For controlling corrosion the following measures are important to regard:
● Be specific in selecting the right material. Metallurgic specialists define which metals are best to use.
● Also coating and painting are relevant topics to choose well.
● Adjusting production to increase or decrease the velocity in a pipe.
● In case particles are present in the fluid, a decrease may be better for the lifetime of instruments and pipes.
● Controlling the pH, reducing the chloride quantity, eliminating oxygen and bacteria and reducing the rate of metal oxidation with chemical injections.
● Effective and best composition of the chemicals to regulate the pressure in the pipeline or vessel where the fluid needs to go in.
