composite pipe

The advanced equipment and technique have created the OBO aluminium plastic pipe of outstanding quality. 1. Introduce MS2000 aluminium plastic pipe production line of UNICOR, which is one of the aluminium plastic pipe production lines of the highest technology level in current situation of the world, introject the latest technology in the field of welding and plastic extruding, and carry out online pressure resistance testing through injecting 0.5Mpa(about 5kg)compressed air. Adopt computer control for whole process on operation, and the product’s quality is automatically inspected, recorded and controlled online in succession, which have ensured the persistent stability of the quality of OBO aluminium plastic pipe. 2. The welding of the aluminium pips adopts the most advanced ultrasonic welding machine to carry out continuous, lengthways, superposed welding. The welding technique can reach the highest security level to ensure the OBO aluminium plastic composite pipe can reach the pressure resistance performance of top class. 3. The PE of internal and external layers and four extruders with two layers of hot melt glues (adopting three extruders on production line generally)extrude at the same time, through high temperature and high pressure, PE and hot melt glues and aluminium pipe become integrated, which has ensure the structures of five layers of OBO aluminium plastic composite pipe are completely composite. 4. Introduce testing and inspecting instruments of whole set from Germany as well as introducing the production line. Carry out the regular long-break strength testing for OBO aluminium plastic composite pipe and inspection of pressure.
