Corrosion is an important industrial problem, as it can cause accidents (breakage of a piece) and, in addition, represents a significant cost, since it is estimated that five tons of steel in the world dissolve in a few seconds.
What is corrosion?
Corrosion is a chemical reaction (oxidation-reduction) in which three factors intervene: the pipe, the environment and the water or also through an electrochemical reaction. More generally, it can be understood as the general tendency that materials have to seek their form with the greatest stability or lowest internal energy. Whenever corrosion is caused by an electrochemical reaction (oxidation), the rate at which it takes place will depend to some extent on the temperature, the salinity of the fluid in contact with the metal and the properties of the metals in question.
To avoid corrosion in metal pipes, there are methods that must be considered depending on each environment and use, the maintenance costs and effectiveness of the system chosen must be taken into account.
Today one solution is to use anticorrosive materials. Our 31 years of experience have taught us that the best way to avoid corrosion is through both internal and external coatings of piping systems.
Coatings
They are used to insulate the internal regions of the piping system against chemical materials. These are a great source that initiates corrosion or rust. Oxidation occurs in humid places, but there are methods to prevent the metal from rusting, for example: a layer of paint.
At SIESA we have internal coatings of PFA, PTFE and PP. Which help avoid internal corrosion and has a useful life of up to 40 years without maintenance costs. And high resistance resin paints for anti-corrosion of the pipe.
