The result shows that rubber anti-aging coatings have very important effect on aluminum alloy corrosion .

Corrosion protection of poly o-toluidine anticorrosive coating for carbon steel;

Technologies of anticorrosive coating for marine concrete protection

Based on an introduction to the detection technology of external anticorrosive coating of buried pipeline in service, the narration is given to the working principle, measuring techniques of PCM system, and basic methods of detecting the rank of anticorrosion coating according to the relevant technological regulation and standards.

The DCVG & CIPS measurement technique is a main method applied in integrity testing of external anticorrosive coating of gas transmission pipeline.

In pipeline connection,conventional welding technique affected anticorrosion performance due to the destruction of anticorrosive coating on pipeline inner wall,whereas the use of HP(high pressure)snap joints can ensure the integrity of anticorrosive coating thoroughly and solved the problem of internal end-to-end joint coating for pipeline weld.

In this article, the technique research and development process of application of poly ethylene to anticorrosion layer on piping for conveying oil was introduced, and the optimum composition and technical route to change the properties of poly ethylene were presented as well.

Fast connection stud of high pressure piping is used to replace for welding in connection of piping so as to keep the integrity of the anticorrosion layer.
