Most industries bear the brunt of the ‘rot’ simply because corrosion prevention usually does not find a significant part in the master plan of mega projects. Every corrosion is different and each industry needs a different plan to evade corrosion. Be a part of WorldofChemicals’ “Corrosion Technology Forum” on June 7 and 8 in Bengaluru. Connect with industry stalwarts as we discuss corrosion prevention opportunities in the four major industries across geographies.

Oil & Gas Industry / Refineries / Petrochemicals

Mitigating corrosion risk from exploration to production

Oil & gas pipelines, refineries and petrochemical plants face serious problems due to corrosion. Corrosion affects every aspect of exploration and production – from offshore rigs to casing to in and around the pipelines transporting crude oil & gas. The atmosphere and flow regimes of fluids in the pipes greatly influence the corrosion rate. Over the next five years, these industries have outlined major production and capacity, expansion plans. In such a case, it is advisable to adopt corrosion protection technology beforehand from a long term perspective.

Further, with the population growth and infrastructure expansion, decisions in terms of addressing pipeline corrosion need to be handled in an aggressive manner.

Combating corrosion in these industries is paramount since the economic loss can run into several billions of dollars.

As part of the conference, industry experts will discuss the various challenges and also touch upon the different corrosion protection methods and technology.

Automobiles

The roots of corrosion in vehicles

Upon finding a rust spot on your vehicle, your first concern might be about the impact on its exterior. This however, indicates a larger issue within the interior of the car — a structural weakening of the car’s metal frame and components. Corrosion is a widely encountered issue in the automotive industry. Automotive corrosion leads to loss of material leading to failure and breakdowns, dimensional inaccuracy, degradation of aesthetics, deterioration of mechanical properties and increase in maintenance cost. The causes of corrosion in vehicles can be traced back to the manufacturing stage as well as to environmental conditions on the road. 

Also, material selection during manufacturing of vehicles is important as it helps improve resistance to corrosion.

At the event, industry experts will discuss the various challenges and focus on the latest development in corrosion mechanisms to minimize the risk of corrosion. 

Aerospace

Controlling mid-air corrosion failures

Airframe problems associated with corrosion has troubled the aviation industry for decades. The metals that compose aircraft components are subject to several different forms of corrosion. This can lead to catastrophic failures if not detected and treated.

Compounding the problems associated with corrosion is the age factor. As a plane ages, it is repeatedly exposed to environments that accelerate the effects of corrosion.

Implementing corrosion-prevention measures in the design & manufacturing and selection of materials used to repair/upgrade planes, in conjunction with effective maintenance procedures, is the best insurance against corrosion-related failures. An investment in corrosion control technology is an investment in public safety, and it protects the industry’s bottom line.

Experts will provide insight into cutting-edge knowledge of the complex variables that combine to influence the corrosion that poses a threat to the aging fleets of aircraft.  

Infrastructure

Predicting corrosion – Enhancing safety from failing infrastructure

Corrosion has a huge economic and environmental impact on all kinds of infrastructure. The annual cost of corrosion in terms of Gross Domestic Product is approximately 3 to 4 percent and it is of no surprise that a large proportion of this cost relates to indirect or hidden costs, for example loss of containment of product, pollution remediation, loss of production, increased maintenance and litigation costs.

Although corrosion can impact concrete pavement performance, primary concern is with highway bridges and ancillary structures. Because of it, buildings and bridges can collapse, oil pipelines break and water sources become contaminated. 

It has been recognised that up to 25 percent of this cost can be saved by applying existing knowledge of the basic principles of corrosion science and engineering.

Our experts will discuss opportunities related to infrastructure corrosion such as better materials, cost-effective long-life preservation strategies and condition assessment.
