Set-up of Delivery Pipeline
Pipeline identification
Delivery pipeline can be identified in three separate
categories: baseline, vertical run, and horizontal run. A
fourth, and very important component of the pipeline, is
the thrust block.

The baseline is the horizontal section
that runs from the pump to the elbow
that turns the pipeline vertical. A
standard rule of thumb when pump-
ing a high-rise is: for every 10 feet of
vertical run, the pump should be set
back 1 foot from the base of the ver-
tical run. For example: If the vertical
run is 200 feet, the pump should be
set back 20 feet from the base of the
vertical run. The baseline is the sec-
tion of delivery line that will require
the thickest pipe wall, because it is
the closest to the pump. All sections
of the baseline should be connected
by two-bolt clamps), and the pipeline
should be anchored solidly.

Vertical run
The vertical run is the section that goes from the thrust
block vertically to the top of the structure. It is very im-
portant to secure the vertical run in such a way to pre-
vent sideways movement of the line during the pumping
operation. It is recommended that two bolt clamps be
used to attach the pipes to each other and at least one
anchor clamp be used every ten feet of the vertical run
to secure the pipeline to the building. (Figure 32) shows
some pipe support options.

Horizontal run
The horizontal run is that section of pipeline that begins
with the elbow on top of the vertical run and ends at
the point of delivery. When possible, the horizontal run
should be slickline (steel pipe) with only enough rubber
hose to allow the required flexibility for ease of place -
ment.
