Description

Technical Field

[0001] This utility model relates to the field of simulating the corrosion rate of gas pipelines using slatted plates, specifically a slatted plate device for simulating the corrosion rate of gas pipelines. Background Technology

[0002] The simulated gas pipeline corrosion rate plate is a test sample specifically designed to assess the corrosion of gas pipelines under specific environmental conditions. It is placed in the simulated environment of the gas pipeline, and after a certain period, the state of the plate before and after corrosion is analyzed to determine the potential corrosion rate of the gas pipeline. The plate can visually reflect the degree and rate of corrosion of the gas pipeline in actual or simulated operating environments. By periodically removing the plate and conducting inspections and analyses, it is possible to monitor the presence of corrosion risks and the rate of corrosion development in the gas pipeline in real time, enabling timely implementation of appropriate anti-corrosion measures and aiding in the assessment of the environment in which the gas pipeline operates.

[0003] In current technologies, the method of simulating the corrosion rate of gas pipelines using a hanging plate involves inserting a hanging rod into the gas pipeline, suspending the hanging plate on the hanging rod, and then sealing it with a flange or other structure. Furthermore, it is necessary to ensure that the hanging plate and the pipeline are made of the same or similar materials. In actual operation, because the hanging plate is suspended on the hanging rod, the airflow inside the pipeline can cause the hanging plate to move, easily leading to it falling off and affecting the accuracy of corrosion rate measurement. Therefore, a hanging plate device for simulating the corrosion rate of gas pipelines is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hanging plate device for simulating the corrosion rate of gas pipelines. It offers the advantage of easy fixing of the hanging plate, solving the problem that traditional methods for simulating gas pipeline corrosion rates involve inserting a hanging rod into the pipeline, suspending the hanging plate on the rod, and then sealing it with a flange or similar structure. Furthermore, these methods require the hanging plate and pipeline to be made of the same or similar material. In actual operation, because the hanging plate is suspended on the rod, the airflow inside the pipeline can cause it to move, easily leading to the hanging plate falling off and affecting the accuracy of corrosion rate measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hanging plate device for simulating the corrosion rate of gas pipelines, comprising a hanging cylinder, wherein the outer wall of the hanging cylinder is provided with a screw hole for use with fixing screws.

[0006] Furthermore, the hanging cylinder includes an inner ring and an outer ring, which are integrally formed structures.

[0007] Furthermore, the number of screw holes is four, and they are distributed in a circle at the same height on the surface of the hanging cylinder. The number of fixing screws is the same as the number of screw holes.

[0008] Furthermore, both the hanging cylinder and the fixing screws are made of polytetrafluoroethylene.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] This hanging plate device for simulating the corrosion rate of gas pipelines features a fixed screw and an integrated hanging cylinder. The fixed screw passes through the hanging plate and is then tightened to securely fix the hanging plate to the inner wall of the hanging cylinder. Multiple hanging plates can be fixed to the inner wall of the hanging cylinder simultaneously, thereby improving the accuracy of the gas pipeline corrosion rate test and preventing the hanging plates from falling off, thus ensuring the accuracy of the simulated gas pipeline corrosion rate test. Furthermore, the outer ring in the hanging cylinder can be placed between flanges for clamping, thereby providing a sealing and fixing function, enhancing the practicality of this hanging plate device for simulating the corrosion rate of gas pipelines.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 3 This embodiment of a hanging plate device for simulating the corrosion rate of a gas pipeline includes a hanging cylinder 3. The outer wall of the hanging cylinder 3 has screw holes 6 for matching fixing screws 4. The hanging cylinder 3 includes an inner ring and an outer ring, which are integrally formed. There are four screw holes 6 distributed in a circle at the same height on the surface of the hanging cylinder 3. The number of fixing screws 4 is the same as the number of screw holes 6. A hanging plate 5 is sleeved on the fixing screw 4, so that the fixing screw 4 can be used to press the hanging plate 5 onto the inner wall of the hanging cylinder 3.

[0017] The hanging plate 5 is oriented in the same direction as the airflow, and the hanging cylinder 3 and the fixing screw 4 are both made of polytetrafluoroethylene to avoid the metal material affecting the corrosion of the hanging plate 5.

[0018] By adopting the above technical solution, a corresponding number of threads 6 can be opened on the inner ring according to the number of hanging pieces 5 to be tested, so that all the hanging pieces 5 can be fixed to the inner wall of the hanging cylinder 3 by the same number of fixing screws 4, and the stability of the position of the hanging pieces 5 can be guaranteed.

[0019] Please see Figures 1 to 3 In actual installation, one end of the hanging cylinder 3 passes through the gas pipeline 1 and extends into the interior of the gas pipeline 1. The hanging plate device is sealed and installed together with the gas pipeline 1 by the flange ring 2. The outer ring of the hanging cylinder 3 is located inside the flange ring 2, which makes it easy to use the flange and flange ring 2 to clamp the outer ring of the hanging cylinder 3, so that the outer ring of the hanging cylinder 3 plays a sealing role.

[0020] By adopting the above technical solution, when installing the hanging cylinder 3, one end of the hanging cylinder 3 can be inserted into the interior of the gas pipeline 1, so that the outer ring of the hanging cylinder 3 is located inside the flange ring 2. Then, when connecting the two gas pipelines 1 through the flange ring 2, the outer ring of the hanging cylinder 3 placed inside the flange ring 2 can achieve a good sealing effect.

[0021] The working principle of the above embodiments is as follows:

[0022] The mounting plate device used to simulate the corrosion rate of gas pipelines is installed by loosening four fixing screws 4, then fitting four mounting plates 5 onto the four fixing screws 4 respectively, inserting the fixing screws 4 into the threaded holes and rotating the fixing screws 4 to fix the mounting plates 5 to the inner wall of the mounting cylinder 3, then inserting the mounting cylinder 3 into the gas pipeline 1 so that the outer ring in the mounting cylinder 3 is located inside the flange ring 2, and then using the two flange rings 2 to connect the two gas pipelines 1, and using the outer ring in the mounting cylinder 3 to achieve a sealing effect.
