Piping
Remarks: The equivalent longest piping distance from the IDU to components of the first
branch pipe shall be no more than 40 m. However, when all the following conditions are met, it
is allowed to extend the length to 90 m. (in the case of "using TICA branch pipe".)
Required conditions Legends
1. The diameter of the pipe
between the components of
the first branch pipe and those
of the last branch pipe needs to
be increased. (Make the
variable diameter pipe on the
site); If the piping diameter is
the same with that of the main
pipe, it does not need to be
increased.
b + c + d + e + f + g + p ≤ 90 m;
The piping diameters of b, c, d,
e, f, g need to be increased
The piping size shall be increased
as follows
Φ9.5→Φ12.7
Φ12.7→Φ15.9
Φ15.9→Φ19.1 Φ19.1→Φ22.2
Φ22.2→Φ25.4 Φ25.4→28.6
Φ28.6→Φ31.8 Φ31.8→Φ34.9
Φ34.9→Φ38.1
2. When calculating the total
extension length, the actual
length of the preceding pipes
must be doubled. (except for
main pipe and pipes without
increased pipe diameter.)
a + b x 2 + c x 2 + d x 2 + e x 2 +
f x 2 + g x 2 + h + I + j + k + l + m
+ n + p ≤ 1000 m
3. Distance from the IDU to the
nearest branch pipe
component ≤ 40 m
h, i, j, l, m, n, p ≤ 40 m
4. Distance difference between
(the ODU to the farthest IDU)
and (the ODU to the nearest
IDU) ≤ 40 m
The farthest IDU 8
The nearest IDU 1
Farthest IDU-nearest IDU
