We Have the Most Targeted Solutions to Solve Your Vacuum Tank Pain Points

1. Vacuum Calibration Tank Stable Vacuum Negative Pressure Control | Core Guarantee for Pipe Dimensional Qualification Rate

• • Vacuum Tank Pain Point: Aging plastic pipe vacuum tanks generally suffer from large vacuum pressure fluctuations, leading to oval pipes, out-of-tolerance outer diameters, and uneven wall thickness; pressure control defects in old vacuum sizing tanks are the primary reason customers initiate old extrusion line vacuum tank replacement.
    Blesson Solution
    1.This vacuum calibration tank is equipped with ABB/Inovance variable frequency closed-loop pressure control, with stable negative pressure fluctuation ≤±1.5kPa;
  • 2.The complete machine adopts an integrated water-vapor structure complying with European standards. It integrates vacuum suction pipelines, cooling water circuits and drainage systems as a single unit. Separate partitions are designed for water and air to prevent backflow, equipped with vacuum silencers for noise reduction, drastically lowering pipeline leakage points.
    2.Multi-chamber segmented independent pressure regulation, each section of the vacuum cooling tank can have independently set vacuum parameters;

2. Vacuum Calibration Tank Modular Compatible Retrofit Design | Adapts to Old Extrusion Line Upgrades

• Vacuum Tank Pain Point: Original vacuum sizing tanks on imported old production lines have non-standard dimensions, making it impossible to connect new equipment; retrofits require factory piping modifications with high costs
  Blesson Solution
  1. Vacuum calibration tanks are available in 2m/6m/8m standard modules, supporting standalone purchase and free combination;Supports custom length
• 2. The 2.2-meter vacuum tank can be used independently during the experimental testing phase to conserve materials, or it can be combined with the 10-meter vacuum tank for mass production.
  3. Three-axis three-dimensional adjustable base seamlessly adapts to all European and American old extrusion main machines;

3. Vacuum Calibration Tank Full-Range Gradient Spray Cooling | Increase Production Speed, Optimize Pipe Mechanical Properties

• Vacuum Tank Pain Point: Aging vacuum cooling tanks have a single spray structure with cooling dead zones, resulting in high pipe internal stress and surface pitting, making it difficult to increase production line speed — this is the core demand for customers replacing vacuum sizing tanks.
  Blesson Solution
  1.The entire vacuum calibration tank features detachable spray nozzles arranged in an internal ring for uniform all-around pipe cooling;
  2.Gradient cooling design: weak cooling in the front section to prevent cracking, strong cooling in the middle section for rapid sizing;
  3.Temperature-controlled drain valve maintains water temperature constant at ±1℃;
  4.Optimized nozzle angles significantly improve overall heat exchange efficiency of the plastic pipe vacuum tank.

4. Vacuum Calibration Tank Full SUS304 Stainless Steel Tank Body | Essential Configuration for Old Production Line Retrofits

• Vacuum Tank Pain Point: Carbon steel plastic pipe vacuum tanks are extremely susceptible to corrosion and perforation from cooling water and PVC additives, requiring frequent full-unit replacement. High downtime costs drive customers to inquire about old extrusion line vacuum tank replacement solutions.
  Blesson Solution
  1.Complete vacuum calibration tank chamber and spray piping are integrally seamless welded with SUS304 stainless steel;
  2.800 series large-size vacuum sizing tanks use 5 mm thickened plates, with inner walls polished after full welding;
  3.Resistant to chemical corrosion, not prone to rust in humid operating conditions;
  4.Service life far exceeds old carbon steel vacuum cooling tanks, significantly reducing tank replacement frequency.

5. Vacuum Calibration Tank Multi-Layer Sealing Pressure-Retaining Structure | Solves Common Vacuum Leakage Problems

• Vacuum Tank Pain Point: Old plastic pipe vacuum tanks only have single-layer sealing; after rubber strips age, pressure continuously leaks and scrap rates soar — this is a key optimization item for 30-year pipe machine tank upgrade.
  Blesson Solution
  1.This vacuum calibration tank is equipped with thickened EPDM multi-layer sealing + heavy-duty stainless steel quick-open cover;
  2.Dual water-gas protection reduces vacuum cooling tank chamber leakage probability;
  3.Quick-disassembly structure allows seal replacement without dismantling the entire vacuum sizing tank, reducing maintenance time.

6. Vacuum Calibration Tank Full-Machine Variable Frequency Energy-Saving Pump Set | Core Solution for Long-Term Production Electricity Cost Reduction

• Vacuum Tank Pain Point: Traditional fixed-frequency plastic pipe vacuum tank water pumps and vacuum pumps operate at full load 24h with no speed regulation during idle periods, resulting in high electricity costs. Enterprises generally carry out PVC HDPE PPR pipe vacuum tank replacement energy-saving retrofits.
  Blesson Solution
  1.Vacuum calibration tank vacuum pumps and water circulation pumps both support ABB/Inovance variable frequency drive;
  2.Automatically adjusts power based on production speed and pipe load, with automatic load reduction during idle periods;
  3.30%~60% overall energy savings compared to old fixed-frequency vacuum cooling tanks;
  4.800 extended vacuum sizing tanks are equipped with dual redundant pump sets for more stable large-diameter production operation.

7. Vacuum Calibration Tank with Dual-Stage Filtration Water Circuit & Sectionally Adjustable Support Rollers | Cut Maintenance Downtime & Eliminate Large Pipe Sagging Deformation

• Vacuum Tank Pain Point: Outdated vacuum sizing tanks lack dedicated filtration systems, causing frequent nozzle clogging and unplanned shutdowns. Their simplistic support structures lead to sagging and eccentricity on heavy-walled pipes, resulting in inconsistent wall thickness and out-of-tolerance roundness.
  Blesson Solution
  1. Specially matched pipe supports for different diameters:
• • Above Ø280mm: Half-moon nylon pallets to calibrate pipe roundness
• • Below Ø160mm: Self-adaptive rolling support brackets

2. All vacuum calibration tanks come standard with bypass dual-stage filters to trap sediment and plastic debris in cooling water.

3. Each roller features independent vertical and horizontal adjustment. Multiple rollers share pipe load evenly to keep pipes centered inside the vacuum cooling tank.

Frequently Asked Questions (FAQ)

Q1: Does the equipment meet European safety standards? What is the delivery lead time?
