Hello, please someone clarify me this.
Regarding hardness tests under ASME B31.3 2010, Table 331.1.1, paragraph 331.1.7. is performing circumferential welds in pipes with 0.844 inch thick ASTM A 106 Gr. B. transport of sour gas.
The question is what are the criteria for assessing who takes shots hardness before heat treatment and after heat treatment?
And under that rule or code?
I appreciate your support by sharing their knowledge
greetings
