An extremely wide range of heat transfer conditions may exist on a liquid oxygen transfer line. Four major conditions are listed for comparison:
  1. 1)

    An uninsulated 4 inch diameter line with a heat transfer rate upwards of 600 BTU per linear foot per hour.

  2. 2)

    A 4 inch line coated with 1/8 inch frost and having a unit heat transfer rate of approximately 340 BTU per linear foot per hour.

  3. 3)

    A conventionally insulated 4 inch line having unit heat transfer rate ranging from 23 to 186 BTU per hour depending upon thickness and material used.

  4. 4)

    A vacuum or vacuum and powder insulated line with a unit heat transfer rate of 3 to 3–1/2 BTU per hour.
