採られている。2. Description of the Related Art In the fluid transportation of earth, sand, ore, and other solid materials, the solids are usually suspended in a liquid or gas and transported to a destination location by means of a transport pipe. The inner wall surface of a transport pipe gradually wears out or wears down due to friction and impact caused by the flow of solid materials such as earth, sand, ore, but naturally, the wear and tear is greater in curved pipes than in straight pipes. Severe damage due to wear and tear. As a result, bent pipes have a short service life and must be replaced frequently to avoid bursting or breaking. Of course, even in a straight pipe section, damage may occur locally due to wear and abrasion depending on the flow condition of the fluid conveyed material. Therefore, even if one pipe body is replaced, the operation of the transportation line must be stopped for the replacement work, which inevitably causes a large operational loss. In order to reduce such losses, various anti-wear measures have been taken in the past.

知られている。[0003] Conventionally, as a wear-resistant measure, it has generally been carried out to apply abrasion-resistant processing to the inner wall surface of the pipe. There are several known methods, such as connecting and inserting the metal particles and applying a resin mixed with wear-resistant materials such as metal particles and ceramic particles.

あるいは不可能である等の問題点がある。[Problems to be Solved by the Invention] All of the conventional anti-wear measures described above aim to improve durability by protecting the inner wall surface of the tube, and each has achieved certain effects. However, as long as the inner wall surface of the tube is subjected to wear-resistant processing, operational inconvenience is a common and major issue. In particular, it is difficult or impossible to perform such wear-resistant processing on curved pipes, pipes with small diameters, complex shapes, and long distances between the opening and bend. There are problems such as whether it is possible or not.

このようなことから、管内面の塗布される耐摩耗性樹脂

も限られることになる。The second problem is that the abrasion-resistant treatment applied to the inner wall surface, for example, the adhesion of the applied abrasion-resistant resin is not uniform, and if the diameter of the tube becomes irregular, the fluid Flow resistance increases, pressure loss increases, and transportation power increases. In addition, wear resistance decreases due to the roughening of the inner wall of the pipe. Alternatively, a crosslinking phenomenon may occur, causing blockage within the pipe. For this reason, the thickness of the wear-resistant resin applied to the inner surface of the tube is limited, and the effect on wear resistance is accordingly limited.

Intrusion of liquids, etc. has become a problem. In all conventional anti-wear measures, as long as the inner wall surface of the tube is processed in a predetermined manner, it has not been possible to completely avoid the above-mentioned problems. Therefore, the present invention has been made to solve the problems of the conventional processing methods adopted for wear resistance measures, and the main purpose of the present invention is to impart structural strength to the pipe body. An object of the present invention is to provide a method for reinforcing a tube body by increasing the durability of the tube body. Another object of the present invention is to provide a method for reinforcing a tubular body that allows easy reinforcing work regardless of the size or shape of the tubular body. Still another object of the present invention is to provide a reinforcing member with excellent wear resistance for realizing such a reinforcing method.

In addition, the reinforcing member for the tube used in this method is made of a wear-resistant composition mainly composed of a thermosetting resin and a hard material, and has a gutter-shaped shape that can be fitted along the target tube. The main point is to have the following. The wear-resistant composition constituting the reinforcing member of the present invention consists of a thermosetting resin and a hard material. Thermosetting resins are not particularly limited, and include, for example, urethane resins, epoxy resins, unsaturated polyester resins,
Examples include epoxy acrylate resin, furan resin, polyimide resin, and silicone resin. Among these, urethane resins and epoxy resins are most preferred, and both one-component and two-component urethane resins are excellent. It should be noted that these thermosetting resins can be mixed and used as long as there is no adverse effect.

It is not limited to polyhedrons, cylinders, prisms, etc.
Items of different shapes and sizes can be used together. The blending ratio of the thermosetting resin and the hard material used in the present invention is not particularly restricted, but if the amount of the hard material is too small, it will naturally not be possible to exhibit wear resistance performance. If the amount is too high, the bond with the resin becomes brittle, which not only makes it impossible to exhibit wear resistance but also causes the coating to lose its properties. Specifically, the amount of the hard material is 10 to 1000 parts by weight, preferably 50 to 600 parts by weight, per 100 parts by weight of the resin.

着補強できる。[Function] The pipe body, especially the inner circumference of the curved part of the pipe, is where wear and abrasion is most likely to occur due to friction and impact caused by fluids containing earth, sand, ores, and other solid materials. When the wall thickness becomes thinner due to wear and tear, it becomes unable to withstand even the slightest impact from flowing objects, making it more likely to burst or break. According to the present invention, by attaching and fixing or adhering a reinforcing member to the outer wall surface of the tube, structural strength is imparted to the tube, thereby preventing such rupture or breakage. In addition, since the reinforcing member itself is made of a wear-resistant composition, even if part of the pipe body is completely worn away and the reinforcing member is exposed to the pipe line, this reinforcing member It can function as a part of the body. Further, the reinforcing member can be pre-fabricated to standard dimensions and reinforced by adhesion to the required pipe section when newly installed or at any time.

補強部材１が管の一部となって対処できることになる。As a result of actually using the bent pipe reinforced with the reinforcing member 1 of the present invention in a coke transport line for 18 months, the inner wall surface of the pipe fixed with adhesive was locally worn out. Although it was observed that the reinforcing member of the present invention was exposed inside the pipe, there was no problem with the operation at all. In addition, when the reinforcing member 1 was fixed with a steel band, coke fine powder started to leak from between the reinforcing member 1 and the pipe wall on the 80th day, so the steel band was removed and the same resistance as that of the reinforcing member was removed. The abrasive composition was attached as an adhesive, and the operation continued for 15 months. The same type of SGP bent pipe without reinforcing member used for comparison had a hole on the outside of the bend on the 35th day, and the operation was stopped and the reinforcing member of the present invention was glued from the outside and operation continued. . Even if the constituent wall thickness of the bent pipe 2 wears away and becomes thinner, the outside is covered by the reinforcing member 1, so the reinforcing member 1 can prevent it from immediately bursting or leaking fluid. It is. Therefore, the wall thickness of the reinforcing member 1 can be made thick depending on the usage conditions of the curved pipe being handled, and if the thick reinforcing member 1 is used, even if the curved pipe is worn out and perforated. ,
This means that the reinforcing member 1 becomes part of the pipe.

。Since the reinforcing member 1 is obtained by molding the above-mentioned wear-resistant composition using a mold, the reinforcing member 1 can be freely manufactured in terms of wall thickness and overall dimensions. Moreover, since the manufacturing method using a mold allows the inner and outer surfaces to be finished smooth, there is no problem in adhering the tube along the outer surface of the curved pipe. Further, if necessary, only the portion corresponding to the maximum wear portion of the curved pipe can be made thicker than other portions in advance.
