Anti-corrosion Steel Pipe
Anti-corrosion steel pipe refers to do
anti-corruption treatment for the ordinary steel pipe with special
technology, making the steel pipe equipped certain corrosion
resistance.
Generally used in waterproof, anti-rust, acid and alkali proof,
anti-oxidation and so on.
Different needs, different inside and outside wall corresponding
anti-corrosion measures.
Common are: epoxy coal tar anti-corrosion, anti-corrosion epoxy
coatings, urethane paint anti corrosion, IPN***0 water pipeline
corrosion protection, non-toxic paint anti corrosion,
anti-corrosion polymer coating, steel pipe lining anti corrosion
cement mortar, etc.
Anti-corrosion steel pipe is mainly used in special requirement or
engineering field with bad environment.
According to the steel pipe using location can be divided into the
outdoor steel pipe anti corrosion and buried steel pipelines anti
corrosion.
The ground: special surface coating anti-corrosive paint is still
the main method of steel construction and rack anti-corrosion.
Anti-corrosive paint protection function can be divided into the
primer, middle paint and top paint, all the layers of paint have
its characteristics, individual, several layers together, forming a
composite coating, improve the anti-corrosion performance and
prolong service life.
Underground: the corrosion reason of outer wall is more complex,
such as soil corrosion and stray current corrosion, microbiological
corrosion and so on, should choose a kind of good insulation,
chemical stability, resistance to plant roots antimicrobial
antiseptic material. Buried steel pipeline outer wall corrosion
mainly is electrochemical corrosion, coating anti-corrosion layer
in the outer wall of pipe is the most commonly used method. The
outer coating can reduce or block the corrosion current and slow
down the corrosion. Suggest using epoxy coal tar anti-corrosion,
there are national standard to depend on.
