The presentation will discuss the challenges, overall objective and unique characteristics of the viscous-elastic semi-solid compound and bolt cap protection system. Testing, installation procedures and previous projects will be covered. One of the projects to be covered is the system used to protect the support rods of the recently constructed San Francisco Bay Bridge connecting Oakland to San Francisco. The bridge made the news prior to opening when it was determined that a portion of the support rods were experiencing fatigue and showing signs of premature failure.
Have you ever wondered about the huge amount of money you spend in abrasives, logistics, recovery and cleaning of abrasives and the great amount of resources used during a project in the stage of surface preparation when you have a project for Maintenance of Storage Tanks? well, with this presentation you will learn about a great new technology available in the American market for this specific activity.
Traditional zinc rich primers are the primer of choice during new construction of assets placed offshore for oil & gas production. However, during maintenance, zinc rich primers are not used because of difficulties of having good surface preparation and controlling applied dft to prevent cracking. This paper will examine the performance of new, activated zinc rich epoxy primers compared to conventional zinc rich epoxy primers on steel prepared to different surface profiles using standard techniques of today.
