Heat Exchanger Piping

What should I watch out for, Shell and Tubes heat exchanger piping.

gpsvn,

Check out this link. www.red-bag.com/ Look under the Library section / design guides and then click the link for heat exchangers. It is a broad overview but it should get you started.

Also look in the training section.

Exchangers, Shell and Tube
Shell and tube exchangers should be grouped together wherever possible. Stacked shell and tube exchangers should be limited to four shells high in similar service; however, the top exchanger should not exceed a centerline elevation of 18 feet (5.5m) above high point of finished surface, unless mounted in a structure. Keep channel end and shell covers clear of obstructions such as piping and structural members to allow unbolting of exchanger flanges, and removal of heads and tube bundles.
Exchangers with removable tube bundles should have maintenance clearance equal to the bundle length plus 5 feet (1.5m) measured from the tube sheet to allow for the tube bundle and the tube puller.
Maintenance space between flanges of exchangers or other equipment arranged in pairs should be 1'- 6" (0.5m) (min.). Exchanger maintenance space from a structural member or pipe should not be less than 1'- 0" (300mm) (min.).

All good suggestion easy-e! I'd like to add afew suggestions too.

1. IF the heating media(H.M.) is over 450 Deg. F, don't use Teflon tape on the threaded instrument connections! It won't stand the heat!

2. IF you need to change the Teflon tape on these connections and use a pipe thread compound, make sure this compound can WELL stand the operating temperatures!

3. IF you discover the pipe compound is NOT working, and you’re up against a deadline, seal-welding these connection with the pipe compound still on the threads is a "bad" practice! Especially when the H.M. is Seal-therm and it flashes of at 750 Deg.s F!! ...And you didn't fully drain the system because of the deadline!

4. Never be the last man on the fire hose! ...If you are your the first one to catch the firewater slug coming thru the hose and if can knock you flat!

...These suggestions would have been real "helpful" in my career as a designer ...If I had known them first! *L*

Thank you, easy-e.

This is the answer I'm looking for.

Have good day.
