regions of the corrosion cells from the corrosive medium and stops corrosion. b. Oxygen scavengers, these are compounds which react with dissolved oxygen and remove it. from the neutral or alkaline corrosive environment such as sodium sulphite or hydrazine (used to. Corrosion has a huge economic impact. About a fifth of the world's annual steel production simply goes towards replacing parts damaged by corrosion. Even though it may involve higher up-front cost, correct and efficient corrosion protection at source helps save money and resources in the long run. Interface inhibitors control corrosion by forming a film at the metal/environment interface. Interface inhibitors can be classified into liquid- and vapor-phase inhibitors. Internal corrosion of pipelines is controlled by cleaning the pipeline (pigging) and by adding continuous and/or batch inhibitors. This paper reviews fundamental corrosion issues concerning the Crude Unit process. It is, in concise form, a description of the process and major equipment @inproceedings{Bagdasarian1996CrudeUC, title={Crude unit corrosion and corrosion control}, author={A. J. Bagdasarian and J. Feather and National Corrosion Service The National Corrosion Service (NCS) is operated by NPL on behalf of the National Measurement System to provide a gateway to The NCS also raises awareness of corrosion problems and methods of control. For more information on NCS services and products please The review of international research in corrosion and corrosion protection of various metals and alloys is per-formed. Most of the foreign investigations are using accelerated corrosion testing and electrochemical methods. A few works are dedicated to mathematical modelling of degradation (a) Galvanic Corrosion (b) Pitting Corrosion (c) Stress Corrosion (d) Crevice Corrosion (e) Erosion Corrosion (f) Soil Corrosion (g) Micro-biological Corrosion (h) Water-line Corrosion (i) Differential aeration Corrosion (j) Intergranular corrosion. Corrosion and its Control | 5. Corrosion control and treatment are of vital concern because corrosion of equipment and primary structures has a great effect on the operational and structural integrity of systems. Economy is another basic consideration since severe corrosion will eventually weaken structural members to the point lated disasters, however, corrosion can be controlled, but at a cost. Corrosion Control Methods Various time-proven methods for preventing and controlling corrosion depend on the speci? c material to be protected; environmental concerns such as soil resistivity, humidity, and exposure to Definition of corrosion inhibitors: Corrosion inhibitors are substances that are added in small amount (e.g 0.1%) to the corrosive medium stop or slow down electrochemical corrosion reactions on a metal surface.

It becomes quite a challenge to control corrosion of the equipment without interfering with chemical processes. As corrosion and corrosion control are affected by both original design and construction and main-tenance, information is presented regarding all methods for reducing corrosion even though the information is primarily oriented toward maintenance and repair.
