In an aspect, a biaxially oriented pipe has a thickened end portion. The end portion has the same inner diameter as the biaxially oriented pipe and has a larger thickness than the biaxially oriented pipe. The end portion is made of the same thermoplastic polymer composition as the biaxially oriented pipe.

Biaxially oriented pipe with a thickened end portion

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 R, R, R, R, R, R, R, R, R, and Rare either the same or different and are individually selected from the group consisting of hydrogen, C-Calkyl, hydroxy, C1-C9alkoxy, C-Calkyleneoxy, amine, and C-Calkylamine, 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.
