[MW:9420] NDT after Weld

Hi there,

 

 

Welding Code: ASME IX

 

Construction Code: ASME B31.3

 

Material: 300NB x 34mm WT LTCS A333 Pipe

 

Question: How many hours after welding, that you are allowed to do radiograph test. Do you have to wait certain hours? Is there a minimum hours as per code?

 

 

 

Many Thanks,
