When blending into 50 lt cylinders I often find the mix does a stratification. Even after 7 days I do not measure what I expect, the gas is closer to the last topping gas, it does not perfectly mix. When laying down the cylinder for 24 hrs I get the perfect mix, no stratification anymore. But the 50 lt cylinder is hard to handle.
Now I was told I shall use a very long dip tube on the valve. 50 lt cylinders normaly have no dip tube at all, they do not need so because they are always stored upside. So I shall fix a dip tube of about 20cm/8 inch on the valve, going into cylinder. After blending I shall open the valve for a short time. This is said to create a turbulence inside the cylinder, IF there is a long dip tube. Without dip tube I get no turbulence. That's the theory. I dit fix such a dip tube and started blending. Result:
Test No. 1:
Cylinder A, no dip tube, perfect mix, no stratification. This happens sometimes,
Cylinder B, long dip tube, perfect mix, no stratification. Was it because of dip tube or not?
Test No. 1 is worthless.
Test No. 2:
Cylinder A, no dip tube, heavy stratification.
Cylinder B, long dip tube, no stratification.
Cylinder C, no dip tube, heavy stratification.
I layed down cylinder A and C for 24 hours, stratification was gone, perfect mix.
So it might have been the effect of long dip tube or just luck.
Before I take off all the valves on my 50 lt cylinder and add long dip tubes I ask you about your experiences. Does anyone use longer dip tubes and does the procedure of a short valve opening?
