を黒錆に変えて、錆の進行を抑制する。This invention has the above-described structure, and the anticorrosion tape 7 is a nonwoven tape 1 made of strong synthetic fibers such as nylon.
A tape cloth 13 is formed by sewing several sewing threads 12 made of strong synthetic fibers such as nylon in the longitudinal direction of the tape 1.
In addition, a clay-like adhesive 1 is formed by containing petrolatum as a main component, mixing inert silica for viscosity adjustment with the petrolatum, and further mixing and stirring a small amount of tannin and a rust inhibitor.
4 is permeated to form a permeable layer 15, and an adhesive layer 16 is provided on both ends of the permeable layer 150 as well as on the front and back surfaces of the permeable layer 150. The adhesive layer 16 is made of petrolatum as a main component, so that it can be semi-permanently evaporated or It does not harden and always maintains viscosity to form a semi-permanent anti-corrosion layer, which prevents the harmful effects of surface corrosion.Additionally, since it contains a rust inhibitor, it changes red rust to black rust and suppresses the progression of rust. .

ものである。In addition, the adhesive layer 16 maintains the blocking effect semi-permanently, has acid resistance, alkali resistance, salt resistance, and has excellent chemical resistance.
2. Connect the connecting pipes 3, 3, 3, 3 to 2, and add more petrolatum on the upper surface and less inert silica used as a hardening agent to make it easier to apply and have a thinner viscosity paste-like anticorrosion primer 4. was applied, and then more inert silica was applied than the anticorrosion primer 4 to the upper surface of the joint step/section 5, 5, 5.5 between the cruciform connecting pipe and the connecting pipe to strengthen the clay property. A first coating layer 8 is formed by coating the filled anti-corrosive material 6, 6, 6.6, and wrapping the anti-corrosion tape 7 around the cross-shaped connecting pipe 1, and then applying the anti-corrosion tape 7. The second coating layer 9 is formed by pasting a wide strip on both sides of the cruciform connecting tube 10, and then it is polymerized with a part of the second coating layer 9, and the anticorrosion tape 7 is applied from the cruciform connecting tube to each connecting tube. The third coating layer 10, 10, 10, 10 is formed by winding the 31st layer while strongly pulling.
By smoothing the entire surface from the state shown in the figure as shown in Figure 4, the corrosion protection method for the cruciform connecting pipe and the connecting pipe connected to the cruciform connecting pipe is ensured. This ensures reliable connection with the pipe and promotes corrosion protection.
