The stub could be hydrotested before testing (use hydrotested pipe). The weld(s) must be tested using non-destructive method.
Ive read it twice but still couldnt understand it. Im assuming it has something to do with hot tapping right. Im interested because of my involvement with several hot tapping done at refinery, power plant and petrochem. By the way, there are some prohibition ( no-no) related to hot tapping. If there is doubt in performing the operation then let experienced contractors handle the job such as the likes of TDW and Plidco.
