Offshore

In the offshore industry, mechanical components are to a large extent in direct contact with aggressive substances, such as salt water. The combination of high temperatures and a very high relative humidity is destructive for components that are used in offshore. The risk of corrosion increases even further when these conditions are combined with small spaces (slit action, capillary action) where little oxygen can enter.

In order to guarantee proper protection of the coolers, two methods are used:

PTFE
PTFE (polytetrafluoroethylene, better known as Teflon®) is applicable to metals such as aluminum, steel, stainless steel, titanium and copper. But also on various plastics and glass. PTFE coating, has excellent nonstick properties and is resistant to high and low temperatures. This makes PTFE very versatile.

HERESITE
Heresite is a thermally conductive phenol burn-in coating with a very high chemical resistance. This will be burned into a multilayer system in a polymerization oven after blasting and coating on the metal. A muffle session in the oven follows each coat layer. The coating is diffusely sealed and cross linked cross-linked. The coating is done according to the Norsok M-501 standard.

The Norsok M-501 embraces requirements and guidelines for multiple paint systems and different applications, which both paint suppliers and applicators have to meet. The products to be used, pretreatment, preservation and inspections to be carried out are described herein.
