PACKING COMPONENT Russian patent published in 1997 - IPC

FIELD: heat-exchange apparatuses. SUBSTANCE: the packing uses a flat cylindrically bent metal band. The metal band should be of a relatively small thickness and be ready to perceive the pressure forces arising in reactors without any strain, and provide for stamping and bending in the conditions of mass production. At least one fastener is placed on the side end sections of the metal band adjoining each other, the fastener has minimum one lug and spline that are made as a kinematically coupled pair, and the end sections have a movable joint with each other by means of the fastener in an annular bent state of the cylindrical component of the packing, and are protected against a relative shift with respect each other decreasing the ring circumference. EFFECT: enhanced effective surface of heat-exchange apparatus. 8 cl, 5 dwg
