Water transport through epoxy-based powder pipeline coatings

The water permeation kinetics of two common epoxy-based powder coating systems for pipelines across a range of industrially-relevant temperatures (from room temperature to 80 °C) has been studied. The nonlinear dependency of water transport on the vapour concentration at 65 °C was also analysed. The vapour transport analysis of epoxy coatings demonstrated a turning point around this temperature, perhaps due to clustering of water molecules. At higher temperatures, break-up of water clusters and plasticisation of the polymer expedited the transport.

The researchers also examined microstructural changes of the epoxy network due to water transport and found evidence for irreversible damage to epoxy coatings under hydrothermal exposures. It appears that the combination of thermal exposure and internal stresses in the glassy epoxy leads to a phase separation of filler particles from the epoxy matrix, as well as to a distinctive cavity formation in the coating membrane. The results indicate that hydrothermal exposure is likely to increase aggregate porosity of the coating. Analysis of wet-state permeation is not only crucial for protection of transport pipelines, but it also is of high relevance to process equipment and underground storage tanks.

The study was published in Progress in Organic Coatings, Volume 168, July 2022.

Optimisation of adhesion to improve steel corrosion protection

Optimisation of adhesion to improve steel corrosion protection

A new study focused on the possibility of using siloxane resins with epoxy modification to delay corrosion of metal substrates for hydraulic applications.

Formulations aimed at metal protection were designed, without including anticorrosive additives, and deposited on 11SMnPb37 steel. Thin monolayer films were obtained by dip coating in different process conditions, avoiding primers. The developed procedure was simple and able to provide solid and well-anchored coatings. They were characterised in terms of morphology, scratch and wear endurance, and resistance to a corrosive environment. The optimum formulation and deposition parameters were determined and the selected coating showed remarkable adhesion to the substrate, good mechanical properties, and resistance in a saline environment, proving to be suitable as a protective barrier against corrosion. The protective effect was ensured not by additives but through the excellent adhesion of the coating and its endurance to scratch and wear.

Universal Primer

Global liquid and powder coatings supplier Axalta, has recently launched what it calls the first premium universal thermosetting powder primer available in the world. Alesta ZeroZinc UniPrime has been released in the EMEA region and is available from local Axalta offices.

According to the company, like other products in the Alesta ZeroZinc range, UniPrime has been formulated in accordance with High Density Ccrosslinking technology to prevent corrosion and extend a painted structure’s working life. The epoxy resin-formulated primer is reportedly easy to apply and meets stringent anti-corrosion requirements.

ZeroZinc UniPrime can be applied to all types of substrates, including steel, hot dig galvanized steel, metallised steel, aluminum, etc. It can also cover hard-to-reach places and demanding shapes, such as expanded metal, perforated sheet steel and sharp edges, concluded the company.

New ICorr MIC Training Course Available

New ICorr MIC Training Course Available

The Institute of Corrosion (ICorr) is delighted to offer the Microbiologically Influenced Corrosion (MIC) training course to meet the increasing demand from industry.

MIC is the least understood phenomenon of corrosion despite it has been identified as the prime cause of a number of high-profile failures around the world with devastating effect on health and safety, reliability and finance of operations, company reputation and the environment.  It is estimated that 20% of all corrosion failures are primarily due to the metabolic activities of microorganisms in industrial systems. This amounts to an estimated annual cost of USD 2.5 billion to the oil and gas industry.

The state-of-the art course provides expert knowledge on MIC threat, identification, and mitigation technologies.  The last over three decades of research and hand-on field experience, provided in depth understanding of industrial and oilfield microbiology. The introduction of molecular microbiology methods to industry enhanced microbial characterisation and the development of more effective monitoring and prevention techniques.

The course uses case studies to share best practices to control the spiraling MIC and associated microbial colonisation cases in different natural and industrial systems around the globe. Microbes colonise systems with traces of water leading to detrimental effect on most industries including oil and gas, water treatment and filtration/reverse osmosis, infrastructure including accelerate low water corrosion (ALWC), heat exchangers and cooling systems, paper industry, and nuclear energy.  It also addresses future trends regarding the development of effective modelling to better predict MIC and to ensure targeted treatment.

The course covers both theoretical and practical aspects of MIC and is offered in three formats to meet the demand of various industries at different levels of proficiency as follows:

Proficiency level Certified MIC Technologist

A five-day course covering theoretical and practical sessions with a focus on providing detailed knowledge on handling and developing a MIC control program including setting sampling and monitoring strategies, data interpretation and presentation and identification of potential risks. This course includes a half day for taking a certification exam paper on the last day.

An ICorr Certified MIC Technologist certificate is provided on passing the exam.

MIC Technologist

A four-day course similar to the Certified MIC Technologist course but without the certification exam on the last day.

A certificate of attendance is awarded.

 

Awareness Level

A one-day course providing an overview of the MIC phenomenon with a focus on comprehending and managing MIC.  It is designed for managers and stake holders wanting to understand the risks and mechanisms to ensure cost avoidance but are not MIC practitioners.

A certificate of attendance is awarded

 

· Who should attend

The course will be of considerable benefit to managers, consultants, project leaders, industrial biologists, corrosion technologists, engineers, scientists, students, contractors, field management and technical staff.

 

· Cost of the course

The fee for the one-day course is GBP £800 +VAT and for the four-day course is GBP £2,000 +VAT.  For those wishing to take the exam after the four-day course there is an additional cost of GBP £500 +VAT. (VAT is reclaimable by VAT registered companies).

These costs are based on attending the course in the UK.

 

The Institute of Corrosion is happy to discuss your needs and to deliver the course either at;

  • ICorr headquarter in the United Kingdom, or
  • Your premises around the world.

The course is delivered by Dr. Tony Rizk, a world-renowned expert with many years of practical experience.

Currently, the course is available only in a classroom format, although an on-line format will be developed in the future.

To help us plan the initial availability of this long-awaited course we would appreciate feedback on your interest as follows:

I am interested:

  1. The ICorr Certified MIC Technologist course (including certification exam) in the UK
  2. The four-day course in the UK
  3. The one-day course in the UK.
  4. Discussing the option to bring the course to a location of your choosing.
  5. Other feedback
