From urethane foam removal to salt control and painting – Borealis’ propene container is renewed

Borealis is a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers. The company operates in 120 countries. In Finland, Borealis Polymers Oy manufactures polyolefins and base chemicals in Kilpilahti, Porvoo.

The unit is the largest oil refining and chemical industry facility in the Nordic countries. FSP provides year-round maintenance painting and surface treatment for the buildings and production facilities as part of a multiyear comprehensive service contract.

Next on the work schedule is the maintenance of Borealis’ propene container. It now has a urethane foam insulation. Once that is removed, FSP performs surface treatment for the entire silo and its attached pipes. There is circa 3000 m2 (29,000 sq. ft.) of total surface area to be treated in about five weeks’ time.

After the insulation is removed, the container is cleaned by shot blasting. After shot blasting, a salt control is carried out on the surface to ensure that it is ready for surface treatment. If there are salts on the surface prior to treatment, the surface may suffer corrosion damage after one year, at worst.

In addition to the container project, this year we will also paint a new long pipeline that Borealis is constructing along with a new repository. The pipeline is over 7 km long and runs from the repository to the harbour.

Our other works in Kilpilahti include fireproofing coatings.
