There is a significant difference in the anti-corrosion and non-anti-corrosion effects of oil well pipes
Thread Content
The following images of well pipes show their condition after one and a half years of use in an oil field, providing a comparison between those with coating and those without. Without an anti-corrosion coating, scaling and corrosion are severe, while with the anti-corrosion coating (thickness of 120 microns), it remains intact. There is little difference between the coating of the used well pipes and that of the laboratory sample pipes.
Oil well pipes with anti-corrosion coatings remained in good condition after one and a half years, showing no significant wear or corrosion； Uncoated well pipes, on the other hand, suffer from severe scaling and corrosion. This proves that anti-corrosion coatings can effectively protect well pipes and extend their service life. .
