| 摘要 |
A method is presented for joining a first pipe to the wall of a second pipe. The second pipe contains a first fluid. The first pipe has an open end and a closed end. The method includes abutting the open end of the first pipe against the wall of the second pipe to create an abutment, forming a fluid-tight seal around the abutment, filling the first pipe with a second fluid, and creating an opening in the wall of the second pipe by cutting a section of the wall of the second pipe enclosed by the abutment. The second fluid may have the same pressure as the first fluid. |
