Method and system to open and make accessible the interior of pipe leads

摘要

The revised version has a device inserted in with a joint that makes it possible access to the revised unit when separated from one another. It is treated around a tapping instead of the revised opening. It may be positioned such that the pipe-lead system is opened, and treated about the through-flow position on the pipe-lead system. Branching of the opening position, of the pipe-lead system, may be built through the in-flow and out-flow sides of the through-flow position.
