    Abstract: The invention relates to a pipe comprising polyethylene or a polyethylene composition comprising polyethylene and carbon black, wherein the polyethylene is produced in the presence of a solid catalyst component and a co-catalyst, wherein the solid catalyst component is prepared by a process comprising the steps of: (a) contacting a dehydrated support having hydroxyl groups with a magnesium compound having the general formula MgR 1 R 2 , wherein R 1 and R 2 are the same or different and are independently selected from the group comprising an alkyl group, alkenyl group, alkadienyl group, aryl group, alkaryl group, alkenylaryl group and alkadienylaryl group; (b) contacting the product obtained in step (a) with modifying compounds (A), (B) and (C), wherein: (A) is at least one compound selected from the group consisting of carboxylic acid, carboxylic acid ester, ketone, acyl halide, aldehyde and alcohol; (B) is a compound having the general formula R 11 f(R 12 O) g SiX h , wherein f, g and h are each integers from 0 to 4 and the sum of f, g and h is equal to 4 with a proviso that when h is equal to 4 then modifying compound (A) is not an alcohol, Si is a silicon atom, O is an oxygen atom, X is a halide atom and R 11 and R 12 are the same or different and are independently selected from the group comprising an alkyl group, alkenyl group, alkadienyl group, aryl group, alkaryl group, alkenylaryl group and alkadienylaryl group; (C) is a compound having the general formula (R 13 O) 4 M, wherein M is a titanium atom, a zirconium atom or a vanadium atom, O is an oxygen atom and R 13 is selected from the group comprising an alkyl group, alkenyl group, alkadienyl group, aryl group, alkaryl group, alkenylaryl group and alkadienylaryl group; and (c) contacting the product obtained in step (b) with a titanium halide compound having the general formula TiX 4 , wherein Ti is a titanium atom and X is a halide atom, whereby the polyethylene has a molecular weight Mz+1 of at least 720,000 g/mol and less than 2,500,000 g/mol.
