This method is Stopple Operation ,a modern method for pipeline repair without shutdown ,as it is enable to replacement corroded parts or installing new accessories, branch,valve without stopping the pumping of the oil .
It needs of-course hot tapping operation after welding split tees and installing temporary sandwich valves and by-passes.
