An inclined separator for separating oil well substances is provided comprising an elongated outer, closed tubular section and an elongated, inner tubular section arranged inside the elongated outer tubular section, where both the elongated outer, closed tubular section and the elongated, inner tubular section are inclined either upwards or downwards relative to horizontal. The elongated, inner tubular section is closed in one end by an end cap, working as a slug breaker, and open in another end for connection to a tube feed section via a conical expansion between the tube feed section and the inner tube section. Oil well substances are introduced into the open end of the inner tubular section via the tube feed section passing through the outer tubular section and into the inner tubular section. The inclination of the separator facilitates separation of the oil well substances into lower density substances and higher density substances.
