UNSPSC 40174200: Pipe sockolets

A fitting used for socket welding branch connection, which requires a reinforcing pad.

UNSPSC 40174200 Pipe sockolets, a Class code, encompasses industrial and municipal pipe fittings and accessories that state and local water, sewer, and public works departments procure on an as-needed basis for infrastructure maintenance, replacement, and expansion. The code captures a broad range of piping products including HDPE and PVC pipe in multiple diameters, couplings, wyes, ells, tees, gate valves, tapping sleeves, quick insertion valves, and related appurtenances used in potable water systems, wastewater conveyance, stormwater drainage, and airport operations. Recent solicitations show state and local buyers procuring these materials as inventory stock for routine operations rather than as components within larger construction projects.

Issuing bodies span water utilities, cities, counties, and special-purpose districts across the Sun Belt and mid-Atlantic regions. The City of Phoenix Public Works Department and the Phoenix Aviation Department appear as repeat buyers, posting two separate three-year supply agreements for industrial pipe and fittings (IFB 26-SW-0379 in August 2026 and IFB 27-SW-0447 in September 2026) serving three airports and general municipal operations. Georgia municipalities and water authorities dominate recent activity: the City of Augusta posted an ITB for HDPE pipe, couplings, and end sections (PE72155NONST2027000000214, due September 29, 2026); the Douglasville-Douglas County Water and Sewer Authority solicited annual pipe fittings and related inventory materials (IFB 327, due October 7, 2026); and DeKalb County issued a three-year multiyear contract for quick insertion valves (ITB 2026-034-ITB, due August 27, 2026). The City of Calhoun, Georgia posted a sealed bid for water main relocation materials including ductile iron mains and mechanical joint fittings (PE76500NONST2026000000020, due June 18, 2026). Activity extends to Florida and California: the City of Sarasota procured pipe and fittings for potable water main replacement per an approved materials list (ITB 26-31JS, bid deadline June 16, 2026—already closed); Santa Clara County Sanitation District No. 2-3 sought contractors for sewer mainline repairs and replacements involving PVC and HDPE pipe bursting (ITBRDAFY260694, due September 17, 2026); and the City of Palm Bay issued a materials-only RFI for stormwater pipe rehabilitation along the Malabar Road corridor (RFI 38RFI26, due June 9, 2026). Contract structures typically span one to three years with optional renewals, firm fixed pricing, as-needed ordering, delivery within 24–72 hours or 60 days depending on the buyer, and local inventory or fast-fulfillment requirements. DBE, MBE, and WBE participation goals and local-vendor preferences appear in several Georgia and Arizona procurements; E-Verify and prevailing wage compliance are common for federally assisted projects. The code shows sustained procurement activity driven by aging water and sewer infrastructure rehabilitation programs across mid-sized cities and utility districts.
