About this file

Written by GovTribe AI · Feb 9, 2026

This document is a set of technical engineering drawings and specifications for a Storm Surge Sensor Housing and related components developed for the United States Department of the Interior, Geological Survey - Water Resources Division.

The drawings detail specifications for multiple fabricated metal components including a storm surge sensor housing (main cylindrical assembly with flanged ends), V-block weldment (angular support structure), pipe weldment (longitudinal assembly with coupling), aluminum pipe, decal label, and an accessories parts kit. The storm surge sensor housing features a cylindrical design approximately 17 inches long with multiple mounting holes (32 pieces at 3/8-inch diameter and 3 pieces at 1/2-inch diameter), flanged end plates, and internal support structures. Critical specifications include dimensional tolerances in both inches and millimeters, surface finish requirements (63 microinches Ra), material callouts for aluminum and steel components, and detailed welding notes. The accessories kit includes component items such as plastic zip-lock bags (12.0 x 12.0 inches), washers, wire ties, bolts, masonry hex washers, and hose heaters, with suggested sources of supply identified including Gates Corporation (Denver, CO), Thomas & Betts Corp. (Memphis, TN), and McMaster-Carr Supply Co. (Atlanta, GA). All drawings are marked with revision controls, approval signatures, and drawing numbers ranging from 0662001 through 0662008, with metric conversion factors and standard engineering tolerances noted throughout the documentation package.
