Abstract: The pipe-cleaning attachment is a kit. The pipe-cleaning attachment is configured for use with a copper pipe. The pipe-cleaning attachment is a tool that cleans the interior surface and the exterior surface of the copper pipe in preparation for processing. By processing is meant one of several plumbing procedures including, but not limited to, soldering the copper pipe or cutting the copper pipe. The pipe-cleaning attachment is an electrically powered rotating brush that physically cleans the copper pipe. The pipe-cleaning attachment comprises a plurality of cleaning kits and a drive system. The plurality of cleaning kits comprises a collection of brushes. The drive system rotates a brush selected from the plurality of cleaning kits to clean the copper pipe.

Abstract: A metallized uniaxially heat-shrinkable, biaxially oriented, multilayer film having a polypropylene-containing core layer comprising at least 70 wt. % of said multilayer film and at least one polyolefin-containing skin layer adjacent said core layer is prepared by biaxially orienting a coextrudate and thereafter orienting said coextrudate by stretching 10 to 40% in the machine direction. The core layer contains isotactic polypropylene and a modifier which reduces the crystallinity of the polypropylene by increasing chain imperfections or reducing isotacticity of the polypropylene-containing core. Such modifiers can be selected from the group consisting of atactic polypropylene, syndiotactic polypropylene, ethylene-propylene copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 terpolymer, and linear low density polyethylene. The skin layer can be high density polyethylene or ethylene-propylene-butene-1 terpolymer.
