Problems solved by technology
Therefore, the corrosion of the oil pipeline due to the transportation of crude oil can also cause the failure of the pipeline, resulting in huge property losses and serious environmental damage, which should arouse our attention
[0003] Due to the limitation of the buried long-distance crude oil pipeline, the traditional ultrasonic thickness measurement technology cannot monitor the corrosion status of the pipeline in real time, nor can it grasp the corrosion trend of the pipeline in time

The invention provides a device for achieving crude oil long-distance pipeline thickness measurement monitoring through remote wireless data transmission and relates to an online thickness measurement monitoring device for a crude oil long-distance pipeline. The device comprises a crude oil long-distance pipeline measurement point thickness measurement data acquisition system and a data wireless transmission and data access network system. By the adoption of the online thickness measurement monitoring device for the crude oil long-distance pipeline, the defects that the corrosion condition of the pipeline cannot be monitored in real time and the corrosion trend of the pipeline cannot be mastered in time due to the fact that the traditional ultrasonic thickness measurement technology is limited by the crude oil long-distance pipeline in a buried place are overcome, and the device has the beneficial effect that the corrosion condition of the crude oil long-distance pipeline can be monitored in real time on the internet.
Description
technical field [0001] The invention relates to the field of petrochemical technology, in particular to an online thickness measurement and monitoring device for long-distance crude oil pipelines. Background technique [0002] Most crude oil needs to be transported to various refining and chemical enterprises by means of pipeline collection and transportation. During the process of crude oil collection and transportation, the inner wall corrosion problem caused by crude oil is caused. In fact crude oil contains H 2 S, CO 2 , SO 2 , O 2 These chemical components have a series of chemical and electrochemical reactions with the inner wall of the pipeline, resulting in corrosion of the inner wall of the pipeline. At the same time, the erosion effect of multiphase flow also plays a significant role in the internal corrosion of metal pipelines. In recent years, as my country imports a large amount of low-quality crude oil with high sulfur content and high acid content, the pr...
