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.
Claims21
A system for preparing a cross-linked polyethylene a (PEX-a) pipe, the system comprising:
- a heating device comprising a chamber having 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;
- 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.
An assembly for forming piping, comprising:
- a plurality of infrared ovens each configured to provide 360 degree heating, the infrared ovens being water cooled to provide complete circumferential cooling;
- a driven master wheel positioned at a top side of the assembly directly adjacent to and outside of the plurality of infrared ovens;
- a haul-off device downstream in close proximity to the driven master wheel, the haul-off device being positioned along a center point of the assembly to control stretching of the piping;
- and
- a sensor to measure an outer diameter of the piping.
