Claim:
1. A polypropylene composition suitable for pipe applications comprising: a propylene random copolymer (A) with at least one comonomer selected from alpha-olefins with 2 or 4 to 8 carbon atoms, wherein the polypropylene random copolymer (A) comprises at least a propylene random copolymer having a low molecular weight (low molecular weight (LMW) fraction) and a propylene random copolymer having a high molecular weight (high molecular weight (HMW fraction), wherein the weight average molecular weight of the low molecular weight fraction is lower than that of the high molecular weight fraction; and a nucleating agent (B); wherein the polypropylene composition has a polydispersity index (PI) of from 2.0 to 7.0, a melt flow rate MFR
