AI Technical Summary

Technical Problem

The existing dewaxing devices for long-distance crude oil pipelines are ineffective at removing wax, resulting in wax residue, increased transport resistance and blockage risk, and frequent dewaxing operations increase costs and wear on the pipeline inner wall.

Method used

Design a cleaning component comprising a scraper and a cleaning brush assembly. Through the synergistic effect of the scraper and the cleaning brush assembly, enhance the cleaning effect on the inner wall of the pipe, reduce the frequency of wax removal operations, and improve the cleaning efficiency by using a scraper and an auxiliary scraper in conjunction with the cleaning brush assembly.

Benefits of technology

It effectively removes the wax layer on the inner wall of pipes, reduces mechanical wear, extends the service life of pipes, and reduces operating costs.
