A corrosion prevention process to protect the piping of a dry pipe sprinkler system from corrosion is described. The process includes the selection and application of suitable corrosion inhibitors to interior portions of the piping. The corrosion inhibitors used in this process may include volatile corrosion inhibitors.

A method for eliminating hydrocarbon fouling and reducing pumping power during hydrocarbon transportation. A dielectric layer covers the inner surface of a pipeline for transporting a water-hydrocarbon mixture. A proximity electrode is immersed in the water-hydrocarbon mixture, and an electrical voltage is applied across the dielectric layer. A buffer layer of water is formed on the dielectric layer since water is electrically attracted from the water-hydrocarbon mixture. This water layer, located between the dielectric layer and the water-hydrocarbon mixture, eliminates hydrocarbon fouling on the inner surface of the pipeline or any other internal surface that needs fouling protection. Alternatively, the dielectric layer covers an outer surface of the pipeline and is covered by an external conducting layer. Applying a potential difference between the proximity electrode and the external conducting layer still forms a water buffer layer between the inner surface and the water-hydrocarbon mixture, which eliminates hydrocarbon fouling.

A process and composition for coating a pipe and a pipe support includes mixing a cellulose acetate, a plasticizer, and an oil together so as to form a solid mixture, heating the solid mixture so as to form a liquid state, covering an area of the joinder of the pipe and the pipe support with the liquid state, and drying the liquid state on the area of the joinder. An ethylene-based polymer stabilizer is added to the mixture of the cellulose acetate, the plasticizer and the oil. The oil migrates by gravity from the liquid state from the covered pipe into an area of contact between the pipe and the pipe support. The liquid state is applied around the outer diameter of the pipe and over the outer surface of the pipe support underlying the outer diameter of the pipe.
