CORROSION-PROOF CAP

摘要

The present is provided to prevent corrosion of a pipe and, more specifically, relates to a magnet-attached rubber ring for preventing rust of a cut section of a cast iron pipe, wherein an adhesion plate having a magnet and a groove to be connected to a fitting pipe including an extension pipe and a protruding pipe is adhered to a cut section of a pipe by magnetic force and is adhered and hardened through adhesion means, the cut section is prevented from becoming corroded by a fluid or an external environment in a state where the adhesion plate stably comes in contact with the cut section of the pipe through pipe insertion of the fitting pipe, a pipe inner face coming in contact with an outer face of a metal pipe fitted and coupled to the outside of the protruding pipe after being welded through the metal pipe, it is possible to thereby stably fix the rubber ring, it is possible to minimize damage to the fitting pipe even when the fitting pipe made of a soft material is exposed to a fluid for a long period of time due to formation of a protruding portion, the rubber ring can be connected to the other magnet-attached rubber ring for preventing rust of a cut section of a cast iron pipe by welding or the like through a metallic connection plate fixed and adhered to the lower face of the adhesion plate in a state of being penetrated and inserted into the adhesion plate, and thus pipes separated from each other are easily connected to allow a fluid to smoothly flow even without using a separate connection pipe. The magnet-attached rubber ring for preventing rust of a cut section of a cast iron pipe according to the present invention comprises: a fitting pipe which is formed to protrude in a cylindrical shape to be connected to an upper face of an adhesion plate having a magnet therein; and a metal pipe which is inserted into an outer face of the fitting pipe and is installed in a pipe, makes a fluid flowing in one direction into a vortex to raise its movement speed, and prevents the fitting pipe from being damaged.
