الزامات تست ضربه

Construction code ASME B31.3

Material A106 Gr. B

The thickness of Pipe. 17.48 mm

Temperature Limit 0^ F (-17.78^ C)

PWHT yes.

Table A-1 refers to curve B

Table 323.2.2A minimum Temperature without Impact Testing for CS showing under curve B 9^ F ( -12.8^ C).

My Question is for above case Impact testing for WPS qualification is required?  

آیا مورد بالا برای تائید WPS به تست ضربه احتیاج دارد ؟
