A pipeline protection device

Abstract

The invention discloses a pipeline protection device, comprising a low-temperature fluid pipeline and a high-temperature fluid pipeline, the low-temperature fluid pipeline intersects with the high-temperature fluid pipeline and communicates with each other; the fluid output port of the high-temperature fluid pipeline is arranged in the low-temperature fluid pipeline, And the direction in which the high-temperature fluid is output from the fluid output port of the high-temperature fluid pipeline into the low-temperature fluid pipeline is parallel to the flow direction of the low-temperature fluid in the low-temperature fluid pipeline. The pipeline protection device provided by the invention reduces the vibration amplitude of the pipeline, avoids the damage caused by material cavitation and high pressure and high flow rate to the pipeline wall, reduces costs, and ensures safe and stable production operation.

Description

technical field [0001] The invention belongs to the technical field of pipeline protection, and in particular relates to a pipeline protection device. Background technique [0002] Whether it is in the field of life or petrochemical production, the pipeline is a very common device used to transport various media, such as gas, liquid or fluid with solid particles. Due to the needs of the production process, such as figure 1 As shown, there is a T-shaped pipeline in which the low-temperature fluid 9 and the high-temperature fluid 10 converge in one pipeline. The erosion phenomenon makes the local pipe wall thickness thinner, and leakage will occur over time, and it will also cause pipeline vibration. At present, the conventional avoidance method is to inspect the thickness of the pipeline, and replace the pipeline in time when defects are found. This method is not practical because it needs to purchase testing equipment or entrust an external unit to do the inspection, and t...

Problems solved by technology

At present, the conventional avoidance method is to inspect the thickness of the pipeline, and replace the pipeline in time when defects are found. This method is not practical because it needs to purchase testing equipment or entrust an external unit to do the inspection, and the replacement of the pipeline requires the system to stop or the corresponding pipeline to be disconnected. Not only will it affect production, but it will also cause additional consumption of various production factors and increase costs
