Every Jotun product is the result of intensive research and development combining state-of-the-art technology with innovative thinking, practical knowledge and experience, says the Norwegian company.
Protection of petrochemical plants, refineries and other chemical industry structures present the coatings manufacturer with some of the most challenging demands in advanced technology for protection against corrosion, it says.
The structures are exposed to aggressive attack from climatic, chemical and mechanical influences. It is essential that a corrosion protection system is selected with care to ensure it meets three specific demands: resistance to the penetration of corrosive substances extremely good adhesion resistance to chemical, mechanical and thermal stress.
The design and construction vary from plant to plant depending on size, production type, what is manufactured, location of site, etc. In the petrochemical industry, for example, plant often has to withstand high temperatures and operate under high pressure.
Pipes, together with their supports and valves often represent problem areas where corrosion can develop.
Large storage tanks are visible and dominating, therefore the best exterior corrosion protection together with a long lasting topcoat is vital for the plants appearance.
Access (staging) is costly, consequently maintenance intervals should be as long as possible. Topcoat colour should be white or near white as this will prevent heat absorption. Good looking tanks represent good publicity for the owner, it says.
The environment is always tough. Installations are often situated in coastal areas and the mixture of marine and industrial atmosphere produces a highly corrosive condition.
After the plant is built and production has started, maintenance may often be difficult. In many areas blast cleaning is forbidden without production shut down, which will lead to loss of income and increased cost.
To avoid such problems Jotun is the right partner when it comes to writing a coating specification and planning the actual coating work.
The correct products will be recommended, supported by chemical resistance list and references.
Technical service provided by personnel certified to Frosio or NACE certification standard will ensure correct surface pretreatment and paint application in order to secure long life corrosion protection where maintenance is reduced to a minimum.
The protective system should never be chosen on the basis of cost alone. Any savings in the initial cost will, in virtually every case, be more than offset by the cost of expensive maintenance, shut-down, or worse, should the structure present a safety hazard.
