Testing ratio for paint thickness on industrial equipment and pipelines
Thread Content
What is the inspection ratio for the paint film thickness of industrial metal pipes after painting? For example, if a anti-corrosion factory has 1,000 meters of pipes that have already been painted, how many samples should be taken for inspection? It would be best to cite the standards. Please advise: handshake
The anti-corrosion coating applied by thermal spraying has a thickness of 0.5–1 mm, while the fluorine-lined plate has a thickness of 2–10 mm; these values are determined based on the various properties of the pipeline.
The anti-corrosion plant has 1,000 meters of pipelines that have been painted; sample inspection points are required, as specified in the drawings
The drawings specify it. . . Then why am I still asking here? I just want to know the provisions in the relevant regulations. . Seeking advice
