UNSPSC 40171900: Pipe backup flanges

UNSPSC 40171900 Pipe backup flanges, a Class code, encompasses mechanical joint restraining devices, flanged fittings, and related pipe connection components that state and local water utilities and infrastructure departments purchase to support water distribution system construction, repair, and maintenance. The code captures both specialized mechanical restraint devices for ductile iron pipe (DIP) and polyvinyl chloride (PVC) applications and standard flanged fittings in cast iron and other materials used across water service operations. Recent solicitations show that issuing bodies under this code include county water and utility departments (Palm Beach County), city utilities (Phoenix Water Services, City of Tampa), and county transportation authorities (Santa Clara County); purchases range from discrete quantities of specialty fittings for specific projects to term contracts covering multiple product groups with hundreds or thousands of units across varied sizes and configurations.

Activity under the code concentrates in California and Florida, with recent high-visibility solicitations from Santa Clara County (pavement rehabilitation project including inductive traffic loops and related infrastructure, IFB posted April 29, 2026, due May 21, 2026), Palm Beach County (mechanical joint restraining devices for DIP and PVC on a term contract basis with an anticipated value of $200,000 over twelve months, IFB posted April 22, 2026, due June 4, 2026), City of Phoenix Water Services (water pipe and miscellaneous fittings including flanges for a five-year contract commencing May 1, 2026, IFB posted February 23, 2026, due February 19, 2026), and City of Tampa Purchasing Department (Standard Class 125 flanged fittings, RFQ posted March 9, 2026, due February 25, 2026). Palm Beach County's IFB explicitly offers small business enterprise price preference (ten percent if within ten percent of the lowest non-SBE bid) and local preference (five percent for bidders with permanent place of business in Palm Beach County or the Glades), while the City of Phoenix contract includes DBE compliance requirements under 49 C.F.R. Part 26. Suppliers responding to these solicitations face firm pricing requirements, standard insurance minimums ranging from $500,000 to $2 million depending on the issuing body, and delivery commitments typically within ten to thirty days.
