Description

Technical Field

[0001] The invention relates to the field of natural gas, and in particular to a natural gas pipeline internal cleaning device. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas (including associated gas produced in oil fields) from the production site or processing plant to urban gas distribution centers or industrial enterprise users, also known as a gas transmission pipeline.

[0003] In order not to affect the use of natural gas pipelines, the pipelines need to be cleaned. It is better to clean the outside of the pipelines. When cleaning the inner wall of the pipeline, the pipe cleaner is currently widely used.
