▎ 摘　　要

NOVELTY - The method involves inspecting and pretreating pipelines. The inner wall of the pipeline is coated with a layer of anti-corrosion paint. A layer of fire-resistant paint is applied to the inner wall of the pipeline. A layer of corrosion-resistant paint is coated on the outer wall of the pipeline. The pipeline is cold pressed. The coated pipelines are inspected. The inspected pipelines are stored or installed. USE - Method for coating natural gas pipelines. ADVANTAGE - The pipeline coated by the application has a long service life, is safe and environmentally-friendly.
