UNSPSC 31311700: Bonded pipe assemblies

UNSPSC 31311700 Bonded pipe assemblies is a Class code covering the supply of industrial and infrastructure pipes, fittings, and related materials that state and local governments procure on an as-needed basis to support water, wastewater, stormwater, and airport operations. The recent opportunities show heavy activity in High-Density Polyethylene (HDPE) pipe, Polyvinyl Chloride (PVC) pipe, concrete pipe, ductile iron pipe, and fiberglass-reinforced materials, ranging from 0.75 inches to 66 inches in diameter, along with couplings, elbows, tees, flared ends, and ancillary fittings. State and local buyers include cities (Phoenix, Arlington, Palm Bay, Dallas, Augusta), counties (Colquitt County, Orange County, Pasco County, Santa Clara County, Clayton County), and special-purpose authorities (Phoenix Aviation Department serving three airports; Clayton County Water Authority). The City of Phoenix Public Works Department appears as a repeat buyer, posting two separate IFBs (IFB26SW0379 in August 2026 and IFB27SW0447 in September 2026) for the same scope, both seeking three-year supply contracts with two optional one-year extensions for HDPE and PVC pipe, fittings, and hand tools, with 24-to-48-hour delivery requirements and mandatory local inventory maintenance. Contracts emphasize firm, fixed pricing for multi-year terms, FOB destination delivery, and DBE participation or small-business subcontracting commitments where federal funding applies.

Recent solicitations span Arizona, Georgia, Florida, Texas, Utah, and California. The City of Phoenix (Arizona) is the most active issuer, with two concurrent industrial-pipe supply contracts. In Georgia, Colquitt County issued an IFB for concrete pipe with lift holes ranging from 15 to 66 inches (due October 14, 2026), the City of Augusta issued an ITB for HDPE pipe, couplings, and end sections for stormwater drainage (due September 29, 2026), and the Clayton County Water Authority issued a sole-source notice for $6.07 million in Fiberglass Reinforced Polymer Mortar pipe, 18 to 60 inches, from Hobas Pipe USA (due May 13, 2026). In Florida, the City of Palm Bay solicited bids for the I-95 Outfall Pipe Replacement project (due July 14, 2026) under an existing permit framework, and Orange County sought emergency bridge replacement bids including structural components (due July 7, 2026). The City of Dallas issued a five-year ID/IQ master agreement for ductile iron pipe supply to the Water Utilities department (due June 12, 2026). Many solicitations apply federal nondiscrimination statutes, E-Verify employment verification, and DBE or local-bidder preferences where threshold dollar amounts trigger set-asides under 49 CFR Part 26 or municipal ordinance.
