Abstract: The invention relates to a pipe comprising a polypropylene composition (P) comprising a terpolymer composition (A), a nucleating agent (B) and optionally a composition comprising pigment (C), wherein the terpolymer composition (A) comprises at least one terpolymer prepared from propylene, ethylene and 1-hexene, wherein the nucleating agent (B) is a nucleating agent comprising a metal salt of hexahydrophthalic acid represented by formula (I) (I) wherein M1 and M2 are the same or different, and may be combined into one cation, and are selected from at least one metal cation of calcium, strontium, lithium, and monobasic aluminum; and wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 are either the same or different and are individually selected from the group consisting of hydrogen, C1-C9 alkyl, hydroxy, C1-C9alkoxy, C1-C9 alkyleneoxy, amine, and C1-C9 alkylamine, halogens, and phenyl wherein the polypropylene composition (P) has a melt flow rate in the range from 0.10 to 0.70 dg/min as determined by ISO1133-1:2011 at 230° C. and 2.16 kg.
