About this file
This Scope of Work document details a replacement hatch procurement for NASA Glenn's Propulsion Systems Laboratory (PSL) Primary Cooler. The required hatch is a 28 CL150 Horizontal "Tube Turns" Double Bolt Closure with specific technical specifications, including a design pressure of 50 psig, design temperature of 250 Deg F, and MDMT of -20 Deg F. Key material requirements include hub material SA350LF2 CL1/A694-F46, head material SA 516N Gr. 70, carbon steel externals, gear operation, and a Buna O-Ring.
Deliverables include the 28" CL150 Hatch and comprehensive documentation such as drawings with parts lists, operations manuals, maintenance manuals, and ASME Section VIII, Division I U-Stamp with U2A Partial Data Report(s). The procurement has a strict delivery deadline of December 15th, 2025, with the hatch to be delivered to NASA Glenn's PSL. The procurement is driven by previous hatch leaks and the need for a like-for-like replacement to support an upcoming hydrostatic test of the Primary Cooler water jacket.

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:
28 CL150 Horizontal “Tube Turns” Double Bolt Closure Bored 27.25" 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 Gear Operated Buna O-Ring Installed
Period of Performance
Programmatic schedules and required installation time dictate that this procurement must be delivered to NASA Glenn, PSL no later than Dec. 15th 2025.
Deliverables
1. 28” 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
Data Report(s)
