Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline technology, and in particular to a coating tool for fire protection pipeline anti-corrosion layer. Background Technology

[0002] The main function of the anti-corrosion coating on the outer wall of fire-fighting pipelines is to isolate them from external corrosive substances. The coating protects the pipeline substrate from acid and alkali corrosion, microbial corrosion, and chemical erosion, thereby extending the pipeline's service life. Specific functions include: 1) Blocking corrosive media: The outer wall coating uses thermosetting powder coatings (such as epoxy resin and polyethylene), which are tightly bonded to the steel pipe through electrostatic spraying or hot-dip plastic coating processes. This coating structure effectively isolates acidic and alkaline substances, moisture, and marine organisms in the soil, preventing the steel pipe from thinning due to rust and reducing its pressure-bearing capacity. 2) Improving corrosion resistance: The coating thickness is typically 0.3–3 mm, which, combined with the mechanical strength of the steel pipe substrate, can resist long-term corrosion in buried environments. Actual test data shows that even after 8 years of continuous use in highly corrosive environments, the inner wall remains smooth, while ordinary steel pipes may rust through in just 2 years. 3) Extending service life: By blocking external corrosive components, the service life of fire-fighting plastic-coated steel pipes can reach over 50 years, far exceeding the 10–15 years of ordinary steel pipes.

[0003] Existing coating fixtures for fire protection pipelines have been found to have shortcomings during use: they cannot reliably clamp the fire protection pipelines internally and rotate them around their own axis during the coating process, resulting in unsatisfactory coating effects.
