Re: [MW:18228] Regarding Material Upgrade API 5L Gr B Gr B to API 5L L415M

dear All, 

Grade B is Equivalent to PSL1.and  L 415  is  PSL 2 grade.

As per  standard ,Grade  PSL2 ,in welded Pipe , Impact test  ,DWT test , and NDT test is additional requirement .

So as per My suggestion it is better grade than Grade B and you can use it .

Thank you very Much

Dear Expert,

Initial Approval:

         Process : Jet A1 Fuel

         Code : B31.3

         Material - API 5L Gr.B ERW - Size 16"

        WPS Qualified - P1 Gr1/2 to P1 Gr1/2

Question: 

Due to unavailability of material contractor want to use higher grade that means API 5L L 415 M ,HFW pipes.

           1) Is it acceptable?

           2)If higher grade material,then any special requirement?

           3) Only 5pipes,other pipes are API 5L Gr B?

Thanks in advance.

Regards,

Naveen
