UNSPSC 31311613: Brass sonic welded pipe assemblies

UNSPSC 31311613 Brass sonic welded pipe assemblies (Commodity) shows minimal recent state and local procurement activity aligned with the code's nominal scope. The recent opportunities posted under this code predominantly solicit for High-Density Polyethylene (HDPE) pipe, Polyvinyl Chloride (PVC) pipe, copper tubing, and stormwater infrastructure replacement—materials and applications that do not correspond to brass sonic welded assemblies. The City of Phoenix Public Works Department has posted two identical industrial pipe and fittings solicitations (IFB 27-SW-0447 in September 2026 and IFB 26-SW-0379 in August 2026) requesting HDPE pipe ranging from 1.5 to 24 inches in diameter, PVC pipe from 0.75 to 4 inches, and associated fittings and hand tools on an as-needed basis for Phoenix Aviation Department operations across three airports. The City of Augusta, Georgia issued ITB 27-116 (due September 29, 2026) for HDPE pipe, couplings, and end sections for down-drain installation. These opportunities reflect municipal and county infrastructure maintenance and construction activity rather than brass sonic welded assemblies work.

Geographic activity concentrates in Arizona, Georgia, California, Florida, and South Carolina, with Phoenix appearing as a repeat issuer. The source does not support recent activity specifically soliciting brass sonic welded pipe assemblies. The code classification appears misaligned with actual procurement substance in the available opportunities; vendors evaluating this code should verify whether state and local procurement offices continue using this taxonomy for materials significantly different from the code's stated commodity, or whether the recent mislabeling reflects a classification anomaly. The actual volume and frequency of legitimate brass sonic welded assemblies procurement under this code remains unclear from the available data.
