Corrosion in metallic industrial equipment, pipework, and vessels, when left unchecked, can lead to the full deterioration of wall-thickness. The presence of through-wall defects may lead to loss of production and costly shutdowns, in addition to environmental and safety hazards. One solution to this issue is the installation of a repair system using composite materials, which are durable for decades, easy to install, and a cost-effective to deploy option for bringing industrial equipment back to operation, even after a leak is detected. Internationally recognized organizations, such as ASME and ISO, set the rules for the design methodology, material testing, and training of personnel for this type of repair method.

Corrosion costs the US Department of Defense billions of dollars annually, with the impact of corrosion estimated at $20.6B in fiscal year 2016. It continues to be one of the leading causes of aircraft unavailability and accounts for a significant portion of maintenance labor and costs. Corrosion management practices are chosen to minimize maintenance costs while maximizing the availability of an asset.
This presentation will offer best practices maintenance advice to the user of Abrasive Blasting Equipment, providing a ready-made checklist to guide the user through an operating year.
As an island nation, Japan is particularly dependent on the good health of its bridges to connect its different regions for commercial activities. In order to reduce maintenance cost and downtime for bridges, Japanese road authorities have looked to the use of longer lasting premium materials of construction.
A well-maintained CIP Evaluation and Rehabilitation program can save millions of dollars in replacement cost!
A cathodic protection (CP) system reduces corrosion by minimizing the difference in potential between the anode and the cathode. This reduction can be achieved by applying a current to the structure to be protected from an electrical source. When enough current is applied, the whole structure will be at one potential, thus anode and cathode sites will not exist. CP is commonly used on many types of structures, such as pipelines and underground storage tanks.The paper is about an effort to improve Southern Area Gas Producing Facilities’ (SAGPF’s) CP system in compliance with all related Saudi Aramco standards, procedures, and GIs, and provides in depth analysis and recommendations to mitigate CP system challenges, and to make CP system reliable. In addition, the study aims to identify key tasks to minimize the effect of component failures and to increase the reliability of SAGPF remote monitoring units, to get accurate data. The onsite CP system survey was performed from April 26 to September 30, 2018, for all SAGPF. This paper is focused on the major challenges, such as equipment failures, operational deficiencies, and technical recommendations to make the CP system efficient and reliable.
In 2002 NACE International published a cost of corrosion study backed by the U. S. Federal Highway and Safety Administration estimating the annual cost of corrosion in the U. S. to be $276 billion. In the more detailed breakdown of these costs by industry/market segment the cost associated with the water and wastewater utilities segment in the “Utilities” category was estimated at $36 billion. The water and wastewater utilities segment represented the single largest cost segment in the study. The $36 billion estimate for this single segment of the Utilities category represented more cost than any of the other four categories: Transportation, Infrastructure, Government, and Manufacturing & Production.
Concrete is an inherently attractive building material. It expresses the natural appeal of stone by its mass and permanence. With the addition of natural looking color variations, concrete as stone, is even more realistic. Concrete stains are an excellent choice for producing colors often found in earth and rock. When combined with simple and creative application techniques, stains allow for truly unique concrete installations, which complement a variety of hardscape and flooring designs.
The paper will cover the construction method (based on Random forest algorithms), the first results. We will see the enhancements of the model by injecting more data and modifying mathematical rule, and how it will be able to integrate a new decision support tool.
To develop a Maintenance Coating Program encompassing cost justification for projects, pre-planning evaluation of safety and quality assurance programs. From two previous NACE Conference Papers.
Consistent coating inspections and planned maintenance are essential to asset integrity. Non-existent, delayed, and cursory inspections can allow premature coating breakdown, corrosion, and costly failures. On the other hand, improper maintenance can be ineffective, costly, and wasteful. The challenge involved in executing informative inspections and effective maintenance practices is identifying and understanding the numerous conditions that can contribute to a reduction in the lifecycle of an asset. This paper will discuss some of the aspects involved in identifying coating conditions that are likely to result in failures and developing cost effective coating repair strategies that will extend the life of the asset.
