The 6-Meter Vacuum Tank — a Key Link in Stable Pipe Calibration on KingJoy Lines
November 10, 2026
In a plastic pipe extrusion line, the vacuum sizing tank handles the core tasks of pipe calibration and cooling, directly determining the pipe's dimensional accuracy and roundness. KingJoy's 6-meter vacuum sizing tank — with its extended tank body, multi-stage vacuum control and water-film cooling design — provides reliable support for stable production of large-diameter pipes.
Core Features
- 6-meter extended tank body: Provides a longer cooling and calibration stroke for large-diameter, thick-wall pipes, ensuring more thorough cooling and more stable dimensions.
- Multi-stage vacuum control: Adjustable vacuum zones keep the pipe closely fitted to the sizing sleeve, effectively ensuring outer diameter accuracy and roundness.
- High-efficiency cooling system: Spray and water-film lubrication cooling deliver uniform heat exchange and adapt to the characteristics of PE, PVC and other materials.
- Stainless steel tank body: Rust-proof and corrosion-resistant, ensuring stable long-term operation and a long service life.
- Sealing and observation design: Front and rear sealing structures reduce water leakage, while observation windows allow real-time monitoring of pipe running status.
- Synchronized operation: Can be speed-linked with the extruder and haul-off unit for coordinated, stable line operation.
Applications
Suitable for PE, PVC and other plastic pipe production lines, especially for the calibration and cooling of large-diameter, thick-wall pipes. Custom configurations are available according to line setup and customer process requirements.
