Comrise Machine's HDPE Water Supply Pipe Machine leverages over 20 years of extrusion expertise to manufacture pressure-resistant pipes for drinking water systems. Complying with ISO 4427 and DIN 8074 standards, we ensure leak-free, durable pipes for critical infrastructure.
Technical Advantages
High-Pressure Extrusion System
Co-rotating twin screws (34:1 length-to-diameter ratio) uniformly melt HDPE at 180–220°C.
Output: 250–800 kg/h, with density consistency of ±1%.
Precision Calibration Technology
Wall thickness is automatically controlled by an ultrasonic sensor (tolerance of ±0.2 mm).
Energy Optimization
The HDPE Water Supply Pipe Machine utilizes a regenerative AC drive to reduce power consumption by 30%.
An insulated barrel minimizes heat loss, reducing energy costs by 25%.
Quality Assurance
Component Integrity:
Screw/Barrel: Nitrided 38CrMoAl steel (hardness ≥62 HRC).
Electrical System: Siemens/Schneider components, IP67 protection.
Testing Protocol:
72 hours of continuous operation using SDR 11 (PN 12.5) pipe production.
Hydrostatic Pressure Verification: 2.5 times the operating pressure (according to ISO 1167).
Spool Impact Test: -20°C (ASTM D2444).
Product Features
Multi-layer Capability: Optional co-extruded barrier layer.
Quick Die Change: Interchangeable dies for DN 20–630 mm pipes.
Integrated Marking: Laser engraving of batch number, standard compliance, and manufacturer.
Safety Systems: Emergency stop circuit, thermal fuse, and voltage regulator. Material flexibility: Can process both virgin and recycled HDPE.
