[MW:31786] Re: SSPC SP 6 - 63

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"?

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.
