FO Purifier T-ALT Valve material List.png

This is a List of Material for a ship specification document that details components required for a single vessel. The material list includes nine items across piping and valve systems, with quantities ranging from one to two units per component. Key items specified include 1¼" and 2" socket weld tees rated at 3,000 LBS, a 2" x 1¼" reducing coupling, a 1¼" socket weld pipe, a 2" 50 pipe, and two globe valves (1¼" rated at 3,000 LB and 2" rated at 3,000 LB). All materials are fabricated from forged or carbon steel manufactured by WAO, with specifications conforming to ASTM A105 and ASTM A106 standards. Unit weights for individual components range from 1.6 LBS to 8 LBS, with total weights per item ranging from 1.6 LBS to 10.0 LBS.

The document employs standardized abbreviations for technical parameters and ship system specifications, including centerline, diameter, existing equipment references, government-furnished equipment, general technical requirements, and installation activity furnished. Line types are indicated to denote ship centerline, existing equipment, and fuel transfer pipe runs. A removal table is referenced in a supplementary document (11-F), and the list is part of a larger system design data specification for naval vessel construction or modification.
