[MW:17607] Re: Impact test for A106 - B31.3

Assuming you are asking for Gr B (refer Fig 323.2.2A,  falls under Curve B). what is your project amb temp? if it is colder than zero you might consider that temp, else imapct test at zero deg C is required for 35mm thickness.

Dear Experts,

 Process piping with material A106- thickness = 35 mm, design temp: 0 - 150 °C . My question: As per ASME B31.3, impact test for weld joint is required or not? If required, what temperature to impact test?

 

Thanks!
