4.5.6 Calculation of the pipe length
(1) Available length of pipe =pipe the amounts of branch × branch equivalent length
+the amounts of elbow × elbow equivalent length.
(2) Conversion of the branch equivalent length: Convert into the direct pipe length according to
branch part 0.5m/l
(3) Conversion of elbow equivalent length.

4.6.1 Protection of Refrigerant pipe material
1) Transportation and storing of refrigerant pipe
When transporting the pipes, please protect the pipes from wending and distortion. Please
place a cap at the open end of the pipe in order to prevent water and mud entering, and store in
the appointed site.
3)
All the open tips of the pipes need to be protected. The best feasible means is Enveloping
End, and you can select the easy means of Wrapping. Refer to the following table to select
the means used in different sites.
