近日,青岛德意利集团公司研制的PP-R管材、钢塑复合管材、大口径铝塑复合管材生产线通过有关专家鉴定。 PP-R管材生产线设计新颖、工艺合理、性能稳定、运行可靠,生产效率高。该生产线率先采用静态混炼器、在线熔体压力检测、共挤标识、螺旋分配成型模具、BM螺杆等先进技术,达到国内领先水平。整机为PLC控制,参数集中测控。该PP-R管在输送冷热水、暖气、地板采暖方面是取代镀锌管的升级换代产品。
Recently, the PP-R pipe, steel-plastic composite pipe, and large-caliber aluminum-plastic composite pipe production line developed by Qingdao Deli Group have passed the appraisal of relevant experts. PP-R pipe production line has novel design, reasonable technology, stable performance, reliable operation and high production efficiency. The production line took the lead in adopting advanced technologies such as static mixers, on-line melt pressure testing, co-extrusion marking, spiral distribution molding dies, and BM screw to reach the leading domestic level. The whole machine is controlled by PLC and the parameters are monitored and controlled. The PP-R pipe is an upgraded product that replaces the galvanized pipe in conveying hot and cold water, heating, and floor heating.
