IS the external rust on High critical flange threat or not ?
what is the proactive action can be accomplished to avoid the external corrosion ?http://files.engineering.com/getfile.aspx?folder=f52e5ba3-940b-4082-ba46-3dbb07beafdc&file=flange_external_rust.GIF
Hello ,
I have process piping is high critical due to stream fluid ,constructed material is carbon steel ,maximum operation pressure 20 bar and temperature 30C.
piping class 3103 , size 6'' Sch.80 NT=10.97mm . as per the thickness measurement the minim actual thickness 6.0mm and the next...

thank you so much for prompt reply on my concerns.
Yes, can stop further corrosion occur but what about lowe thickness reading.
do you think GRE or none metallic wrapping can be a good solution to reset the strength of pipelines until the next Shutdown?

Recently I have observed CUI at several locations Upstream/downstream of expansion loops of pipelines especially: lower section of pipelines between 4 to 5 clock position) and the length of a corroded area less than a half meter along of the pipelines that marked on the attached image.
