Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0011] Such as figure 1 As shown, the plastic-reinforced spiral pipe without bonding seam includes a plastic-reinforced pipe body 11, an inner smooth surface 12 formed integrally with the inner wall of the plastic-reinforced pipe body 11, and an integrated outer wall of the plastic-reinforced pipe body 11. The formed outer smooth surface 13 and the outer wall of the plastic rib tube body 11 are provided with spiral plastic ribs 14 wound on the tube body.
[0012] The production process of the plastic-reinforced spiral pipe without adhesive joints includes the following steps. The plastic-reinforced pipe material is extruded from the extruder head, and the plastic-reinforced pipe body 11 is formed in the plastic-reinforced pipe forming channel. At the same time, the spiral plastic-reinforced material After entering from the helical material injection ch...
