Yiyang County tailings tailings pipeline transportation manufacturers - commonly tailings pipeline mainly ultra high molecular weight polyethylene pipe, ceramic pipes, made of steel pipe and seamless. But after a long proved uneven thickness of the ceramic layer, the quality of instability. Made of steel pipes poor wear resistance, poor impact resistance. Seamless poor wear resistance. Luoyang, China New material produced tailings pipeline (ultra high molecular weight polyethylene pipe) is 4-7 times of steel, 2.3 times pe tube. Yiyang County tailings tailings delivery pipeline manufacturer - tailings pipeline Process Description: material compounding extruder, molten plastics ---- ---- ---- cuff trim molding ---- Detection --- Finished do the following: 1. Automatic feeding hopper (raw carbon black and paraffin as ultra high molecular weight polyethylene powder) 2, an extruder, output of finished products (machine output pressure of about 190 kg, heating temperature temperatures up to 240 degrees Celsius, a total of five districts) 3, ahead of the mounting flange, ready flange (according to the required size to conduct a truncation error of two centimeters) 4, ahead of the pre-heater is heated by crane put the super senior the heater (1, then use the marker to determine the length of the heating tube of ultra-high, usually around ten centimeters, should be greater than two centimeters long flanging die groove; 2, the temperature of the tube 340 degrees to 350 degrees to achieve the most appropriate general time 40 minutes) 5, while heating the tube should die, while the die with guns (mold is based on ultra-high pipe diameter and decide on the burring machine pretreatment; pretreatment aim is to ensure ultrahigh pipe temperature does not drop) 6, after heating the tube to move to the flanging machine, tighten the screws mold, cover with guns toward the mold, hot to even (this is to ensure that the temperature of the tube, in order to facilitate flanging) 7, the tube After cooling, remove the mold, and then use the micro-roasted, remove with a knife edge 8, flange irregularities with continuous grinding mill dressing until smooth surface Yiyang County tailings tailings delivery pipeline manufacturer - Luoyang State Run the new material production pipeline warranty period is one year free maintenance warranty period!
