ABSTRACT:
The invention relates to a method and a device for blocking fluid in a pipe 1 onto which a positioning unit 2 is hermetically mounted and through which a hole is drilled in the pipe while maintaining a hermetic seal. An expandable body 8 is inserted into the pipe with the aid of a blocking implement 7 enclosed in support tube 9. The expandable body is expanded to temporarily block the flow of fluid in the pipe. The support tube has a supporting structure for supporting the expandable body against the flow of fluid during insertion into the pipe, after insertion, during expansion and after expansion. The support structure increases the capability of the expanded body to withstand the high pressure of the fluid.
