When a coating disbonds from a structure and prevents cathodic protection (CP) from reaching the metal surface, this is known as “shielding” behavior by the coating. Shielding is a serious issue that has been a contributing cause for several pipeline failures, and expensive replacement programs. There are many factors (Soil resistance, holidays, coating resistance, etc.) that determine whether the coating will behave this way. Federal regulations for transmission gas pipelines require the use of a non-shielding coating.

This paper will discuss both the advantages and disadvantages from a variety of viewpoints of specifically UHP Robotics when used to prepare a previously coated carbon steel storage tank for coatings. Interviews have been conducted with UHP Business Owners/Operators, Painting Contractors, Facility Owner Representatives, Coatings Inspectors and Coatings Manufactures to obtain a broad view of the use of the technology.
Successful digitalization can improve process efficiency, provide deeper insight into operations, and greatly simplify compliance. This presentation will outline how Champion Painting, a global industrial painting contractor, uses the TruQC digitalization platform in its daily operation.
Aromatic polyurethane coatings are often used in the protection of steel water pipelines from corrosion. Unfortunately, pipeline sections may be stored above ground for many months before installation so the coatings yellow, lose gloss and can chalk. This deterioration in appearance naturally creates doubt about the corrosion protective qualities of the coatings.
The intent of this presentation will be to briefly analyze the evolution of the steel surface preparation market by focusing on three common methods for steel surface preparation used today (i.e., dry abrasive blasting, wet abrasive blasting and ultra-high-pressure blasting (UHP)) and the effects of water and additives on cleanliness, degree of surface preparation, coating integrity and coating adhesion. This presentation will include test results comparing the effects and results of different forms of surface preparation and the resulting coating application characteristics.
This paper will outline the results of using CNTs in liquid applied coatings, resulting in the elimination of secondary surface preparation steps such as grinding, chamfering, and rounding of edges as well as eliminating the need to apply a stripe coat. The overall impact realized from the elimination of these process steps include, increased productivity, increased throughput, improved edge coating performance, and substantial lowering of project costs.
For corrosion engineers to take Nondestructive Testing (NDT) measurements at height, currently they may need to utilize a lift, scaffolding, ladders, inspection trucks with elevated baskets, rope work, catwalks, cranes and rigging or other solutions. NDT inspection programs can dramatically increase the safety and integrity of infrastructure, industrial and manufacturing assets, access requirements in performing these inspections introduces risk.
Protective coatings based on waterborne acrylic technology have been used in the design, construction and maintenance of commercial and industrial structures for over four decades, and the types of applications where they are used, their formulation, and performance have evolved during that time period. Driven by the ability to meet environmental regulations, their ease of use, and improvements in performance, the utilization of waterborne acrylics has also grown over the years.
A The white paper titled “The Rebranding of a Safety Culture” presented at the 2019 SSPC Coatings+ Conference introduced the concept of managing the process of rebranding a safety culture. Leadership Commitment and Practicing Accountability are significant components to the rebranding process.
Today I am going to share results from a research project on Throughput Optimization (TPO). The focus of which was on a small subset of innovation variables in the overall workflow of a tank fabrication company servicing the oil and gas market. The data subset is based exclusively on protective coatings for the interior and exterior of API 12 Production Storage Tanks.
A common frustration in our industry is the project submittal process. Engineers, Consultants, owners and manufactures are frustrated by the process. How do you really know what products are right for your project? Data from recent studies show that projects where two or more manufacturers’ products are specified, results in overall project savings of 23% or more. This demands a closer look at the selection and specification process.
Surface preparation techniques have evolved with the acceptance of UHP waterjetting (UHP WJ). The new technique has proven to provide benefits in not only workflow, but also in the overall project’s pocketbook as well. With quality requirements rising and budgets for maintenance activities decreasing, UHP WJ has become the ideal surface preparation solution.
