UNSPSC 40141763: Water hammer arrester

A type of device that is installed to prevent high noise and vibration due to the impact wave generated by the fluid inside the pipeline that moves the fluid.

UNSPSC 40141763 Water hammer arrester is a Commodity code that in recent state and local solicitations covers industrial pipe components, fittings, and water system accessories procured on supply and materials-only bases. The code shows broad activity across water infrastructure and utility supply contracts—jurisdictions are using it to tag procurements for industrial piping (HDPE and PVC in multiple diameters), ductile iron pipe nipples, sewer and stormwater pipes, fire hydrant assemblies, gate valves, and related appurtenances. The issuing body mix includes city public works departments (Phoenix, Palm Bay, Sarasota, Dallas, Calhoun), county utilities divisions (Orange County, Gwinnett County), and regional water authorities; Orange County, Florida appears as a repeat buyer, with separate solicitations posted for sewer pipes and fittings (five-year estimated spend of $28.7 million) and bridge replacement materials in the past four months. Cities are also using the code for emergency stormwater and outfall pipe replacement and water main relocation supply contracts.

Recent activity concentrates in Florida and Georgia. The City of Phoenix Public Works Department issued IFB 26SW0379 on July 8, 2026, soliciting industrial pipe, fittings, and equipment on an as-needed basis with a three-year term commencing December 1, 2026 and response due August 12, 2026; the City of Sarasota issued ITB 2631JS (response due June 16, 2026, now passed) for materials-only bids for small AC water main replacement pipe and fittings from an approved material list. Orange County, Florida posted Y26-126 for sewer pipes and fittings with an estimated five-year spend of $28.7 million and a Service Disabled Veteran Business preference; the City of Palm Bay posted ITB 41ITB26 on June 8, 2026, for I-95 outfall pipe replacement (bids due July 14, 2026) governed by Florida Department of Environmental Protection permits. The City of Calhoun, Georgia issued a sealed bid on May 20, 2026, for water main relocation materials including ductile iron mains, PVC piping, and gate valves (bids due June 18, 2026). Gwinnett County issued an informal written quotation for ductile iron pipe nipples with PE coating (quotes due April 23, 2026). Opportunities are driven by aging water and stormwater infrastructure replacement, emergency repairs, and utility system upgrades under federal and state environmental permits.
