Abstract
A system for preparing a cross-linked polyethylene a (PEX-a) pipe. The system includes a heating device with a chamber having a central axis, an inlet, and an outlet; oscillating infrared (IR) lamps and a water-cooling apparatus for cooling the temperature in the chamber, and a controller having a program code for regulating oscillation of the IR lamp, an extruder for conveying a cross-linkable feedstock into the chamber, and a pipe head for forming the PEX-a pipe.
IPC Classes ?
- B29C 48/90 - Thermal treatment of the stream of extruded material, e.g. cooling with calibration or sizing, i.e. combined with fixing or setting of the final dimensions of the extruded article
- B29C 48/00 - Extrusion moulding, i.e. expressing the moulding material through a die or nozzle which imparts the desired formApparatus therefor
- B29C 48/09 - Articles with cross-sections having partially or fully enclosed cavities, e.g. pipes or channels
- B29C 48/92 - Measuring, controlling or regulating
- B29K 23/00 - Use of polyalkenes as moulding material
- B29L 23/00 - Tubular articles
- C08F 8/00 - Chemical modification by after-treatment

Abstract
The present disclosure relates to a system for preparing a cross-linked polyethylene a (PEX-a) pipe. The system can include a heating device with a chamber that has a central axis, an inlet, and an outlet. A plurality of oscillating infrared (IR) lamps and a water-cooling apparatus for cooling the temperature in the chamber. The system includes a controller comprising a program code for regulating oscillation of the IR lamp; an extruder for conveying a cross-linkable feedstock into the chamber; and a pipe head for forming the PEX-a pipe.
