodies with Type 316 stainless steel liners, NSF 61 approved epoxy coating, and factory testing to 0.5 percent accuracy. Equipment must fit within a maximum space of 46.5 inches and be compatible with existing electric valve actuators. This procurement shows a mismatch between the code's nominal scope (twisting or stranding machines) and the work actually being bought under it in state and local systems. Issuing bodies are city-level water utilities, though the source indicates that Lubbock's contract may extend to subordinate entities including Frenship Independent School District, Lubbock County, Lubbock Independent School District, and Texas Tech University through interlocal purchasing agreements.

The City of Lubbock, Texas, represents the only recent documented activity under this code. The City issued ITB 26-19653-YB with a response deadline of May 27, 2026, at 3:00 p.m., submitted through the Bonfire electronic portal or by hand delivery. Sealed bids were required on an F.O.B. delivered basis with firm pricing for a minimum of 60 days. A non-mandatory site visit was scheduled for May 20, 2026, at the North Water Treatment Plant. The City applied a local vendor preference for contracts under $500,000, allowing local bidders within city limits to win if their bid was within five percent of the lowest non-resident bid. Bidders were required to submit three project references from current customers of similar scope, a notarized non-collusion affidavit, conflict of interest disclosures, and vendor risk assessments addressing cybersecurity and personally identifiable information handling. No set-aside designations were noted, and no budget or award value was specified in the procurement documents.
