PROTECTOR FOR PROTECTING PIPES WITH WEIGHT COATING AGAINST CORROSION Russian patent published in 2023 - IPC C23F13/02 

FIELD: pipes.

SUBSTANCE: protector for protecting pipes with weight coating against corrosion constitutes a system of protective corrosion protection of steel structures including an external metal polymer shell (pipe-in-pipe). Protector for protecting pipe-in-pipe type pipes with weight coating against corrosion consists of a pipe, a metal polymer shell, insulating coating, a protector made of a protective alloy, steel screws, clamps, synthetic mesh, and concrete coating. The edges of the protector are wrapped tensioned around the pipe after being installed on the insulating coating of the pipe. The edges of the protector are further secured to each other with steel screws after overlapping one edge with the other. The protector is brought to metal contact with the pipe mechanically by screws screwed into the protector for securing through the insulating coating. Metal contact of the protector with the metal polymer shell is prevented by applying the synthetic mesh pulled to the protector by synthetic clamps over the protector.

EFFECT: reliable protection of each pipe with a concrete weight coating having a metal polymer shell against corrosion.
