The flash gas in the liquid line is also caused by changes in pipe elevation. When a high pressure liquid line is installed to run vertically upwards the change in elevation reduces the liquid pressure due to static head penalties. This can be compounded installing a liquid line that is too small in diameter. This causes an increase in friction loss due to flow.
So... it is necessary to insulate a properly sized high pressure liquid line.
If you ever hear someone saying a 3/4" liquid line is sufficient for any reason you should ask them: based on what? And see what their answer is.
There are reason for why things work. Unfortunately, these are also the same reasons why things don't work.If all else fails, ask for help.
