Attachment (A)_Specifications_1500 Gallon Pure Water Tank FY26 for Solicitation.pdf

This document is a detailed technical specification for the procurement of a 1500-gallon pure water tank assembly for federal contracting purposes. The specification requires a stainless steel (Grade 316) horizontally oriented cylindrical tank with elliptical/flanged and dished end caps, complete with an integrated saddle assembly featuring lift lugs and fork lift tubes. The tank must be designed and fabricated in accordance with ASME Boiler and Pressure Vessel Code Section VIII Division 1, with formal Norfolk Naval Shipyard (NNSY) approval required prior to fabrication. Key operational specifications include a design pressure of 30 psig, vacuum design of 29 inches Hg, normal operating pressure of 20 psig, and design temperature range of -20°F to 120°F Fahrenheit. The tank must fit within a standard 20-foot ISO intermodal container with dimensions not exceeding 90 inches width and 89 inches height.

The specification mandates comprehensive monitoring equipment including a Temposonics/MTS liquid level sensor transmitter with resistance temperature detector, a Precision Digital process meter for volume display, and a compound pressure gauge with digital display. Multiple piping assemblies are required including drain/suction lines with vortex breaks (1½-inch SCH 40), sample line (3/8-inch), fill line (2-inch), relief valve discharge line (1-inch), nitrogen supply line (1-inch), and vent assembly (2-inch) with 75-micron stainless steel screen. All components must be stainless steel (Grade 316) with full-port ball valves (Swagelok 60 series or Bray 7000/8000), seamless piping per ASTM A312, and butt-weld stainless steel fittings. The vendor must conduct comprehensive testing including hydrostatic pressure testing to 33±2/-0 psig, level calibration to 90% capacity, magnetic particle and liquid penetrant inspections of lift lugs, load testing at 150% of service load, and drop-weight or Charpy impact testing. All deliverables must include detailed certifications, test reports, tank assembly drawings with material lists, rigging diagrams, and operating manuals for all monitoring equipment.
