Blind end of oil transfer line
Thread Content
What is the purpose of having a blind end on the oil transfer line leading into the vacuum distillation tower, and why are some systems without it? Thank you, teacher
By blind end, does the poster mean a flanged blind end or a welded blind end? Can I get a picture?
Is it to reduce the erosion at the elbows?
Guess: it is used to facilitate the installation of pipe supports (spring supports that absorb pipe stress), or it can function as a support in itself, with both options being used in combination.
It seems that this can easily lead to dead ends, which is not good.
What is the spiral tube behind the third image used for? Why is it made in a spiral shape?
That’s the bracket; as for why a red piece is added, it’s not clear
There’s nothing that can be done about this – with 4 branches coming together and requiring an inclined connection to the main pipe, I can’t think of a way to install it without using a dead end.
