About this file
This document is a Scope of Work for a Propulsion Systems Laboratory (PSL) Primary Cooler Replacement Hatch for NASA Glenn. The scope requires a like-for-like replacement of an existing hatch due to previous leaks and an upcoming hydrostatic test. Specific technical requirements include a 28 CL150 Horizontal "Tube Turns" Double Bolt Closure, bored 27.25" x .375" wall, with design pressure of 50 psig and design temperature of 250 Deg F. The hatch must be constructed with specific material specifications: hub material SA350LF2 CL1/A694-F46, head material SA 516N Gr. 70, and external components in carbon steel, with a gear operation and Buna O-Ring installation.
The procurement has a strict delivery deadline of December 15th, 2025, to NASA Glenn's PSL. Deliverables include the 28" CL150 Hatch as specified 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 hatch must meet specific technical parameters, including a minimum design temperature of -20 Deg F and be suitable for the existing installation position with minimal modifications.

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)
