[MW:11572] Hardness Requirment

Hi All,

 

I am having a doubt on the hardness test required or not for the follwing:

 

Construction Code: B31.3

Matl Specn: SA106 Gr.B

Dia 4 - 12"

Sch: 40 & 80

Type of service: Sour

 

1) Is it required to refer NACE MR-00175 as well.

2) If hardness value goes high, then go for Heat treatment?

Pls. give your feed back.
