Vacuum Tanks for Plastic Pipe Extrusion Lines
Designed for flawless performance under the toughest production conditions
With advanced European technology and years of expertise in extrusion equipment design, EXTRUTEX Austria has become one of the leading producers of high-quality vacuum tanks. Our products are trusted not only in domestic markets but also internationally across various industries.
Application of Vacuum Tanks in Extrusion Lines
Vacuum tanks are one of the most critical components of plastic pipe extrusion lines (PE, PP, PVC, PPR, PERT, and others). Their primary function is to create negative pressure (vacuum) at the initial stage when the pipe exits the die head, ensuring that the pipe is precisely shaped and stabilized while undergoing initial cooling.
Technical Features & Advantages
✅ Anti-corrosion stainless steel construction
All tank bodies and water-contacting parts are manufactured from SS304 or SS316 stainless steel, ensuring resistance against moisture, heat, and chemicals. This guarantees long service life and stable performance in harsh industrial environments.
✅ Advanced vacuum control
High-quality vacuum pumps (European or customized) are paired with digital sensors. PLC or industrial automation systems allow precise vacuum pressure adjustment, emergency stop, and live monitoring.
✅ Modular & customizable design
Available in various lengths and configurations – single-chamber, double-chamber, and multi-chamber – ensuring the right setup for different pipe sizes, extrusion speeds, and material types.
✅ Integrated cooling system
Internal spray nozzles distribute cooling water evenly over the pipe surface, ensuring simultaneous cooling and geometric stability.
✅ Reinforced chassis with adjustable supports
The frame is made from heavy-duty steel with epoxy coating, resistant to humidity and corrosion. Adjustable legs and optional wheels simplify transportation and installation.
Reliable Operation Under Variable Conditions
Considering that vacuum tanks operate under demanding environmental conditions (temperature, pressure, humidity), all mechanical, electronic, and hydraulic parts undergo strict quality control testing:
Operating temperature range: -10°C to +50°C
Vacuum pressure tolerance: up to -0.095 MPa
Resistant to thermal shocks and mechanical vibrations
