Abstract

The pipe has an outer shell made up of lead and an inner covering coated with paraffin. A mixture of alkanes having chemical formula CnH(2n+2) is distributed by blowing, aspiration or gravity on inner walls of the pipe. The mixture has multiple carbon atoms greater than 15 in their chemical composition, like paraffin. The mixture is vaporized or pulverized in the form of aerosol. An independent claim is also included for a method of fabricating a drinking water distribution pipe.
