Description

Plumbing emergency repair device {Plumbing emergency repair device}

The present invention relates to a pipe emergency recovery device, and more particularly, to a technique for urgently restoring a pipe through the recovery device when damage to the pipe occurs while using the pipe.

In general, pipes that transport gases or fluids must always be managed stably. As time passes, cracks occur in these pipes, and as the contents of the pipe, ie, gas or liquid, are ejected to the cracked area by high pressure through the cracks, the cracks increase and damage such as rupture of the pipe occurs. .

As described above, if the pipe is damaged, repair the ruptured part through welding, etc. to restore the pipe, or replace the damaged pipe with a new pipe.

However, among the pipe repair methods as described above, replacement with a new pipe has a problem in that it takes a lot of time and money to replace the pipe. There is a situation in which the welding operation cannot be performed because the operation is impossible.

Therefore, it is necessary to develop a technology that can quickly and accurately restore a damaged pipe so that the fluid can be supplied after the pipe is repaired without being limited to the on-site situation in a situation requiring urgent restoration of the damaged pipe.
