Abstract (en)
[origin: EP0411293A2] The gulley essentially consists of a pot (10) made of plastic, having a pressure pipe (20) and a bell (23) as elements for the odour seal, which are likewise produced from plastic. As protection against chemical effluents, the pot is lined with a sheet metal cylinder (16) made of special steel. The pressure pipe (20) is inserted detachably into a pipe connection (19) of the sheet metal cylinder. In the edge region of the pot, the protection against chemical effluents is provided by a detachably clamped ring (30) made of special steel, which, as a result of its mechanical forces, provides the welded-on bitumen web (1) with an additional hold. <IMAGE>
