UNSPSC 31311709: Stainless steel bonded pipe assemblies

UNSPSC 31311709 Stainless steel bonded pipe assemblies is a Commodity code that captures industrial piping systems for water, drainage, and infrastructure applications, though recent state and local opportunities show a broader mix of materials than the code name alone suggests. State and local governments are procuring HDPE, PVC, and concrete pipe alongside ductile iron and fiberglass-reinforced polymer systems for water utilities, stormwater management, airport operations, and public works on as-needed bases. Issuing bodies include city public works and utilities departments, county purchasing and water authorities, and airport districts, with repeat solicitation activity from the City of Phoenix (two industrial pipe IFBs in August and September 2026) and the City of Palm Bay (stormwater and outfall pipe work). Purchase structures typically run one to five years with optional extensions, firm-fixed pricing, FOB destination delivery, and inventory and 24-to-48-hour fulfillment requirements for as-needed supply contracts.

Recent opportunities cluster in Florida, Georgia, Arizona, California, and Texas. The City of Phoenix issued IFB 27-SW-0447 (response due September 30, 2026) for three-year supply of HDPE and PVC pipe ranging 0.75 to 24 inches with two one-year extensions, subject to DBE-N compliance and small business participation plans under 49 CFR Part 26. Colquitt County, Georgia released a one-year concrete pipe bid (due October 14, 2026) for lift-hole and flared-end pipe from 15 to 66 inches per C3 specifications. The City of Augusta, Georgia posted ITB 27-116 (due September 29, 2026) for HDPE pipe, couplings, and end sections under Minority and Women Owned Business Enterprise requirements and local-bidder preference within ten percent or $10,000. The City of Dallas established a five-year ID/IQ master agreement for ductile iron pipe to the Water Utilities department (bids due June 12, 2026). The Clayton County Water Authority issued a sole source notice for $6.07 million in FRPM pipe from Hobas Pipe USA for sewer replacement (response deadline May 13, 2026). Geographic activity is most active in Florida (Palm Bay, Orange County, Dallas outfall work) and Georgia (Colquitt, Augusta, Clayton County), with Arizona (Phoenix airports) and Texas (Dallas, Arlington) also showing current demand.
