UNSPSC 40172604: Ductile iron pipe coupling

Pipe coupling made of ductile iron

UNSPSC 40172604 Ductile iron pipe coupling, a Commodity code, covers coupling and fitting products for water and sewer infrastructure projects. State and local governments procure these components as part of larger water main replacement, sewer rehabilitation, and pipeline rehabilitation programs. Recent solicitations show that couplings are commonly bundled with pipe materials, service connection fittings, and valve components in comprehensive infrastructure improvement contracts. Issuing bodies include county utility authorities, county sanitation districts, county public works departments, and municipalities. The work is solicited through IFB and ITB notices structured as either project-specific contracts with extended timelines or annual supply agreements with unit pricing.
