FIELD: machine building.
SUBSTANCE: invention refers to a method for reduction of adhesion of gas hydrates to inner surface of a path and associated equipment, which transport or process fluid flow at explorations and production of oil and gas, in oil refining and/or petrochemistry, resulting in provision of inner surface of the path with a layer of the coating, which is characterised by static contact angle of wetting for the resting water drop on the coating layer, in the air, which is more than 75°, under ambient conditions according to the measurement in compliance with ASTM D7334-08, where the above coating layer includes diamond-like carbon (DLC) containing fractions of one or more components chosen from the group consisting of silicon (Si), oxygen (O) and fluorine (F).
EFFECT: preventing hydrate blocking of a natural gas transporting pipeline without any need for deterioration of tightness of the pipeline structure.
