Type of Structure(s):
Existing steel outfall and inlet pipeline located within OCSD’s pump stations and surge towers.
Condition of Structure(s):
The existing 120-inch steel ocean outfall was constructed in the late 1960’s and began operation in the 1970’s. During an inspection in 2010, it was determined that significant corrosion had degraded the suction and discharge piping of the ocean outfall segment between the Ocean Outfall Booster Station and the surge tower.
Description of Application:
Raven 405 was selected for the project because of its 50-year design life and high physical strength. The project specification called for removal of the existing coal tar epoxy and cleaning the steel to meet SSPC SP-10/NACE No.2 standard. A minimum of 60 mils dry film thickness of Raven 405 was then applied to the prepared steel by Murphy Industrial Coatings. The coating system was tested to ensure a holiday free and monolithic coating existed. Adhesion testing was also performed to confirm the adhesion of the coating to the steel substrate.
