Re: [MW:31789] Re: Different of EFW/ERW pipe

dear 

check the pipe standard stenciled on the pipe for identification. It could be alloy steel pipe of  ASTM A 672 Grade A 45 etc......

[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.

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.

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......

Would you say what is the reason of this statement" When welding clad materials from both sides, the C and CMn steel shall be completely welded prior to welding the cladding. C or CMn steel or low alloyed steel weld metal shall not be deposited onto a high alloy base material or weld metal.'' ?

How is it possible for cladded piping?

Dear Sirs,,

We required the welding electrode for subjected grade and procedure for welding on the castings.

Already the job was welded by E9018M and found low hardness after quenching the job. To reach the 50 HRC, what is welding electrode to be used?

Thank you

RE: [MW:31762] Norsok M-601

Hi Ali,

 

The statement in Norsok M-601 is self-explanatory. For double sided welding following the sequencing guidelines  specified in the document. While  performing single sided welding of clad pipes, the entire girth welding is typically done  with alloyed  filler metals/ electrodes. Sequences are  different than  welding a double sided welds.

The attachment explains how the single & double sided welds are performed in cladded pipe.

 

Thanks.
