1 TARIFF PORTABLE SANDING AND POLISHING DEVICE FOR REPLICA METHOD TECHNICAL FIELD The invention is in the fields of metallurgy and materials engineering, mechanical engineering, and non-destructive testing. Used in basic and technical fields such as inspection and metallography, especially in steel. It relates to a sanding and polishing device developed for the replica method in pipes. Thermal power plants, petrochemical plants, nuclear power plants, oil refineries, open offshore oil platforms, underground mining, drilling wells, fertilizer factories, facilities that produce or process chemical substances, especially those with high temperatures, high 10 Processes operating in environments containing pressure and chemicals are the application areas of the invention. It consists of mechanical maintenance units involved in these processes, which use non-destructive methods. companies providing inspection services, organizations performing damage analysis, laboratories companies providing these services or industrial and related fields covering all of these areas Academic institutions constitute the relevant sectors. 15 STATE OF THE ART The replica method involves the replication of large or non-disassemblable industrial machinery and metal parts. Used to examine the microstructure of parts without damaging their surface. It is a non-destructive testing method. With this technique, a one-to-one mold (copy film) of the metal surface is made. 20 They are taken and examined under a microscope in the laboratory to check for cracks or wear. It becomes clear that this is not the case. During the surface preparation stage, which is the first stage of the replica method. The area of ​​the part to be examined is sanded and polished. Thermal power plants, petrochemical plants, oil refineries, etc., are high-temperature facilities, high 25°C. In processes involving pressure and chemicals, almost the entire process is microstructural. They undergo periodic maintenance. In these types of processes, especially chemical and... Steel pipes are used for steam transmission. These pipes have a microstructural characteristic. in the examination known as the replica method, non-destructive in situ A technique is used to conduct microstructural examination. Various types of sandpaper are used. 30 and this method includes the stages of polishing and etching and removal of the replica The sanding and polishing stage of the pipe section is a very critical step. The replica method, including sanding and polishing stages, is currently used industrially. 2 with stone grinders, hand grinders or portable sample preparation devices This is done using all of these methods, where sanding and polishing operations are performed by the operator. Depending on one's skill, often excessive sanding results in the pipe or... various problems such as thinning of the walls of the cylindrical part and formation of undulations on the surface This leads to errors. This situation weakens the construction or 5 This prevents the microstructure from being visualized as desired in the replica. The main problems identified in the currently used technique can be explained as follows: -In current techniques, the replica method is not fixed to the pipe to be used. The sanding process performed takes 10 minutes, depending on the operator's dexterity. It is changing. This situation causes undulations to form on the surface, and The image quality of the microstructures obtained as a result of the replication method is quite high. It lowers it. -In the current method, the sanding and polishing process is still dependent on the operator. This indicates the extent of the sanding that has been done. This 15 The aim is to conduct a microstructural examination of the pipe using non-destructive testing. This leads to thinning of the walls and weakening of the construction. -In currently used techniques, the operator has to touch the end of the motor each time. He needs to change the sandpaper. This is a disadvantage in terms of time. When constructing, the occupational health risk in applications performed at height is 20. It increases. DEFINITION OF INVENTION The present invention eliminates the aforementioned disadvantages and the related technical 25 designed to bring new advantages to the field, especially for application in steel pipes. It relates to an abrasive and polishing device developed for the replica method. The aim of the invention is to create a microstructural environment that requires periodic maintenance and is particularly high-risk. such as pipes used in processes involving temperature, high pressure or chemicals. Sanding and polishing of cylindrical shaped parts during the replica process 30 The goal is to create a device that makes the steps easier. The device will cut the pipe or The cylinder part has a mechanism that secures itself to the surface. This The mechanism holds the main body. The main body has a motor and... 3 It includes a disc with sandpaper and polishing cloths on it. The disc sandpaper and polishing pads with different mesh sizes are placed on it respectively. The process of sanding or polishing is performed at the desired level by pushing it in front of the motor. This is accomplished by placing sandpaper or other materials in front of the motor mechanism. Thanks to the polishing cloths, the mechanism can be pushed to the desired level. 5 Sanding and polishing operations can be performed. Portable sample preparation. The technology used in their devices differs from the proposed invention in the following way. The portable sample preparation device has a power unit containing a battery and This power unit has a motor connected to it by a cable. A different mesh is attached to the end of the motor. The sanding process is carried out by attaching sandpaper with the specified dimensions. 10 The invention covers all stages of the sanding and polishing process used in the replica method. It has the equipment within its premises. This situation affects risky areas. This eliminates the security vulnerabilities of the replica acquisition process. Thanks to the device, the replica method's existing sanding and polishing stages are improved every 15 Eliminates the need to replace sandpaper and polishing cloths during each change. This eliminates the need for time savings and, indirectly, financial benefits. It provides cost savings. The invention replaces the sanding and polishing process in the replica method. This allows for production at the desired thickness. This situation is periodic. This minimizes mechanical weaknesses that may occur in the part as a result of maintenance. 20 The invention makes it possible to obtain clearer microstructure images. This can be listed as another advantage. The invention consists of two devices for attaching a body to a pipe or cylindrical part. It includes clamps. These clamps are 25 in size, depending on the thickness of the pipe or cylindrical part. It has an adjustable mechanism. Additionally, the clamps attach themselves to the pipe. It has butterfly screws for fastening. Main screw attached to the clamp mechanism. The bodies are bolted together with a distance of approximately 100 mm between them. It consists of two separate sheets of metal. The body requires sanding. The left rear side facing the pipe is open and has a rail mechanism on it. 30 A motor mechanism is located at the very rear of this opening. The fuselage... it moves on a fixed shaft placed in the exact center and on a rail It contains one large disc that includes smaller discs attached to its mechanism. 4 The desired sanding pressure can be applied to the smaller discs positioned on top of the larger disc. There is a Velcro mechanism to which the felt sheets can be attached.
