Product Introduction
The PPR pipe production line is a complete system designed for manufacturing high-quality polypropylene random copolymer (PPR) pipes. It automates the processes of extrusion, shaping, cooling, hauling, cutting, and socket forming. The line produces durable, corrosion-resistant pipes, ideal for hot and cold water supply systems in residential and commercial buildings, ensuring consistent performance and long service life.
Product Advantage
High-Precision, Stable Extrusion System
Our line is equipped with a high-efficiency single-screw extruder, specifically designed for processing PPR material. It features precision temperature control zones and a unique screw design that ensures uniform plasticization and stable melt pressure. This results in pipes with consistent wall thickness, with tolerances as tight as ±0.1mm, essential for pressure-rated plumbing systems.
Advanced Vacuum Sizing and Multi-Stage Cooling
The line incorporates a multi-chamber vacuum calibration tank and a cascading cooling system. This setup guarantees perfect pipe roundness, smooth internal/external surfaces, and eliminates internal stress. Efficient cooling increases line speed by up to 15%, supporting production rates of 4-8 meters per minute for standard diameters (20mm-110mm).
Fully Automated Control & Cutting Integration
A centralized PLC with a touch-screen HMI allows for precise control and recipe storage. The integrated servo-driven haul-off and orbital cutting system enables fully automatic production, with cutting length accuracy maintained within ±0.5mm. This automation ensures high repeatability and reduces manual intervention.
Integrated Online Socket Forming Unit
A key feature is the integrated hot-forming socket machine. It seamlessly forms consistent, standardized socket ends directly on the production line, achieving a perfect fit for reliable thermal fusion jointing. Socket depth and bead dimensions comply with ISO 15874 standards, ensuring leak-proof connections.

Product Uses
1. Residential & Commercial Hot/Cold Water Plumbing
PPR pipes are the standard choice for indoor water supply systems in houses, apartments, and office buildings. Their excellent thermal resistance ensures safe, durable transport of both hot water (up to 70°C) and cold water with minimal scaling or corrosion.
2. Central Heating & Radiator Systems
Ideal for hot water circulation in underfloor heating and wall-mounted radiator networks. PPR's low thermal conductivity reduces heat loss, while its high-temperature tolerance (short-term 95°C) maintains system stability and energy efficiency.
3. Industrial Fluid Transport & Compressed Air Lines
Used in factories to convey non-corrosive industrial water, chemicals, and compressed air. The pipes' smooth interior prevents buildup, and their resistance to many chemicals ensures long service life in light industrial environments.
4. Solar Water Heating & Renewable Energy Systems
Commonly applied in solar thermal installations for transferring heat transfer fluids. PPR withstands prolonged exposure to heated glycol mixtures and UV exposure (when properly insulated), supporting sustainable energy infrastructure.
