#CMT# #/CMT# The pipe (2) for transporting drinkable water, comprises a spheroidal graphite cast iron base body (8) defining an external surface (10) and an internal surface (12), and an internal coating (14) applied on the internal surface of the base body. The internal coating is made up of a thermoplastic material and an acrylic material. The base body has a wall thickness lower than 4 mm. The internal surface of the base body is obtained by hammering. #CMT# : #/CMT# An independent claim is included for a process of fabricating a pipe. #CMT#USE : #/CMT# The pipe is useful for transporting drinkable water. #CMT#ADVANTAGE : #/CMT# The pipe can be easily and economically manufactured with smooth inner surface and with good adherence and resistance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a longitudinal cross section of a finished pipe. 2 : Pipe 8 : Base body 10 : External surface 12 : Internal surface 14 : Internal coating. #CMT#POLYMERS : #/CMT# Preferred Components: The thermoplastic material comprises a base of polyolefin or polyamide. |
