Regarding whether there are detachable splices on the inlet and outlet pipelines of the reactor in the diesel hydrogenation unit
Thread Content
As the title suggests, some reactors have detachable splices on their inlet and outlet pipelines, while others do not. I would like to ask those of you who have experience in this field: what is the difference between these?
High-temperature and high-pressure hydrogenation units generally do not use spools in order to reduce the number of sealing points. For example, our diesel refining process has bottlenecks, while diesel cracking does not.
In high-temperature and high-pressure applications, the number of sealing points should be reduced. So why do some design institutes include splices in their designs, while others do not? What is the purpose of including or not including such splices?
removable spool.
It’s probably because different design institutes have different design philosophies
