A device for protecting a weld according to patent RU No. 20360, used to protect the internal butt joint - / 2 /.

The disadvantages of the analogue / 1 / include a shorter service life of the joints of known compounds due to the formation of burrs, which slows down the fluid flow rate and forces unreasonably to increase the working pressure in piping systems, which dramatically reduces the operational performance of not only the passage of the fluid flow, but also leads to gusts transport overhead and underwater systems for supplying liquid and particles, which collapses during the operation of pipes, burrs, which, falling into valves and instrumentation, oputno disables accessories. A tool for automated cutting and hardening of welds is difficult to manufacture and operate and requires significant costs for the use of used aircraft turbines in gas pumping, providing a high-speed flow of air from the blowing-out beads after machining.

The task of protecting the object of intellectual property as a useful model is the universality of a new technical solution with simultaneous technical excellence in protecting weld joints from destruction directly from the inside of the pipe product.

In addition, the analogue / 2 / can be practically applied only to the pipe outlet rigidly connected to the pipe.
