UNSPSC 39131720: Running thread conduit

A length of pipe, usually steel, with thread over the length of the outside diameter OD used to enclose conductors.

UNSPSC 39131720 Running thread conduit is a Commodity code capturing the purchase of plastic conduit for utility and infrastructure applications — specifically Dura-Line and similar polyethylene products sized from 12 inches to 90 inches in diameter, sold in linear-foot quantities for stormwater, telecommunications, and highway projects. State and local governments procure under this code through transportation authorities, county boards of commissioners, and water resource departments, typically via competitive sealed bids (IFB) with four-day to month-long response windows and delivery requirements ranging from 14 days to several months post-award.

Recent activity clusters in Kansas, California, and Georgia. The Kansas Turnpike Authority issued an IFB on May 12, 2026 (due May 16, 2026) for 337,920 linear feet of 1-1/2-inch Dura-Line conduit in three color specifications (green, orange, and black/red), with pre-approval required for any non-listed manufacturers. Gwinnett County Board of Commissioners posted BL079-26 on April 16, 2026 (due May 19, 2026) for stormwater pipe on a four-year annual contract with four optional 12-month renewals, encompassing reinforced circular concrete pipe, high-density polyethylene, and corrugated metal pipe across multiple diameter ranges, delivery within 14 days of order, and contract commencement August 24, 2026. Santa Clara County's Central Expressway Pavement Rehabilitation Project (ITBRDAFY260694, posted April 29, 2026, due May 21, 2026) includes removal and replacement of inductive traffic loops and traffic signal modifications as part of broader pavement rehabilitation, though the primary scope centers on asphalt overlay and curb work rather than conduit itself. No set-asides, minority or disadvantaged-business preferences, or budget ranges are disclosed in the available solicitation abstracts.
