发明名称 MAKING PIPE FOR LIQUID CONVEYANCE
摘要 The invention relates to an apparatus for making a multilayer composite pipe. The multilayer composite pipe comprises an innermost layer (2) made of plastic. The pipe has a seamless metal layer (4) or a metal layer (4) having an axial, non-overlapping seam. The outer surface of the metal layer is treated for changing its outer appearance. There-after a transparent outermost layer (8) is provided on the outer surface of the metal layer.
