双波纹管应用广泛，青岛隆昌捷机械有限公司公司根据市场要求，吸收国外同行业先进技术，自主研发成功。整机生产线采用人机界面控制系统。自动化程度高，运行稳定，产量高。高效率挤出机，挤出量大。其中HDPE双壁波纹管为在线扩口特殊设计的共挤模具，双螺旋设计，优质合金钢制造，满足生产需要。成型机采用卧式结构，梭式传动，德国西门子控制系统，密闭水冷却，真空成型，冷却速度快，生产速度高。独创PE双壁波纹管在线双层扩口，及为双层在线扩口而设计的辅机。

The double corrugated pipe application is widespread, the Qingdaochangjie MachineCo.Ltd according to the market requirement, the absorption overseas same profession vanguard technology, researches and develops successfully independently. The complete machine production line uses the man-machine contact surface control system. The automaticity is high, the movement is stable, the output is high. The high efficiency extruding machine, squeezes out the quantity to be big. And the HDPE dog-legged corrugated pipe altogether pushes for the online flaring special design the mold, the double helix design, the high quality alloy steel manufacture, meets the production needs. The shaper uses the horizontal-type structure, the shuttle type transmission, the German Simens control system, the airtight water cooling, the vacuum forming, the cooling rate is quick, the output velocity is high. Originally creates the PE double wall corrugated pipe online double-decked flaring, and auxiliary engine which designs for the double-decked online flaring.

双壁波纹管：双壁波纹管是同时挤出两个同心管，再将波纹管外管熔接在内壁光滑的塑料管上而制成的。具有光滑的内壁和波纹状外壁，质轻而强度高，比普通UPVC管可节省40-60％的原料，主要用作通讯电缆护管、建筑排气管和农用排水管等。

产品特点：
产品结构独特、抗压能力强、内壁光滑、过流量大、具有良好的弯曲性能、可适应土壤的不均匀沉浮，使用寿命长，地埋可使用50年以上。
