[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"?

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?

Re: [MW:31778] Norsok M-601

Dear Sandeep. Thank you for sharing the link, but the only paragraph which talk about my concern is '' If the composite is a pipe or if it must be welded from one side, the buttering technique should be used. In this case the filler metal must provide an analysis equal to the clad metal and be compatible with the backing steel. Weld passes are made on the edge of the composite to butter the clad and backing metal. The buttering pass must be smoothed to the design dimensions prior to fitup. The same electrode can be used to make the join'' and again you have to deposit carbon steel filler metal on a buttering pass which is an alloyed metal. I think the statement is not applicable for cladad piping. Regards. On Mon, Nov 23, 2020 at 5:17 PM Sandeep Pr < prsandeep61@gmail.com > wrote: Dear Ali, Please refer the following link.

Re: [MW:31776] Materials and thicknesses in a project

 Such a broad question. Let's start with this question. What code were you planning on qualifying to? Assuming ASME IX, Purchase yourself a copy if this is in fact the code you need to qualify to, and begin studying. QW-451 For procedure qualification thickness limits and test specimens Should get you on the right track. I recommend getting in touch with somebody who is knowledgeable with creating a WPS/PQR. There's a lot more to it then what you asked in your question and what I've told you in my simple answer. More info is needed in order to help out. Cheers......
