Where is the Bulk Calibration Sleeves used in?

Bulk Calibration Sleeves are used in industrial plastic pipe extrusion environments where high-volume, consistent production is required. These sleeves are typically applied in large-scale manufacturing of pipes such as PVC, HDPE, PP, or PPR, especially when uniformity and dimensional accuracy are essential.

Typical Environments for Bulk Calibration Sleeves:

Environment Type                                                                                                                Description

High-Volume Pipe Production Plants                  Used in facilities producing thousands of meters per day of plastic piping—e.g., water supply, drainage, telecom conduit, etc.

Vacuum Calibration Tanks                                   Sleeves are mounted inside vacuum tanks where they help shape and stabilize the pipe using negative pressure and water

                                                                                cooling.

Automated Extrusion Lines                                  Integrated with automated lines requiring minimal downtime and consistent pipe diameter control.

Dust- and Heat-Controlled Settings                     Often installed in clean and temperature-stable factory zones to prevent distortion and material defects.

Corrugated or Structured Wall Pipe Lines           Used when forming complex wall profiles that require robust shaping during initial cooling.

Large-Diameter Pipe Manufacturing                     Applied when extruding pipes with large diameters (e.g., 250mm–1000mm or more) where bulk sleeves with high structural 

                                                                                 strength are necessary.

✅Environmental Conditions Tolerated by Bulk Calibration Sleeves:

· Temperature: Must endure contact with hot, just-extruded plastic (often >180°C).

· Water & Vacuum: Operate continuously under water spray and vacuum suction.

· Mechanical Stress: Handle friction, pipe drag, and thermal expansion cycles.

✅ Why Use a Bulk Calibration Sleeve:

· Supports mass production without frequent changeovers

· Ensures uniform diameter and roundness

· Reduces cooling time and improves throughput

· Compatible with custom pipe sizes and profiles
