The workflow of PE pipe equipment

1、Through the mixing system, all kinds of raw materials required for the pipe are mixed evenly by hot mixing, cold mixing and other steps, and then blown into the dry material bin for use. Roots fan will be sucked into the host under the hopper, through a variety of different feeding methods, such as KMD-60 screw using metering feeding, KMD-114 gravity feeding and so on into the extruder. Materials in the extruder through the screw shear and the role of external heat, the average plasticization into the extruder head, the material in the head is given a certain line shape, and further plasticization after leaving the extruder.



2, PE pipe equipment pipe sizing can be used in internal pressure and vacuum sizing two methods. Our company generally adopts the vacuum sizing method. In the head of the initial molding of the pipe first into the spray calibrating box, the pipe through the calibrating set, through the outer wall of the pipe spray calibrating box vacuum, so that the pipe by the internal pressure and close to the calibrating set set of the inner wall of the sleeve, at the same time, the pipe cooled under the action of the spraying water molding.



3, in the spray sizing box completely cooled pipe in the traction machine under the action of uniform speed, under the control of the measurement device, the planetary saw can be cut to a predetermined length of the pipe, and finally after the flaring process, PE pipe equipment to complete the production of the pipe.
