Abstract:
1. A process comprising injection molding a coating of a propylene copolymer (I) onto the metallic surface of a connected portion of metallic pipes to form a re-insulated injection molded coating, the propylene copolymer (I) containing up to 50 wt % of units derived from at least one linear or branched alpha-olefin having from 2 to 10 carbon atoms other than propylene and having: (a) a melting temperature (Tpm) equal to or less than 160° C.; (b) a crystallization peak temperature (Tpc) of at least 100° C.; (c) a temperature difference, Tpm - Tpc, equal to or less than 55° C.; (d) a melt flow rate MFR (ISO1133, 230° C/2.16 Kg) ranging from 15 to 600 g/10min; and (e) a Mw/Mn of lower than 4.0,
