Dear Experts.

I want to make the RFT tubes standard following ASTM E2096. But our workshop can't create the angles following requirements at Fig 4 (Flaw C*F*D: 150 Degree - Flaw E: 65 degree).

I want to know the significance of degree value (150* 65) in process signal and wall lost value?

Thanks for attention!
