Abstract
The present invention relates to a system for fastening and sealing the flanges of the inlets of pressure vessels operating under extreme temperature conditions and with frequent opening/closing cycles, as is the case of coking vessels (5), consisting of an assembly of a flange of the tongue (1) and groove (2) type, a C-clamp (3), and a soft compression gasket (4). Such a system offers total remote control of the opening of the vessel inlets, resulting in greater safety, less unit downtime, and lower operating costs. The invention also relates to a method for opening inlets which results therefrom.
Claims6
A system for rapid opening of coking vessels under extreme temperature conditions, comprising an assembly for connection of flanges by means of a clamp which has been improved for frequent use, comprising a tongue-type flange (1) and a groove-type flange (2), a C-clamp-type fastening clamp (3) and a non-metallic compression gasket (4) designed to be placed at the interface of the flanges so as to promote sealing of the system.
A method for rapid opening of coking vessels under extreme temperature conditions and with frequent use, comprising releasing, by remote control, the C-clamp-type fastening clamp which connects the flanges of the inlets of the pressure vessel, thereby changing the vessel from the closed state to the open state;
- and then disconnecting the external flanges and detaching them from the pressure vessel.
