Corrosion of Reactor Vessel (SS 316L)
Corrosion of Reactor Vessel (SS 316L)
(OP)
Dear All,
We made a reactor vessel with a limpard around it for textile chemical plant. It was manufactured in 2010 and now rust had appeared on its surface. Other than analysis of the rusted powder what you suggest to be done to dig the root cause out? Following is its design data:
Shell and Dish Ends : A-240 SS 316L
Coil: A-312 TP 304
Design Pressure: 6Bar
Design max. temp: 200 C
Design min. temp: -29 C
Code : ASME Sec VIII Div. I, 2007 Add. 09
Vessel was not U stamped.
Regards,
Umair

As you see, there are many scenarios where the rust could appear, but first you need to stop the contaminants coming in contact with the reactor, then clean, pickle and passivate again.

gr2vessel- he might be using dodgy terminology- he might mean stainless steel corrosion products.

The corrosion product is on the ID. Bottom dish end and shell, though the agitator shaft is not having any sign of corrosion. The customer is not ready to tell the chemical being used in it, as he say its a trade secret.
Dear gr2vessels,
Vessel was in continuous operation. And yes corrosion appeared recently.
Below is the link of rust / corrosion sample we are about to send for analysis.
