<p>The heating element (1) has a tubular hollow body made of metal. The hollow body has one or more grooves (3,4) with inserted or pressed tubular heaters in its outer and inner lateral surfaces. A filling injector (9) is fixed in a groove shaped recess of a tubular wall section (20) in heat transferable manner. The tubular wall section is separated thermally from the pipe wall by two front sided notches and is radially attached to a nozzle body by a radial contact force staying in laminar thermal contact in gap-free manner.</p> |
