Pipe connections to the pelletizer. The following actions have been taken:
• Pos. 4 in the drawing, the supply pipe from the CO
2
tank has been connected to the ¾”
BSP nipple on top of the pelletizer in compliance with the specifications below.
• A degassing pipe pos. 3 in the drawing, has been connected to the 2” RG inch nipple on
top of the pelletizer in compliance with the specifications below.
Insulation of the supply pipe from the CO
2
tank in order to prevent unnecessary evaporation
of liquid CO

.
The following supply pipe specifications are observed:
• Internal dia. 20 mm (0.8 inch) for supply pipes up to 20 m (65.6 feet) in length.
• Internal dia. 25 mm (1 inch) for supply pipes greater than 20 m (65.6 feet) in length.
• A supply pipe temperature of -30
o
C (-22°F) and a supply pipe pressure of 40 bar (580
psi).
• Installation of the supply pipe onto the ¾” BSP nipple connection on top of the pelletizer
.
The supply pipe is installed so as to be protected from being damaged by vehicles, etc.
The supply pipe is installed so as to minimize the risk of gas pockets.
IMPORTANT!! Should physical circumstances make such secure installation impossible, the
piping and the whole pipe layout must be discussed with IceTech, and an additional gas
discharger may have to be installed.
A pipe or hose with an internal diameter of 2 ½” inches is installed to facilitate degassing
from the pelletizer into the open. The following specifications are observed:
• The type of material chosen for the degassing pipe is suitable for a temperature of -60°C
(-76°F) and for a pressure of 1 bar (14.5 psi).
• The degassing pipe is installed onto a 2” RG inch nipple on top of the pelletizer (as
shown on the drawing).
• Outdoor installations are performed so as to prevent rainwater from entering the degas-
sing pipe.
