防錆用チューブに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing rust on the inner wall of a building's self-supplying water pipe by forming a synthetic resin film to prevent rust inside the pipe, and to a rust-preventing tube.

の管更生工法が実施されている。This is caused by the plating inside the iron water pipes peeling off and rusting, or
This is because scale has occurred. Red water is the product of this rust dioxide process and iron bacteria deposits dissolved in water. Particularly when drinking water is used indoors, the generation of red water can seriously impede drinking and washing. Therefore, in order to eliminate the occurrence of this red water, it is necessary to clean the water supply pipes to remove rust and the like from the inner walls, and to form a film of synthetic resin or the like on the inner walls of the pipes. Conventionally, in order to form this film inside bent pipes, a liquid synthetic resin that hardens under certain conditions is poured in, applied uniformly to the inner wall, and then cured at room temperature or heated to form a hard film. Various pipe rehabilitation methods are being implemented to

すこととなり、工期も長くなり費用も増大する。When forming a pipe inner coating, if the coating is not uniformly formed, rust will occur again in a short period of time in the incomplete coating area. For example, a liquid synthetic resin with low viscosity is poured into a pipe, a brush or molded material is inserted, and it is applied to the wall surface by remote work.The resin is then heated with hot air and hardened. The resin drips and precipitates, causing the resin to partially harden.
This will result in an uneven film. Also, if the pipe is sloped, it collects at the bottom of the slope and hardens, filling the inside of the pipe and making it difficult for water to pass through. Another method is to pour a highly viscous liquid synthetic resin into a pipe and move it using high-pressure air at a specific temperature. (Because it adheres,
There is a method of forming and curing a film to a certain thickness by controlling the amount of air, pressure, and heat. However, because the thickness of the adhesive varies depending on the local condition inside the pipe, and because it is not retained in the required place until it hardens, a thick film has to be formed overall, so a large amount of resin is required. In addition to using it, it requires a skilled worker. In addition, since high-pressure air and a large amount of hot air are generated, large-scale mechanical equipment is required, which is not only expensive but also limited to specific locations or buildings, making it uncommon. Furthermore, since these methods flow liquid synthetic resin into the pipe, it adheres to the pulp and instruments in various parts of the pipe, and once it hardens, it becomes immovable1. In order to serve as a hot air intake/exhaust port, the pulp etc. must be replaced with other parts in advance. However, many of the pipes where rust occurs are old and brittle.
During replacement, parts other than the joints such as pulp may move and be damaged.
They are often discovered after the fact, and the damage is often located deep inside the building, requiring the destruction of a part of the building for repair, which lengthens the construction period and increases costs.

等の問題点があった。As mentioned above, the conventional pipe rehabilitation method uses liquid synthetic resin as the material for film formation, pours it into the pipe, applies it to the wall, and then heats it to harden the resin, so a certain amount of time is required. As the resin moves, a uniform film is not formed inside the pipe, resulting in incomplete parts of the film, which can lead to rust immediately, poor water flow, and pulp, etc. in various places during construction. In addition, the machinery and equipment required for construction are large, and construction is not only limited to a specific building or location, but also takes a long time. There were problems such as increased costs.

放された一部を密封したものである。The means of the present invention for solving the above-mentioned problems consists of cleaning the inner walls of water supply pipes installed in buildings to prevent rust, and furthermore, applying a hardenable flexible synthetic resin film inside the vaginal pipes after washing and drying. An inner wall of piping characterized by inserting a rust prevention tube, pressurizing the inside of the tube to bring the outer surface of the tube into contact with the inner wall of the piping, and heating at least one of the tube and the piping to bring them into close contact. This is a rust prevention method. Further, a tube made of a curable flexible synthetic resin film,
It is usually formed into a band shape that can be rolled or folded into a coil, and can be cut at any position approximately at right angles to the longitudinal direction, and can be inserted into a water supply pipe to pressurize the inside. This is a tube for rust prevention on the inner wall of a pipe, characterized in that the tube is brought into close contact with the inside of the pipe to form a rust preventive film on the inner wall of the pipe. The tube is made of synthetic resin and a protective member, and is equipped with a means for easily peeling off the protective member and discharging it outside the tube after the tube is inserted into the tube and attached. This tube is made of resin with a fibrous material mixed into the membrane reinforcement, and has a sealed portion that is open for movement within the tube.

ができる。As explained above, by using a tube made of a flexible synthetic resin film, the present invention can be used to form an anti-rust film on the inner surface of water supply and hot water supply piping in buildings such as buildings after cleaning the inside of the pipe. Because it is a molded tube made of flexible synthetic resin film, it can be folded and bent, so it can be easily transported in the form of a plate, and it can be cut to the required length on site during construction. Furthermore, by simply removing the valve attached to the pipe, the pipe can be bent into a small size and easily inserted without causing damage to other parts of the pipe. In addition, the pre-caulked resin film is uniform, so while it is heated and hardened,
No resin drips, even if the inside of the pipe is uneven.
Since the resin film adheres closely to the surface, the resin film can be formed uniformly.Furthermore, when fibers are mixed into the resin, the hardened film does not crack or peel off, creating a rust-preventing film, which causes red water, etc. Jurisdictional rehabilitation can be carried out to prevent this.
