TJ-524-001 Sea Chest Cross-Over Piping.pdf

This document is a technical drawing specification sheet for a Sea Chest Cross-Over Piping assembly for the National Oceanographic and Atmospheric Administration (NOAA). The drawing is designated TJ-524-001 and includes detailed mechanical schematics, parts lists, general notes, and references for manufacturing and installation requirements.

The parts list specifies multiple components including valve battery line type assemblies, weight trim weights, and various piping configurations with specific dimensions and material specifications. General notes establish that all piping materials and workmanship must comply with applicable federal regulations and standards; the system must be hydrostatically tested at 150 percent of maximum working pressure; piping shall be painted per reference 3; and pipe support hangers must be installed using clamp size and maximum span specifications per reference 1. The drawing includes two detailed plan views (Section 14-B and Plan 9-B) showing the spatial layout, dimensions, and interconnections of the piping system with scales of 3/8" = 1'-0" and 1/2" = 1'-0" respectively. References cited include various ASME, ASTM, and military specifications covering structural assembly details, machining, shielding, diesel engine cooling systems, and sea chest details. The document contains revision tracking indicating design approval and modification history.
