Re: [MW:14312] RE: 14299] COATING ON SS

Dear Mr.Pradip,

Thanks for your prompt reply.

Our client has no preference and he has no evidence of the need of such a coating layer on the SS 316 vessel, since we'll apply an insulation layer of 50mm on it.

Then, the SS is not in direct contact with Marine environment. Our evidence is that if we need such a coat, we shall do it on the insulation SS jacket as well and will never end with coating.

I would like to find a technical evidence that in this special case when insulating layer of 50mm+5/10 SS Jacket we don't need really coating.

If not, applying new insulating paint will much easier.

Please advise

Hello Lassad,

 

 

Does your client have any preferences or specifications on the types of paints to be used? If not otherwise read through clause 5.5 of the attached DNV spec.It' a free download in the web.

 

The other option would be to look in Norsok M-501, coating system 6 &7 (highlighted).

 

Let me know if it helps.316L stainless may require application of marine paints, since its prone to pitting in sea water environment.

 

Thanks.

Subject: [MW:14299] COATING ON SS

Gentelmen,

We are fabricating a SS 316L Fuel Gas scrubber 

For PP reasons, an insulation layer has to be applied. The client was asking to apply  an anticorrosion coating to the stainless steel material of the vessel for corrosion protection in marine environment.

In our experience we never did that for SS.

What do you think?. 

Is there any STD/Code that force that?

Design code: AMSE VIII Div 1

Location: Offshore Plateform
