RE: SSPC SP 6 - 63

Hi,

I think there’re some mix-ups in the specifications and interpretations. SSPC SP6 or other specifications are applicable for  surface preparation by blasting for application of paints.

For the refractories the criteria is a bit different. Following is the extract from  API -936, for surface preparation before applications of refractory.

You may read the standard, discuss and settle the issue with the client based on the API-936 guidelines.

Thanks.

Subject: SSPC SP 6 - 63

 

Hello everyone.

 

I encountered a requirement from a Licensor specification that internal surface should be prepared as per SSPC SP 6 - 63 prior to refractory application.

 

I know SSPC SP 6 means commercial blast but I have never encountered or saw a surface preparation requirement "SP 6 - 63".

 

Does anyone know what this means?

 

Thank you in advance.

Hi Sir,

Thank you for your valuable input. Indeed we have to discuss with Client and Licensor about this requirement. Normally we just do the SP-7 as specified in API 936 but we would need to install acid coating that would require a more clean surface so it would not peel-off. Thus we may need to clarify with the Refractory Supplier about the required acid coating and its required surface preparation before we talk to Client/Licensor. 

Anyways, do you know what "63" means in the "SP 6-63"?
