Subject: [MW:723] AET type exchanger test ring
To: materials-welding@googlegroups.com
Date: Sunday, 20 April, 2008, 9:16 PM

Dear Friends,

 

I have seen few heat exchangers on this forum. I am an end user of heat exchangers in refinery. My query is related to test rings of exchangers.

 

One of our new units has AET type exchangers [pull through type]. These exchangers have a floating tubesheet [FTS] with bolt holes and the floating head cover [FHC] is directly bolted to the floating tubesheet. The problem with this is that we can't carry out shell test using a conventional test ring due to several bolt holes on the floating tubesheet. Conventional AES exchangers have backing rings pressing the FHC against the FTS.

 

I checked TEMA website and it says, test rings for such exchangers are possible and the bolt holes in the tubesheet need to be temporarily plugged. It also says refer to 4.13 (3) of TEMA. Unfortunately we don't have the latest edition of TEMA.

 

Does any one have experience with test rings [for shell test] for AET type exchangers? I would appreciate a generic drawing / scheme showing how to carry  out shell test of such exchangers.

 

Thanks in advance.

 

Thanks and regards,

 

Jignesh
