UNSPSC 41113116: Gas detector tubes

UNSPSC 41113116 Gas detector tubes (Commodity) covers detection and monitoring equipment for hazardous gases in industrial and municipal facilities, though recent state and local solicitations show the code being applied primarily to systems-level gas detection infrastructure—including detector units, control panels, networking equipment, and integration with facility management systems—rather than individual detector tubes themselves. State and local buyers under this code include water and wastewater authorities managing treatment facility safety systems and state resource agencies overseeing industrial operations. The Great Lakes Water Authority (GLWA) in Michigan and the Texas General Land Office represent the issuing bodies in recent activity, reflecting a mix of utility operators and state resource departments.

The geographic spread of recent activity centers on Texas and Michigan. The Great Lakes Water Authority issued an RFQ in March 2026 for Primary Area Gas Detection System Upgrade and Switchgear Replacement at its Water Recovery Facility in Wayne County, Michigan, with responses due April 27, 2026, as a major systems integration project encompassing detector replacement across multiple facility zones, control panel installation, and Ovation system integration with fiber-optic networking and a provisional allowance of $425,000 for uncertain scope. The Texas General Land Office issued an RFQ in April 2026 for high hydrogen sulfide (H2S) well plugging and related services, with responses due May 5, 2026, seeking qualified contractors for workover and well maintenance on high H2S wells and requiring OSHA H2S certification and relevant safety training; this solicitation references multiple Texas cities including San Antonio, Fort Worth, Corpus Christi, and Lubbock. Both opportunities emphasize compliance with state-level set-asides and diversity certifications including Disadvantaged Business Enterprise, Minority Business Enterprise, and Small Business Enterprise designations.
