Heat Exchanger datasheet from NORSOK (RDS-019)

[Khaled.K]

I'm involved in a project where I'm supposed to understand all terms in the RDS-019 datasheet from NORSOK, that is for Shell & Tube Heat Exchangers. Can't complain so far, with the help of the internet and some discussions with CGPT, I managed so far, even with no experience to mention. Now I'm stuck with some attributes that I couldn't find anything helpful about.

These that are in line 70. Are all of these components related to sliding the bundle in the shell? Is it how it looks in this example, that you can only have one of them (they don't work together for a single purpose)? Simply, what are these? and how do they relate to each other? is "Sliding parts" an inclusive term for the other two?

I will highly appreciate any pictures that can help me understand what those are.

No, these are three separate but related items.
They relate to how the tube support plates or baffles are held together and in place.
Many heat exchanger producers have nice cutaway pictures on there websites.

Sorry that I forgot to mention that the tie rods are covered somewhere else in the datasheet, so I think the rods here are something different. That's actually a big part of the confusion.
I've seen a lot of pictures, but couldn't recognize what the parts in question are.

Thanks

Is this an old DS or standard.

I can't see this data sheet anywhere in the current Norsok catalogue.

Does it reference a specification or standard where these items might be explained?

Why not ask the client what is wanted?

It's in NORSOK mechanical equipment R-001, revision 1, 1994. This is the standard the project I'm working on adopted for datasheets.

Go directly to the source. It is more reliable than anything you might find on some forum.

 

[LittleInch]

Why are you using a standard that's 30 years old??

The newest one is 2017.

But really not sure if it's a good idea to fill out such a datasheet if you really don't know what you're doing.

Rod or bar type baffles are used to eliminate dead or stagnant flow zones on shellside - there is a description of these on page 11-42 in Perry Chem Engg Handbook 7th edn. Must confess I dont know how these look or work though.

I've never seen those terms before but my guess is that "Slip" might refer to skid bars which are typically made from flat bar and are welded to the baffles/tubesheet and "Rod" might refer to bundle slide rails which made from round bars and are welded to the bottom of the shell (only applies to TEMA "K" shells). Just a guess though.
