Velocity Effects in Flow Induced Corrosion
CORROSION 1990, 1990Abstract Different mechano-chemical mechanisms account for the deterioration of materials under the action of flow. The appearance of power laws of the form CR=const·ua in specific ranges of flow velocity u is typical for corrosion/erosion systems; changes in the exponent 'a' indicating mechanistic alterations.

The Effects of Flow on Corrosion Inhibitor Performance
CORROSION 1995, 1995Abstract Corrosion tests using a flow loop and rotating cylinder electrode are used to select corrosion inhibitors for downhole and flowline application. The results show tests incorporating high flow rates and high shear stress levels will differentiate the performance of different inhibitor formulations.

Flow Accelerated Corrosion Testing Basics
CORROSION 2006, 2006Abstract Generally, there are two reasons for conducting flow accelerated corrosion tests. The first is to make a comparison of material performance or corrosion control methods, such as corrosion inhibition under high turbulence conditions.

Flow Accelerated Corrosion: The Entrance Effect
Volume 6: Materials and Fabrication, Parts A and B, 2008Flow-accelerated corrosion (FAC) is a degradation process that attacks carbon and low-alloy steels. The process has been studied extensively for the last thirty years. Nevertheless piping leaks and ruptures continue to occur. Recent fatal accidents at the Mihama nuclear station in Japan and at the Iatan fossil unit in Missouri demonstrate that plant ...

Flow Effects in Corrosion Inhibitor Selection
CORROSION 1995, 1995Abstract Laboratory test techniques have evaluated the performance of corrosion inhibitors in actual or simulated oil or hydrocarbon condensates under dynamic flow conditions. The corrosion inhibitor performance was dependent on fluid velocity.

Evaporator Failure Caused by Corrosion and Flow
CORROSION 2008, 2008Abstract This paper deals with three cases of boiler tube failure. 1). Flow assisted chelant corrosion was concepted as reason for inadmissible thinning of economizer tubes. There were discontinuous orange peel and extremely thin layer of iron oxides on those scalloped waterside.

Wear/corrosion sensing in flowing seawater [PDF]
, 2002 Pipework for cooling and firefighting purposes on naval vessels is typically, subject to corrosion by pumped seawater. Close to land, erosion by ingested sand also occurs. The expensive alloys presently used to resist corrosion do not resist erosion very well.

Analysis and Application of Flow-Induced Corrosion and Scour Corrosion in Gas Well
Advanced Materials Research, 2013For natural gas well, the corrosion generated by the flow in tubing and the flow through the control manifold and scour corrosion should be fully considered in gas well control prevention design. This paper presents the technology background, scour corrosion, flow-induced corrosion, application on calculation of in-tubing flow velocity for preventing ...
