Corrosion consulting aims to positively impact society by reducing corrosion effects, which can impact product quality, equipment life, safety, and the environment. The purpose is to offer expert corrosion consulting services to categorize corrosion issues, risks, and solutions by inspecting sites, determining failure causes, and providing materials selection guidance, training, and testimony.
This is a presentation on hydrogen induced cracking ,sulfide stress cracking and test procedure for HIC resistant steel

Mainly focused on how hydrogen will get trapped in the weld bead and how it will causes the embrittlement which sometimes leads to hydrogen induced cracking.
As an old adage says, corrosion prevention must start at the blackboard, at the design stage. A good design at the blackboard is no more costly than a bad design, a bad design is always more expensive than a good design in reality. Technical design inclu- des the aspects of design that directly bear on the proper technical functioning of the product attributes that describe how it works and how it is made. Design configuration has a critical role to play in the service life of components

As the oil and gas market moves towards new corrosion-resistant materials and alloys, specifying products has become increasingly complex.
When no single material performs well in every application, how can specifiers determine the best fit for a project? And what can be done to predict the expected service life of a component?
This technical seminar, run by Parker on its stand at the major oil and gas event Offshore Europe 2017, looks at:
• Common types of corrosion and their triggers
• Key factors to consider when selecting materials for a project
• Different manufacturer perspectives and the science behind their arguments
• Risks associated with mixing dissimilar materials.

There are many methods to prevent corrosion in all types of structures. Specifically in steel pipelines and metals. Chicago Corrosion Group has explained three main methods to prevent corrosion that are: coatings, corrosion inhibitors, and cathodic protection. To get complete details Click out the presentation.
INHIBITION OF CO2 CORROSION BY FORMATE FLUIDS IN HIGH TEMPERATURE ENVIRONMENTS John Downs
Presentation to the Royal Society of Chemistry's "Chemicals in the Oilfield" conference, November 2005
The paper describes how formate brines protect steels against CO2 corrosion. It also shows the results of stress corrosion cracking tests on CRA steel samples exposed to high-density completion brines containing oxygen at 160 deg C. The 13Cr, 22Cr and 25Cr steels all cracked in the presence of calcium bromide brine containing oxygen.

ABSTRACT:
Small amounts of hydrogen can sometimes cause embrittlement of high strength alloys. Because of their technological and economic relevance, intense research is underway worldwide to improve our understanding of such phenomena.
A physical model has been used to study hydrogen behaviour during manufacturing of metallic alloys. In particular, the present model contemplates diffusion in its most comprehensive description, i.e., atom diffusion being driven by the gradient in chemical activation, instead of simply occurring down a composition gradient. The model incorporates as well the influence of thermal history, microstructure, matrix solubility, multiple trapping distributions, and interaction with the atmosphere.
Using this model is possible to describe and predict the behaviour of hydrogen in metals during real industrial processes. For instance, it explains the effect on hydrogen redistribution of parameters like treatment conditions, component size and microstructure, phase transformation temperature, grain size, carbide distribution, deformation level, etc.
Furthermore, a set of criteria have been developed to anticipate defect formation and embrittlement risk, based on hydrogen supersaturation.
Last but not least, a method has been developed during this work, which enables to reduce hydrogen content from the metal via the use of imposed temperature gradients. This method has recently obtained several patents.
During this presentation, Amol Vaidya, senior engineer, global materials characterization and modeling, shares research findings that Owens Corning's Advantex® glass fiber reinforced polymer (E-CR-Glass) provides longer service life and cost savings in corrosive environments, compared to stainless steel and E-glass-based FRP. Corrosion is an economic and environmental issue the oil and gas industry has faced for years, typically addressed with high-cost metal alloys or various coating technologies. Glass fiber reinforced polymer composites can be an effective, low-cost alternative to these expensive alloys.
TRADITIONAL ingots vs. REMELTED, Comparing Metallurgical ResultsASO Group
As everyone know, remelted ingots are, from a purely metallurgical point of view, preferable to the traditional bottom poured ingots because of a series of reason:
chemical homogeneity
micro inclusions content
ultrasonic results test
absence of segregation
fine and uniform structure.
For a better understanding, we compared characteristics of a remelted ingot around 40tons, with a poly ingot with a similar traversal section of 1500mm and a gross weight near 32tons.
