Nozzle Orientation.

[Frank1344]

Folks,

I am under impression that Piping Design & Layout is resposible to determine it and Mechanical guys are implementing their positions inside the Mechanical drawing.

Is there any comment on this?

Kind Regards,

In my experience (more than 45 years) piping has done the vessel orientations (VO) at places like Fluor.

At Fluor, piping did all VOs because they have the broader view of the plant layout and the synergy of the process, the routing of the connected piping, operations, safety, construction/piping installation, etc.

However, it remains that some other company could have a different approach.

Don't buck the tide and don't offend the host.

It really depends on what you are buying. If its a standard piece of equipment or a complex piece of equipment that someone else is designing, you may not have a choice with the nozzle orientations. If you are specifying a tank from a fab shop (size, geometry, # and size of connections, etc.), the nozzle locations are typically a function of the process layout but may be limited on spacing and orientation by the piping loads.

Thank you all for the feedbacks.

Frank,

I am pretty sure a big company like WorleyParson (which also acquired Colt and Macdonald Engg in Canada) have work/project procedures, practices, and guidelines. I used to work with Parsons in the early 90's and they had some pretty good procedures and guidelines on vessel nozzle orientations.

Some orientations are set by the vessel internals - piping should be aware of this.
Some orientations are set by process requirements - should be on the equipment datasheet or P&ID - piping should be awre of this.
Some orientations are fixed due to "specialist equipment" as advised in the post above.
Piping advise all other orientations.
Vessels group check required orientations for code and project spec compliance.
If not acceptable piping need to re-arrange.
I find this a very strange question given the size of WorleyParsons now - I wonder what your clients would think of this question?

Again,
Thanks folks for the feedbacks.
