feed water heaters skirt
(OP)
When our supplier provides the drawing of high pressure and low pressure feedwater heaters , there is a part of shell called skirt , its position is after tubesheet in LP heater and its position is at steam inlet in HP heater , so what is the skirt ? IS it a part of shell ? what is its function and why its position differes from LP and HP heaters ? ( I didn't find such information in books or on the internet )

2) The function of the skirt on a vertical axis HX is to support the component. Customarily, it is NOT part of the pressure retaining boundary and therefor NOT part of the shell.
3) Are these all vertical axis feedwater heaters ? That is a bit unusual for modern power plants, most typically they are horizontal axis. Why wont you share the drawings with us, so that this discussion can have some meaning ?
4) For various thermal design reasons, it is not unusual to have different supporting schemes for HP and LP feedwater heaters. We will never know unless you make the drawings available to others ....
4) Where is this plant located and what are the governing codes and standards ?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Well, I for one am still confused about what you are talking about .... Does everyone else understand ?
Confidential, confidential .... oh yes, yes yes ...
However, I guess that it would be impossible for you to take up a bit of paper and sketch exactly what it is that you are trying to describe. Sometimes this is the only way for others to understand the issue ....
You don't have to reveal the client's name on the sketch ....
