4-6 Installation of branch pipes
1)
The branch pipes should adopt U-type or Y-type ones, but never T-type ones.
2)
The branch pipe must be installed horizontally,with the deviation angle no greater than ±10°.
3)The branch pipe cannot turn directly when led out, and the straight length section cannot
be less than 0.8 meters.
4-7 Oil return bend settings
Note:When the vertical height is more than 10 meters,
it is necessary to add oil return bend in the middle.
Divide the vertical segments into sections not
larger than 8 meters.As shown in the picture:
High pressure liquid pipe
8m
Low pressure gas pipe
Oil return bend
16m
