ABSTRACT:
A pipe fitting for a heatable piping of a SCR (“Selective Catalytic Reduction”) system presents a body defining a hydraulic connection to make flow an urea solution from/to such piping; the pipe fitting further presenting an electrical connection, which is provided with a first terminal connectable to an electrical power supply, and with a second terminal connectable to a heating element of the piping (9); the electrical connection being also provided with an electrical resistor embedded in the body of the pipe fitting, whose material is a polymeric base and is thermally conductive to heat up the urea solution when the electrical resistor is powered.
