Calibration Sleeves
Calibration sleeves are using to fix the pipes diameter and becomes one important part of the pipe extrusion lines. Harden is providing 5 types calibration sleeves, which covers nearly all types of plastic pipe extrusion.
● Style I: Calibrating Sleeves for PVC Pipe
1. Special design according to the thermoplastic properties of PVC;
2. Dry inlet avoids the contact between pipe and water, which ensure the quality of the surface;
3. Being made of special copper alloy with excellent properties of hard wearing and heat rejecting, guarantee the maximum lifespan;
4. Different cooling tanks to make excellent intensive cooling according to different pipe dimensions and outputs
● Style II: Adjustable Water Ring Calibrating Sleeves for PE
1. Structure designed specially according to the thermoplastic property of PE;
2. For high haul-off speeds and high viscous materials;
3. Adjustable water ring is posioned to wet pipe surface;
4. Being made of special copper alloy to guarantee the maximum lifespan;
5. For different pipe dimension and output using different cooling tanks to obtain the best results of intensive cooling
● Style IV: Adjustable Water Ring Calibrating Sleeves for PE
1. Super cooling calibrating sleeves suitable for high haul-off speeds and sticking materials;
2. Rapid shaping very little contact between pipe and discs, installed in a pre-cooling chamber;
3. Adjustable spray ring is posioned separately before the inlet helping to wet the pipe surface;
4. The best cooperation with dual pipe dies to produce small diameter and thin-walled pipe
● Style V: Adjustable Water Ring Calibrating Sleeves for PP
1. Special design according to the thermoplastic property of PP;
2. Adjustable water ring is posioned to wet pipe surface, for high haul-off speed and sticking pipes;
3. Made of special copper alloy to guarantee the maximum lifespan;
4. The Different cooling tanks to make excellent intensive cooling according to different pipe dimensions and outputs
● Style VI: Dry Inlet Pipe Calibrating Sleeves for PE
1. Designed for big or middle pipe dimension according to the thermoplastic property of PE;
2. Dry inlet for low haul-off speed, avoiding the contact between pipe and water, which ensure the quality of the surface;
3. Made of special copper alloy with excellent properties of hard wearing and heat rejecting, guarantee the maximum lifespan
