PRESSURE VESSEL AND HIGH-PRESSURE PRESS

摘要

The present invention relates to a pressure vessel and a pressing arrangement comprising such a pressure vessel, for use at high-pressure pressing. The pressure vessel comprises a pressure chamber arranged for accommodating a pressure medium is provided. The pressure vessel comprises one or several cylinder segment/segments arranged to form a pressure vessel cylinder surrounding the pressure chamber, whereby a joint is formed at adjacent longitudinal edges of the cylinder segment/ segments. Prestressing means are provided around an outer envelope surface of the pressure vessel cylinder for radially prestressing the pressure vessel cylinder. Each joint at adjacent edges of the cylinder segment or segments has a continuous extension along the longitudinal length of the pressure vessel cylinder.
