The heat exchange pipe comprises screw grooves of depth h with pitch t and angle of inclination to the longitudinal axis of the pipe φ, with depressions and protrusions on the outer surface and corresponding protrusions with diameter d between them and depressions with diameter D between them on the inner surface, and both surfaces have the same profile. The pipe has an oval profile, the outer and inner surfaces of which form a helicoid.
The utility model relates to the field of energy and cryogenic engineering and can be used in heat exchange equipment in chemical, biotechnological, oil refining, food, heat power and other industries.
