Anti-corrosionSteel Pipe
Anti-corrosion steel pipe refers to do anti-corruption treatmentfor the ordinary steel pipe with special technology, making the steel pipeequipped certain corrosion resistance.
Generally used in waterproof, anti-rust, acid and alkali proof, anti-oxidationand so on.
Different needs, different inside and outside wall corresponding anti-corrosionmeasures.
Common are: epoxy coal tar anti-corrosion, anti-corrosion epoxy coatings,urethane paint anti corrosion, IPN8710 water pipeline corrosion protection,non-toxic paint anti corrosion, anti-corrosion polymer coating, steel pipelining anti corrosion cement mortar, etc.
Anti-corrosion steel pipe is mainly used in special requirement or engineeringfield with bad environment.
According to the steel pipe using location can be divided into the outdoorsteel pipe anti corrosion and buried steel pipelines anti corrosion.
The ground: special surface coating anti-corrosive paint is still the mainmethod of steel construction and rack anti-corrosion. Anti-corrosive paintprotection function can be divided into the primer, middle paint and top paint,all the layers of paint have its characteristics, individual, several layerstogether, forming a composite coating, improve the anti-corrosion performanceand prolong service life.
Underground: the corrosion reason of outer wall is more complex, such as soilcorrosion and stray current corrosion, microbiological corrosion and so on,should choose a kind of good insulation, chemical stability, resistance toplant roots antimicrobial antiseptic material. Buried steel pipeline outer wallcorrosion mainly is electrochemical corrosion, coating anti-corrosion layer inthe outer wall of pipe is the most commonly used method. The outer coating canreduce or block the corrosion current and slow down the corrosion. Suggestusing epoxy coal tar anti-corrosion, there are national standard to depend on.
