About this file
This Scope of Work document outlines requirements for a replacement hatch needed at NASA Glenn's Propulsion Systems Laboratory (PSL) Primary Cooler. The document specifies the procurement of a 30" CL150 Horizontal "Tube Turns" Double Bolt Closure hatch with specific technical requirements including: 29.25" x .375" wall bore, 50 psig design pressure, 250°F design temperature, -20°F MDMT, SA350LF2 CL1/A694-F46 hub material, SA 516N Gr. 70 head material, and CS externals.
The deliverables include both the physical hatch and comprehensive documentation (drawings with parts lists, operations manuals, maintenance manuals, and ASME Section VIII Division I U-Stamp with U2A Partial Data Reports). The replacement is needed due to leaks in the existing hatch and an upcoming hydrostatic test of the Primary Cooler water jacket. The procurement must be delivered to NASA Glenn PSL no later than February 15th, 2025, and requires a like-for-like replacement to ensure minimal modification to existing hardware.

Scope of Work
Propulsion Systems Laboratory (PSL) Primary Cooler Replacement Hatch
Background
The PSL Cooling primary cooler hatch has experienced leaks in the recent past. Due to an upcoming hydrostatic test of the Primary Cooler water jacket, the hatch must hold full test pressure. As a result, a like-for-like replacement of the existing hatch with new hardware is required. A like-for-like replacement ensures that the component may be installed in the same position as current with no or minimal modification to existing hardware.
Specification
The required hatch is the following:
30 CL150 Horizontal “Tube Turns” Double Bolt Closure Bored 29.25" X .375" Wall.
Design Pressure = 50 psig. Design Temperature = 250 Deg F.
MDMT = -20 Deg F.
CA 0
Hub Material SA350LF2 CL1/A694-F46 Head Material SA 516N Gr. 70 Externals CS
Period of Performance
Programmatic schedules and required installation time dictate that this procurement must be delivered to NASA Glenn, PSL no later thank Feb. 15th 2025.
Deliverables
1. 30” CL150 Hatch, as specified.
2. Paper and electronic copies of all hatch documentation. Including, but not limited to: drawings w/parts list, operations manuals, and maintenance manuals. As well as: ASME Section VIII, Division I U-Stamp with U2A Partial
