Control Corrosion

The pipelines that are used for transporting sea water to desalination plants are made of expensive steel alloys. However because of the salt content in water and also other atmospheric factors this pipe undergoes severe corrosion problem. This causes pits and holes in pipe surface making it useless and lead to huge replacement cost of pipes. Hence a way to control corrosion is needed.In this project use of different coatings to overcome corrosion is tested experimentally. Five types of coatings namely epoxy, aluminum, enamel, rubber, and chrome are coated on the samples prepared from actual pipeline used in the plant and the experimental results and analysis are summarized for finding the best coating for reducing corrosion of pipes. Among the five different coatings tested the rubber and epoxy coatings resulted with minimum corrosion rate and weight loss.

Control Corrosion

This review article characterizes the green inhibitors applied to control corrosion in metals and maintain the safety and profitability of the production process, since the corrosive phenomenon is insoluble, but can be mitigated with time. For this article, some case studies related to corrosion problems in metals are included, such as the accident in Aloha and the explosion in Guadalajara. Subsequently, the generalities of inhibitors for corrosion control are named, and the physisorption and chemisorption processes are compared. Then, inorganic, organic, synthetic, and green inhibitors are analyzed. The latter seek to replace the synthetic ones, for example, through aloe vera and other plant materials.

Weak Resistance

AbstractVarious methodologies are practically used to control corrosion. Coatings are the most widely used to protect metals against corrosion. However, due to the weak resistance of polymer coating against the penetration of corrosive solution to the metal/coating interface, the long-term corrosion resistance of the polymer coating is reduced gradually. Recently, nanoparticles have been added to coatings to improve their chemical, mechanical and optical properties. Nanocoatings either have constituents in the nanoscale or are made out of layers that are under 100 nm. Nanocoatings are used effectively to lessen the impact of a corrosive environment due to its various preferences, such as surface hardness, adhesive quality, long haul and, additionally, high-temperature corrosion opposition, and to improve its tribological properties, and so forth. Moreover, nanocoatings can be utilized in more slender and smoother thickness, which permits adaptability in equipment design and lower upkeep and working expenses. This review covers applications related to the management of metal corrosion, including the use of nanomaterials to produce high-performance corrosion inhibitors and corrosion-resistant coatings.

Testing And Evaluation

Before the Navy introduced thermally sprayed coatings to control corrosion on shipboard valves, joints, fittings, etc., the only means of protecting these parts was frequent repainting—often after intervals as short as six months—a labor-intensive and costly operation. This paper describes the Navy's experimental program to assess the benefits of a changeover to flame-sprayed aluminum and ceramic coatings of selected components; the reduction in man-hours achieved; the quality assurance procedure adopted; and the testing and evaluation of results.
