INNER SURFACE COATING FOR OILTANKING FINLAND’S CONTAINER

In early October, FSP gave Oiltanking Finland’s raw turpentine container a new inner surface coating. The container is 16 metres high and its diameter is 11 metres. The demanding project was carried out in the Mussalo Container Terminal in Southern Finland, and the FSP project staff included Supervisor Karri Lempinen and surface treatment veterans Ari and Kai Kuusisto.

“Raw turpentine is a very strong chemical, and the container had to be ventilated for four weeks before starting surface treatment work on the inner surface.

Scaffoldings were build inside the container, and then the surface was sand blasted and cleaned. After the customer inspected and approved the pre-treatment work, we gave the container a zinc silicate coating,” explains Lempinen.

Industrial containers are given a new surface coating every 5–10 years to maintain adequate corrosion resistance and tightness. Zinc silicate is well suited for containers that are used to store extremely corrosive materials. Its properties include, among others, resistance to high temperatures – even 600 degrees Celsius – and resistance to abrasion and solvents.
