Description

Technical Field

[0002] The gas distributed mainly includes three types: coal gas, liquefied petroleum gas and natural gas. my country's gas supply has increased significantly since the 1990s. Gas pipelines are corroded by wind, sun exposure, and gas impact vibration. The gas also contains a certain amount of moisture, which causes certain corrosion to the inner and outer walls of the pipeline. The outer wall can be treated by observation, such as painting, manual rust removal, and building anti-rust measures, but the inner wall of the pipeline is difficult to observe.

[0003] A gas pipeline rust removal device with publication number pushes a seat body through a connecting rod, thereby moving the entire rust removal device in the pipeline, and at the same time drives the rotation of a swivel ring through a driving motor, thereby driving a friction plate to rub against the inner wall of the pipe body to clean the rust stains generated on the inner wall of the pipe body. However, it is only suitable for gas pipelines with the same inner diameter. A gas pipeline rust removal device with a smaller inner diameter cannot be placed in the pipeline, and a gas pipeline rust removal device with a larger inner diameter is difficult to keep a close contact with the inner wall of the pipeline, resulting in a poor cleaning effect.
