About this file
This document is a set of questions and answers related to a federal solicitation for the procurement of two mission-critical virgin hydrofluorocarbon (HFC) compressed gases, Heptafluoropropane (HFC227ea) and Hexafluoropropane (HFCR236fa). The solicitation, SPE4A2-24-R-0015, is being issued by the Defense Logistics Agency (DLA) Aviation. The gases will be placed in static storage at DLA Richmond, Virginia to ensure a sustainable supply for the Department of Defense's needs, which are projected to extend beyond 2060. The key details include the legal maximum fill weight and the operational difficulty of precise filling, for which DLA-AV has provided guidance on the acceptable target fill weight. The solicitation was posted on 8/1/2024, with offers due on 8/30/2024, and an amendment was posted on 8/21/2024 providing an updated summary of questions and answers as of 8/23/2024.

Question #28: As the legal maximum fill weight may be very close to the cylinder’s rated capacity, and considering the real-world operational difficulty of filling to a precise poundage 100% of the time, would it be acceptable to DLA-AV if A-Gas fills the cylinders to a target weight somewhat under (~5 lb or so?) the rated capacity?
Answer:
49 CFR 173.301(a)(8):
The pressure of the hazardous material at 55 °C (131 °F) may not exceed 5⁄4 of the service pressure of the cylinder. Su icient outage must be provided so the cylinder will not be liquid full at 55 °C (131 °F).
Specific to the 150lb and 1200lb cylinder see below
