NEXA Expansion Line
Developed as a modular system for the continuous expansion of heavy wall tubing in the range of 12 - 225 mm (expanded diameter) with wall-thickness ranging from 2.0 - 6.0 mm. Depending on the size, quality and consistency of the crosslinked tubing, speeds of 3 - 4 m/minute or even higher can be achieved.
The expansion line consists of the following major modules:
- Portal unwinder
- Belt Haul-input module
- Double pressure oil-heating modules
- Expansion and calibration module
- Belt Haul-output module with pinch rollers
- Clamping module
- Cutting module
Features:
- New modular design, state of the art electronics and drives
- Precise longitudinal change control
- Precise temperature control
- Continuous circulation of the heating liquid
- Illuminated view windows for observing the product during the production process and for maintenance
- Pressure control for pressure inside the tubular heating tank and inside the tubing
- All drive elements are made of none-corrosive materials
- Liquid level indicator & Internal/external pressure control
