Corrosion inhibitors play a major role in the cost effective control of corrosion. Because of the toxic nature and high cost of chemicals plant extracts are currently used as inhibitors. In the current study, efforts are taken to study the role of seed extracts of Phaseolus aureus on corrosion of mild steel in 1M HCl by weight loss method and potentiodynamic polarization technique. The Potentio...

Due to the progress in Computed Tomography (CT) applied for dimensional control new fields in materials characterization are opened. Especially volume properties can be non-destructively and quantitatively analysed which are non-accessible by other methods. These possibilities are used to study time dependent properties of corrosion. As an example concrete cylinders with embedded steel bars as ...

In latest years, various techniques and chemicals have been used for the control of microbial influenced corrosion (MIC) of metals. The application of botanical-based biocides is one of the effective and practical techniques in the fight against MIC. In the present study, the role of aqueous extract of ginger (Zingiber officinale) (GIE) as green biocide to control MIC of mild steel 1010 (MS) in...

The objectives of this study were to investigate the corrosion behavior of conventional and self-ligating stainless steel brackets and the surface structural changes in response to salad dressing. Damon, In-Ovation,Smart clip, Discovery, OMNI and Masel brackets were all included in the study. For the control group, the brackets were placed in Petri dishes with Potassium Ferrocyanide (Fe [CN]6K4...

Internal corrosion is a common problem in pipelines transporting oil and gas containing corrosive components such as CO2 and H2S. In many mature oil wells, the water cut and CO2 content may reach high level which forms a suitable environment for initiation and growth of corrosion. To avoid the consequences of corrosion, process parameters should always be controlled within safe operating limits...

This study has investigated the solubility of inhibiting pigments and also the leaching behaviour of corrosion inhibitors from a polyester binder in an acid rain solution. This study has relevance to the control of cut-edge corrosion by inhibitor pigments, which are incorporated into the primer coatings of coil-coated architectural cladding. The concentrations of leachate solutions in tubes glu...

Cathodic protection (CP) has been successfully employed to protect steel-framed masonry buildings from corrosion related damage. When a CP system is installed to protect the structural members, other metallic items which are within the fabric of the structure but are not in direct electrical continuity may suffer from stray current interactions, resulting in accelerated corrosion of the discont...

L. SMITH Controlling corrosion in production tubing is essential for maintaining production and for preventing loss of well control. Materials for use downhole have to meet criteria for corrosion resistance and also mechanical requirements. The potential corrosion rate can be estimated and the risks of sulphide stress corrosion cracking assessed on the basis of the anticipated environmental con...

Corrosion is a random phenomenon which reduces the strength of pipeline systems over time. Continuous operation of such systems involves significant expenditures in inspection and maintenance. The costeffective safety management of pipeline systems involves finding the appropriate amount of resources to allocate to initial design and to inspection and maintenance activities, in order to keep ex...
