Recently, the PPR pipe, steel-plastic composite pipe, and large-caliber aluminum-plastic composite pipe production line developed by Qingdao Deli Group have been identified by relevant experts.
Deli Company is mainly engaged in research and development of new plastic building materials production equipment and products. In less than two years since its establishment, it has developed a series of products and obtained a number of national patents. PPR pipe production line has novel design, reasonable process, stable performance, reliable operation and high production efficiency. The screw structure of the extruder, feeding of material and groove of the barrel, and advanced transmission system configuration are advanced. 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 measured and controlled. The PPR pipe is an upgraded product that replaces the galvanized pipe in terms of conveying hot and cold water, heating, and floor heating.
The steel-plastic composite pipe production line has successfully solved the difficult technical problems of difficult bonding between steel and plastics, especially the fusion welding of multiple technologies, and reached the international advanced level. The production line has reasonable design, high degree of automation, high production speed, stable performance and reliable operation. It uses on-line detection such as eddy current testing and laser caliper, online surface treatment of steel strip, and steel-plastic composite special forming technology to effectively ensure the steel pipe. The quality of the product. This kind of steel-plastic composite pipe can be widely used in power systems, oilfields, oil and gas transmission, and Western Development “West-East Gas Transmission†and other construction projects.
Large-diameter (90 series) aluminum-plastic composite pipe production line has a high degree of automation, high production speed, leading domestic level of the whole machine, producing a large-caliber aluminum-plastic pipe with uniform inner wall, good pressure resistance performance, and high peel strength, further enhancing the product's The competitiveness has greatly broadened the market and is one of the major alternatives to the upgrading of galvanized pipes.
