Description

Hanging piece device for simulating corrosion rate of gas pipeline Technical Field The utility model relates to the technical field of hanging pieces for simulating the corrosion rate of a gas pipeline, in particular to a hanging piece device for simulating the corrosion rate of the gas pipeline. Background The hanging piece for simulating the corrosion rate of the gas pipeline is a test sample specially used for evaluating the corrosion condition of the gas pipeline in a specific environment, is placed in the simulated environment of the gas pipeline, and after a certain period of time, the corrosion rate possibly faced by the gas pipeline is determined by analyzing the states before and after the hanging piece is corroded, the hanging piece can intuitively reflect the corrosion degree and the corrosion rate of the gas pipeline in the actual operation or simulated operation environment, and the hanging piece is taken out periodically and is subjected to detection and analysis, so that the corrosion risk and the corrosion development speed of the gas pipeline can be known in real time, corresponding corrosion prevention measures can be taken timely, and the environment where the gas pipeline is positioned can be evaluated. In the prior art, the hanging piece for simulating the corrosion rate of the gas pipeline is inserted into the gas pipeline through the hanging rod, is hung on the hanging rod and then is sealed through structures such as flanges, the hanging piece and the pipeline are required to be guaranteed to be identical or similar in material, in the actual operation process, the hanging piece is hung on the hanging rod, and the hanging piece can be driven to move by the air flow in the pipeline, so that the hanging piece is easy to fall down, the accuracy of corrosion rate measurement is influenced, and the hanging piece device for simulating the corrosion rate of the gas pipeline is provided to solve the problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a hanging piece device for simulating the corrosion rate of a gas pipeline, which has the advantage of being convenient for fixing the hanging piece, and solves the problems that the hanging piece is easy to drop and further influences the accuracy of corrosion rate measurement because the hanging piece is hung on the hanging rod and the air flow in the pipeline can drive the hanging piece to move in the actual operation process because the hanging piece is sealed by structures such as a flange and the like after the hanging rod is inserted into the gas pipeline and the hanging piece is hung on the hanging rod. In order to achieve the purpose, the utility model provides the technical scheme that the hanging piece device for simulating the corrosion rate of the gas pipeline comprises a hanging barrel, wherein the outer wall of the hanging barrel is provided with a screw hole matched with a fixing screw. Further, the hanging barrel comprises an inner ring and an outer ring, and the inner ring and the outer ring are of an integrated structure. Further, the number of the screw holes is four, the screw holes are distributed on the same height of the surface of the hanging barrel in a round shape, and the number of the fixing screws is the same as the number of the screw holes. Furthermore, the hanging cylinder and the fixing screw are made of polytetrafluoroethylene. Compared with the prior art, the technical scheme of the application has the following beneficial effects: This a string of piece device for simulating gas line corrosion rate, through being provided with the section of thick bamboo of hanging of set screw and integral type, can utilize the set screw to run through the string piece, then screw up the set screw, thereby be fixed in the inner wall of hanging the section of thick bamboo with the string piece is firm, can be fixed in the inner wall of hanging the section of thick bamboo with a plurality of string pieces simultaneously, thereby improve the accuracy of gas line corrosion rate test, can also avoid the string piece to drop simultaneously, thereby guarantee simulation gas line corrosion rate test accuracy, the centre gripping between the flange can also be arranged in to the outer loop in the section of thick bamboo of hanging, thereby play sealed and fixed action, make this a string of piece device for simulating gas line corrosion rate's practicality reinforcing.
