Patent number: 11268644Abstract: A flow stopping tool for pipelines is disclosed, wherein the flow stopping tool comprises an inflatable balloon-like element that is in connection to a pressure rod. A hose is used for inflating the balloon-like element with a gas or a fluid, such that the balloon-like element can block a flow in a pipeline. A first end of the hose is in connection to the pressure rod and a second end of the hose is in connection to the balloon-like element. A part connecting the hose with the inflatable balloon-like element, but outside said balloon-like element, comprises a shock absorber for securing the hose-balloon connection.Type: GrantFiled: May 17, 2019Date of Patent: March 8, 2022Assignee: J. van Beugen Beheer B.V.Inventors: Leonard Van Beugen, Enver Coric
