Beschreibung
Zusammenfassung:	The invention relates to a port comprising a disc made of a transparent or opaque nonmetallic material and a ring clamping the peripheral edge of the said disc and exerting a compressive stress on the said disc, characterised in that the adjacent edges of the disc and of the ring are free of peripheral chamfers and in that the thickness of the disc is at most equal to the width of the ring. Use in particular as viewing (inspection) ports in chemical reactors. L'invention concerne un hublot comprenant un disque en un matériau non métallique, transparent ou opaque et une bague enserrant le bord périphérique dudit disque et exerçant une contrainte de compression sur ledit disque, caractérisé en ce que les bords adjacents du disque et de la bague sont exempts de chanfreins périphériques et en ce que l'épaisseur du disque est au plus égale à la largeur de la bague. Utilisation notamment comme hublots de visée dans des réacteurs chimiques.
