双壁波纹管生产线采用直接挤出成型工艺，生产效率高，质量可靠。由于其优异的管壁结构设计，管材最轻的重量，即管材成本的大幅度降低，大量替代传统的混凝土管和铸铁管。 This production line adopts the technology of direct extrusion molding It has high production efficiency and reliable quality.Because of the excellent structural design of the pipe wall，the pipe has the lightest weight So it can lower the cost of the pipe. 性能特点：Performance and features ●PE生产线主机采用专业设计的高效单螺杆，产量高、挤出稳定，波纹管内外两层分别有两台挤出机独立供料，可实现内外层使用不同颜色和不同原料的生产。PVC生产线主 机采用高效双螺杆挤出机。 ●特殊结构的复合挤出模头，使内外层壁厚均匀，成型稳定。材质采用38CrMoAIA氮化处理。 ●采用计算机控制系统，实现生产的全自动化，运行可靠、稳定。 ●成型机平台可自动开合，易于操作，断电可自动退出，脱离模头。 ●水冷、风冷相结合的强力冷却系统，可保证较高的生产速度。 ●铝合金铸造成型的成型模块，具有极高的精度、强度、耐磨性以及优异的散热效果。 ●先进的在线扩口功能，确保扩1：3的厚度和圆度。 The host machine of PE production line adopts professional designed efficient single screw extruder with high output and stable extrusion The inside and outside layers of the pipe can realize independently feeding through two extruders It can make sure the inside and outside layers can be produced by different colours and raw material The host machine of PVC production line adopts efficienf double—screw extruder. The compound extrusion die head with special construction can make sure the uniform wall thickness and stable molding of the 1nside and outside layers The material quality of the die head adopts 38CrMoAIA. The production line adopts computer．control system，it can realize the full automation of production. The platform of forming machine can open and close automatically If interruption of power supply．it can exit automatically. The strong forced cooling system with the conjunction of water—cooling and air-cooling can make sure higher production speed. The molding module which is casted by aluminium alloy has the advantage of high precision，intensity．abrasive resistance and excellent heat dissipation. Advanced on—line fIaring function can make sure the thickness and roundness of the flaring. 主要技术参数Main technical parameters
