Fractionating Column System (Cold Box)

convection sieve plate tower, the entire fractionating tower equipment pipeline adopts argon arc welding,

the tower body and main pipeline in the cold box are made of high-strength aluminum alloy or stainless steel

to increase the strength , Reduce the torsion damage of the pipeline. The equipment brackets, pipes and

valve brackets in the cold box shall be made of stainless steel or aluminum alloy. The cold box is insulated

with pearl sand and slag wool to ensure that the loss of cold capacity is minimized. The cold box

structure guarantees the overall strength and the requirements of anti-seismic and wind resistance,

and guarantees the load-bearing capacity of the cold box. When the cold box is running, it is equipped with

airtight protection and safety devices. The main equipment in the cold box is equipped with electrostatic

grounding. The cold valve and pipeline in the cold box all connections are welded, and flange connections

are avoided.

box of the expander is set separately for easy maintenance.
