Abstract
A method of operating a pipeline or apparatus is carried out by subjecting a pretreated component of a pipeline or apparatus to electrochemical corrosion protection. The pretreated component has surfaces previously treated with a coating of a treatment composition of a colloidal particle dispersion having inorganic nanoparticles with an average particle size from 500 nm or less that exhibit properties of Brownian motion. At least some of the inorganic nanoparticles of the treatment composition are ionically charged nanoparticles. The surfaces of the pretreated component are fresh surfaces or surfaces where any residues or deposits that have been previously formed on the surfaces from prior material contact have been removed prior to being treated.

A method of operating a pipeline or apparatus, the method comprising:
- subjecting at least one pretreated component of a pipeline or apparatus to electrochemical corrosion protection, the at least one pretreated component having surfaces previously treated with a coating of a treatment composition of a colloidal particle dispersion having inorganic nanoparticles with an average particle size from 500 nm or less that exhibit properties of Brownian motion, at least some of the inorganic nanoparticles being ionically charged nanoparticles, the surfaces being fresh surfaces or surfaces where any residues or deposits that have been previously formed on the surfaces from prior material contact have been removed prior to being treated.
A method of pretreating a component of a pipeline or apparatus, the method comprising:
- selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size from 500 nm or less that exhibit properties of Brownian motion, at least some of the inorganic nanoparticles being ionically charged nanoparticles;
- selecting a component of a pipeline or apparatus configured to undergo electrochemical corrosion protection;
- contacting the surfaces of the component of the pipeline or apparatus with a treatment composition comprising the colloidal particle dispersion, the surfaces of the pipeline or apparatus being surfaces of a fresh pipeline or apparatus and/or surfaces of a non-fresh pipeline or apparatus where any residues or deposits that have been previously formed on such surfaces of the non-fresh pipeline or apparatus from prior material contact have been removed;
- and
- subjecting the component of the pipeline or apparatus to electrochemical protection.
