UNSPSC 31311306: Non metallic bolted pipe assemblies

UNSPSC 31311306 Non metallic bolted pipe assemblies (Commodity) encompasses the supply of non-metallic pipe products and associated fittings and appurtenances used in municipal water, sewer, and stormwater infrastructure projects. State and local government procurement under this code focuses on high-density polyethylene (HDPE), polyvinyl chloride (PVC), reinforced concrete pipe (RCP), and corrugated metal pipe in diameters ranging from under one inch to 90 inches, supplied as materials for new construction, replacement programs, and emergency repairs. Recent solicitations show municipalities and water authorities buying pipe inventory on as-needed and annual contract bases, with delivery windows of 24–48 hours for stock items and integration into broader infrastructure construction projects. Issuing bodies include city public works departments, water utilities, county water and sewer authorities, and special-purpose water districts across multiple states. Cities of Phoenix and Arlington, Barnwell County, Gwinnett County, Orange County, and regional authorities (Beaufort-Jasper Water & Sewer Authority, Notla Water Authority) all posted procurement activity under this code in the past three months, with repeat activity in Florida (Palm Bay, Orange County) and Georgia (Gwinnett County, Bryan County, multiple municipalities).

Geographic spread covers Florida, Georgia, South Carolina, Texas, Connecticut, California, and Massachusetts, with the heaviest recent concentration in Florida and Georgia. Representative recent opportunities include the City of Phoenix Public Works Department IFB 26SW0379 (posted July 8, 2026, due August 12, 2026) for supply of HDPE and PVC pipe ranging 0.75 to 24 inches in diameter plus miscellaneous fittings on a three-year as-needed contract with two one-year renewal options; Gwinnett County Board of Commissioners Invitation to Bid BL079-26 (posted April 16, 2026, due May 19, 2026) for annual stormwater pipe procurement spanning RCP, HDPE, and corrugated metal pipe products; and Beaufort-Jasper Water & Sewer Authority IFB 2026IFB025 (posted April 28, 2026, due May 27, 2026) for installation of approximately 1,950 linear feet of eight-inch and four-inch water mains and associated fittings on St. Helena Island, South Carolina. Procurement activity is steady and supports infrastructure replacement and capacity-expansion programs, with typical contract terms of one to four years and optional renewal periods at jurisdiction discretion.
