Abstract

The present invention relates to a calibration device for use in a process of making a tubular article comprising a housing (200) and a calibration sleeve (300) providing a vertical pass-way for an extruded tubular extrudate, the housing comprising a bore (210), an upper opening with an upper seal (280)and a lower opening with a lower seal (285); a vacuum channel (215) connecting the bore to a vacuum source; a liquid channel (255) for receiving a flow of liquid and connecting to a reservoir (250) on top of the housing; and an adjustment device (265) for controlling the liquid level in the reservoir; and the calibration sleeve (300) comprising a body with multiple apertures (340) and an inlet flange (330); the calibration sleeve (300) removably positioned in the bore (210) and contacting the housing (200) via the upper (280) and lower (285) seals. This calibration device enables making a tubular article in a very flexible way, specifically on small scale in the laboratory; and can be operated in free or contact calibration mode, both with either dry or wet operation. The invention further relates to an extrusion system for making tubular articles from a polymer composition comprising such calibration device, and to a process applying such device or system.
