316L ss cladding

[direcciontecnica]

I need to know which is the minimum thickness of a double claded material in 316L stainless steel on carbon steel.
I have to design one pressure vessel of diameter 1600 mm and height 3000 mm with dished ends "korbbogen" in carbon steel with double claded in 316L ss, only to prevent of the corrosion.
It is this possible? I need to find a solution to this.
Thanks.

Double sided cladding can and has been made by explosion cladding. Depending on thickness of base metal you could also weld overlay clad.

direccion tecnica,
The stainless steel cladded plate material is specified in the ASME SA 264 and the minimum thickness of the plate is 3/16" (2.73 mm), with the minimum width of plate at 10" (254 mm). Typically, for corrosion resistance you would expect some 1.5 - 3.0 mm thickness of the cladding, conforming to the ASME SA 264 requirements, including the soecific requirements for the undiluted thickness of the cladding, the ferrite control in the case of welded overlay or adherence requirements for the bonded cladding.
The cladding thickness depends on application, method of cladding, etc... It can vary from microns to 3/8" or more, refer to the mentioned spec for details.
However, can you please elaborate what do you mean by double cladded carbon steel plate? Is it both sides of the plate?
cheers,

Adding to the questions above, can you state the end sue of the plate?

I would certainly do a cost benefit analysis on the use of a double sided clad plate vs a solid sheet especially if you are talking thin materials.

I am confused and a little doubtful about your small vessel...

Thick carbon steel plate that is clad on both sides can make economic sense. The savings come from the difference in the cost between the carbon and clad plating minus the addtional cost of the plating operation.

With thin-walled plate like will be required for you small vessel, I am doubtful that there is any significant cost savings between the "double clad" and solid alloy plate.

Are we somehow exploring and evaluating the wisdom of a boss who does not understand what reasonable and prudent usage truly is....?
