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.
