PERT/PEX underfloor heating pipe extrusion line with precision extrusion, calibration, cooling, enclosed traction and double-station coiling.
PERT/PEX Underfloor Heating Pipe Extrusion Line
The PERT/PEX Underfloor Heating Pipe Extrusion Line is configured for flexible heating pipe supplied in coils for radiant floor-heating and low-temperature hot-water systems.
The pictured equipment combines a single screw extruder, dedicated pipe die, vacuum calibration, staged water cooling, enclosed belt traction and double-station winding for stable continuous production.
PE-RT is processed as a thermoplastic. PEX production must be configured around the specified crosslinking route and certified compound; for example, PEX-b normally requires a controlled post-crosslinking stage after extrusion.
Applications
Technical Features
- Continuous small-diameter heating-pipe production
- Stable vacuum sizing and staged cooling
- Enclosed traction for consistent line speed
- Double-station coiling for continuous collection
- Single-layer and project-specific barrier-layer options
Optional Equipment
How to Choose
- Confirm PE-RT or the required PEX crosslinking method and provide the approved material grade.
- Define pipe OD, wall thickness, dimensional tolerance and applicable pressure or heating-pipe standard.
- Confirm single-layer, color-stripe or oxygen-barrier layer structure.
- Provide target output, line speed, coil length, coil dimensions and packaging method.
- For PEX, define the required crosslinking degree, verification method and post-treatment route.
Main Equipment and Process
Core units are configured according to pipe material, diameter, layer structure, output target and downstream collection method.
Single Screw Extruder
The extruder plasticizes the selected PE-RT or compatible PEX compound under a material-specific temperature and screw-speed profile. The screw, drive and feeding system are selected from the required output and compound supplier guidance.
PERT/PEX Pipe Die Head
The dedicated annular die forms the required pipe OD, ID and wall thickness. Tooling is configured for the material, pressure class and any color-stripe or barrier-layer structure.
Vacuum Calibration Tank
Initial vacuum sizing establishes outside diameter and roundness while controlled water circulation removes the first stage of process heat.
Spray Cooling Tank
The downstream cooling section continues controlled heat removal so the flexible pipe reaches a stable temperature before traction and winding.
Enclosed Belt Haul-off
Synchronized belts provide steady traction without damaging the pipe surface. Haul-off speed is coordinated with melt output to control wall thickness and dimensional stability.
Double-Station Pipe Coiler
The finished pipe is measured and collected on a double-station coiler. Coil dimensions and length control are configured for the required delivery and packaging format.
PERT/PEX Underfloor Heating Pipe Line Selection
| Selection item | Available basis | Information to confirm |
|---|---|---|
| Material route | PE-RT or project-specific PEX compound | Provide the approved resin grade and PEX crosslinking method when applicable. |
| Pipe construction | Single layer, stripe or barrier-layer option | Define every layer material and thickness ratio. |
| Pipe dimensions | Project-specific heating-pipe sizes | Provide OD, wall thickness, tolerance and applicable standard. |
| Production target | Project-based output and line speed | Match extruder, cooling length, haul-off and coiler capacity. |
| Finished coil | Configurable coil length and dimensions | Confirm coil ID, OD, width, length and packaging method. |
FAQ
Can one standard machine process both PE-RT and every type of PEX?
No universal configuration should be assumed. PE-RT is thermoplastic, while PEX-a, PEX-b and PEX-c use different crosslinking routes. The approved compound, crosslinking method and product standard must be confirmed before the equipment scope is selected.
Can the line produce oxygen-barrier underfloor heating pipe?
A barrier-layer co-extrusion system can be engineered when the layer materials, adhesive system, thickness ratios and qualification standard are provided.
What information is required for a quotation?
Please provide the material grade, pipe OD and wall thickness, layer structure, target output, applicable standard, crosslinking route for PEX, finished coil dimensions, voltage and plant water conditions.
