Claims (3)

An apparatus for producing a metal-plastic composite tube coated with a plastic material on an inner and outer surface, comprising: (i) a core pipe forming means 11 for extruding a core pipe 10 having a predetermined inner diameter using a plastic material; ) The polymer tape 3b is discharged from the core pipe forming means II using an aluminum tape 3a coated on the inner surface thereof. Aluminum tape lapping means 12 for wrapping the conveyed co-pipe 10 and iii) end contact of the aluminum tape 3a wrapped on the core pipe 10 by the aluminum tape wrapping means 12. Sealing portion 13, which comprises a sealing means 13 for forming a concentric aluminum tube on the outer surface of the core pipe 10, and (i) an extrusion means 14 for extruding a plastic material on the outer surface of the sealed aluminum tube. An apparatus for producing a metal-plastic composite tube. The core pipe forming means (11) according to claim 1, wherein the core pipe forming means (11) cools the conventional extruder (1) and the first water tank (2) while maintaining the constant inner diameter of the core pipe (10) discharged from the extruder (1). Apparatus for producing a metal-plastic composite tube, characterized in that consisting of. The aluminum tape wrapping means 12 simultaneously receives the core pipe 10 discharged through the first water tank 2 and the aluminum tape 3a conveyed from a separate roll 3, A hopper-shaped lapping die 5 surrounding the aluminum tape 3a on the outer surface of the core pipe 10, and a core in the composite of the core pipe 10 and the aluminum tape 3a passing through the lapping die 5 In order for the tape 3a to be closely adhered to the outer surface of the core pipe 10, a plurality of inner diameters are gradually reduced, so that a plurality of inner diameters have the same inner diameter as the outer diameter of the aluminum tape 3a wrapping the co-pipe 10. Apparatus for producing metal-plastic composite tube, characterized in that the end ring (6) ※ Note: The disclosure is based on the initial application.
