Dear Experts,

 

Refer to Section 12.0(Flattening Test) of SA 106, ASME Sec II Part A.

This Section states that - " For Pipe over NPS 2 a section of pipe not less than........"

 

Question: Does the above Interpretation includes 2" or excludes 2" for the Flattening Test?

Do provide the reference of ASME/ASTM which supports the Interpretation.

 

The MTC recieved does not reflect the Flattening Test.( Material - 2", Sch 80, SA 106 Gr.B for Sour Service)

 

Hope to see as usual co-operation from everyone in Material Group.

 

Thanks & Regards
