Is it true that Plan 53B seal support system adopts air cooling heat dissipation and thermal siphon self-circulation operation mode?
 
Yes, this conclusion is completely correct.
 
The main reasons are summarized as follows:
 
1. Structural design: Plan 53B is fitted with air-cooled heat exchanger, it relies on natural wind for heat dissipation, no cooling water is required for operation.

2. Working principle: This system uses thermal siphon principle to drive internal barrier fluid automatic circulation, without additional driving pump.

3. Standard specification: API 682 clearly stipulates that Plan 53B is air-cooled self-circulation type seal auxiliary system, suitable for field sites without water supply conditions.
