[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. 
 
Regards,
