Abstract
The present invention relates to a method for reducing gas hydrate adhesion to the interior surface of a conduit and associated equipment transporting or processing a fluid stream in oil and gas exploration and production, petroleum refining and/or petrochemistry, by providing the conduit interior surface with a coating layer exhibiting a static contact angle of the sessile water drop on the coating layer in air higher than 75° at ambient air conditions, as measured according to ASTM D7334-08, wherein said coating layer comprises diamond like carbon (DLC) comprising fractions of one or more components selected from the group consisting of silicon (Si), oxygen (O) and fluor (F).
