Kabra Extrusion Enhances PVC Pipe Manufacturing Solutions

Plastic pipes play an indispensable role in modern agricultural irrigation, building water supply and drainage systems, and municipal engineering projects. However, producing high-quality PVC (polyvinyl chloride) pipes efficiently and consistently remains a significant challenge for manufacturers. Kabra ExtrusionTechnik (KET), with decades of expertise in extrusion technology, offers comprehensive solutions for PVC pipe production.

KET specializes in providing complete extrusion production lines, focusing on optimally matched components, advanced automation concepts, and customized solutions. These elements work synergistically to ensure customers can consistently produce high-quality end products.

The twin-screw extruder serves as the core equipment for efficiently producing premium PVC pipes. KET's twin-screw extruders feature screw diameters ranging from 52mm to 168mm and production capacities from 120kg to 2000kg per hour, catering to various production scales. These extruders find applications across multiple sectors including agriculture, water supply, drilling, and riser systems.

Beyond PVC pipes, KET provides specialized solutions for CPVC (chlorinated polyvinyl chloride) pipe production. CPVC pipes offer superior heat and corrosion resistance, making them ideal for transporting hot water and corrosive chemicals. KET's CPVC extruders feature screw diameters from 72mm to 110mm with production capacities between 200kg and 400kg per hour.

• Single/Dual Die Systems: Optional configurations to enhance production flexibility.
• Robust Construction: Specifically engineered for CPVC processing with enhanced wear and corrosion resistance.
• Globally Validated Technology: Incorporates proven solutions with worldwide market acceptance.
• Reduced Burn Frequency: Minimizes material degradation and waste generation.
• Special Screw Geometry: Processes materials with optimal shear force to preserve properties.
• Precision Temperature Control: Utilizes thermal oil circulation for precise screw and barrel temperature management.

KET's foam pipe extrusion systems employ a dual-extruder configuration, with the primary unit producing the foamed core layer and the secondary unit forming the inner/outer skin layers. This setup allows precise adjustment of skin-to-core thickness ratios. The system includes specialized compounding and horizontal feeding devices for foaming agent incorporation.

• Reduced overall density for material savings
• Lower per-unit production costs
• Higher production efficiency compared to solid pipes
• Improved thermal insulation properties

KET's joint venture with Extron Mecanor produces advanced belling equipment that complements its pipe production lines. The innovative pipe handling system enables dual-channel extrusion using a single belling unit, optimizing floor space utilization.

• High-speed operation for increased throughput
• Compact footprint for space efficiency
• Exceptional reliability with minimal maintenance requirements
• Integrated online pipe weighing for quality control
• Advanced belling tool technology for superior finish
