Steam/Condensate Line Failure
Steam/Condensate Line Failure
(OP)
Return condensate lines from the equipment using the steam to the condensate flash drum is seeing regular failures in many elbows and fittings. I was wondering about any potential causes for these fialures within the condensate lines.
We believe it to be a combination of high velocities with two phase flow that is causing erosion. If velocity is the problem, is there any standards for the Max flow rate you can have in condensate lines
The Plant in question is an upgrader that has been running for approx 20 years with increased production of oil and no improvement done on the steam and condensate system. (if that helps any)

billNYE, a good start for you would be to read the documents of Spirax Sarco in this site: http://ww
Good luck!

To limit flashing to only the outlet section, it may help to have an outlet flow resticion orifice or capillary tube.

although most usually considered 'innocent' or even "non-existent".

The proper water treatment will help...lots of people will sell you chemicals
You should be happy that you got 20 years out of the system
Was yours Schedule 40 or 80..???
Section by section, replace what exists with a schedule 80 carbon steel system.
It will outlast you..
