Range G High Pressure Section Adapter Coupling Component - Collar Statement of Work

For Test Systems Sustainment Asset Management Branch, Arnold AFB, Tennessee

1.0 Background/Introduction. The Range G facility is in need of a coupling component to assemble barrel sections to each other. The collar is for use on Range G 3.3” Barrel Sections and High Pressure Section Adapter (Barrel) components. The collar provides an adjustable inner sleeve paired with each nut for securely coupling barrel sections together under high stress conditions.

2.0 Scope of Task. The contractor shall provide one (1) Collar manufactured per

VG113781-4 from vacuum processed alloy steel material per specification 900308/5.

Specifics for the material, heat treatment, quality conformance inspections, and all other fabrication details are included on the drawings and material forging specification. The completed coupling components are to be shipped to AEDC for inspection.
