Summary of De-Icing Piping System Engineering Drawings

This document is a set of engineering drawings and technical specifications for a de-icing piping system designed for the NIST Neutron Research Facility. The drawings were prepared by CTS Engineering (Job No. 2228) and dated July 17, 2003, with revisions through November 2014.

The system includes three primary components: a de-icing piping layout for the facility's building envelope, a piping diagram and bill of materials for the east and west sides of the structure, and electrical wiring specifications for solenoid valves and track heaters. The piping layout details show multiple elevation changes ranging from approximately 5 feet to 14.5 feet, with specifications for rolling door motors, maintenance platforms, nozzle header mountings, and existing structural beam integration. The bill of materials identifies approximately 22 component types required, including CPVC and PVC piping (ranging from 1/2" to 1" diameter), various fittings, adapters, ball valves, spray nozzles, thermostats, and straps. The electrical wiring diagram specifies a 120/208 VAC panel installation with solenoid valve controls, thermostat settings adjustable to 35°F, and capillary tube installations running through the cooling tower structure. The system accommodates three separate doors with independent solenoid valve circuits and temperature control provisions for freeze protection in multiple locations.
