constructions of sealings of flange joints of large diameter, possibly in plants and apparatuses for operation at high temperature and pressure values. SUBSTANCE: flanged connector includes two flanges, mounting members, main and additional gaskets arranged between flanges. Gaskets are placed in the same level between end surfaces of flanges. Each gasket has three non-detachably joined annular layers; mean layer is made of expanded graphite; outer and inner layers are in the form of metallic rings. Height of graphite layer in gasket is more than height of metallic rings. EFFECT: enhanced reliability of sealing of flange joints. 7 cl, 1 dwg
