Yongte's CE-certified PPR pipe production line for hot and cold water is for making PPR pipes—known for smooth inner walls and consistent size. Highly automated, it ensures stable production, uniform pipe quality, 150-200 kg/h output, and >10 m/min speed.
Yongte is a professional manufacturer of hot/cold water PPR pipe production lines—specialized systems for continuous manufacturing of high-quality PPR pipes. These pipes are recognized for smooth inner surfaces and uniform dimensional accuracy.
Polypropylene Random (PPR) pipe has risen to prominence as the preeminent solution across a spectrum of global applications, including the conveyance of potable water, building drainage systems, underfloor heating networks, and various industrial fluid transportation infrastructures. The material's preeminence in the market is underpinned by a suite of inherent advantages: it is non-toxic and odorless, thereby ensuring the safety of water supplies; it endures high temperatures and effectively resists corrosion; and it provides exceptional thermal insulation properties, which enhance energy efficiency. Furthermore, the precision engineering of the machinery, which utilizes cutting-edge, high-efficiency single-screw extrusion technology, ensures a stable and dependable manufacturing process for PPR pipes with outer diameters ranging from 16mm to 63mm. The equipment is distinguished by its high level of automation, which markedly improves production efficiency and ensures the consistent delivery of products that are of superior quality and uniformity.

1. Raw Material Processing System: PE material is mixed with additives, such as color masterbatches, in a mixer. The vacuum feeder automatically sends the mixture to the extruder drying hopper, removing moisture to ≤0.1%—a critical factor for product consistency.
2. PPR Pipe Extruder: Utilizes an SJ65/33 high-efficiency single-screw extruder with a 55KW servo motor, which reduces power consumption by approximately 20%. Features include a direct-drive gearbox for higher efficiency and easier maintenance, a durable 38CrMoALA alloy steel screw barrel that is nitrided for wear and rust resistance, an infrared heating system, and Omron automatic temperature control.
3. Marking Line Extruder: The SJ25 extruder is used to imprint marking lines onto PPR pipes. It can produce either a single marking line or multiple marking lines, depending on the customer's specifications.
4. Specialized PPR Pipe Mold: The mold is equipped with a basket or spiral structure die head to ensure the uniform extrusion of the material.
5. Vacuum Calibration Tank: The tube blank undergoes rapid calibration through vacuum adsorption to guarantee dimensional precision, with a vacuum level ranging from 0.06 to 0.08 MPa. The tank is constructed from stainless steel.
6. Spray Cooling Tank: Equipped with multi-stage spray cooling technology, this tank maintains the water temperature below 20℃ to ensure the rapid and uniform cooling of pipes. Constructed from stainless steel, it offers exceptional corrosion resistance and durability for sustained, stable operation.
7. Pull-off Traction Machine: Draws pipes at a consistent speed of 3-15 m/min for uniform length and stable production. Equipped with precision control systems to maintain consistent tension, preventing deformation and ensuring dimensional accuracy.
8. Planetary Cutter: The cutter enables automatic, fixed-length, chip-free cutting with smooth, burr-free edges, specifically optimized for small to medium diameter PPR pipes. Its precision cutting mechanism ensures consistent length accuracy and minimizes material waste during production.
9. Laser Printing Machine: The machine employs laser technology to display product specifications and batch information in real-time, eliminating the need for consumables.
10. Stacking Rack: Automatically stacks finished pipes neatly, with adjustable height and layer count for different pipe lengths and storage needs. Its sturdy frame and anti-slip design ensure stable stacking and easy handling, boosting post-production storage efficiency.
11. Electric Control System: The system incorporates high-end electrical components, including ABB frequency converters, Siemens contactors, Omron temperature controllers, and Inovance servo controllers.
The 16-63mm PPR pipe, made of random copolymer polypropylene, is an eco-friendly and durable plastic pipe that is easy to install. It has widely replaced traditional galvanized and copper pipes. The pipe's core advantages, including being non-toxic, odorless, resistant to high temperatures and corrosion, and providing excellent thermal insulation, have made it the mainstream choice for global water supply, drainage, heating, and industrial fluid transport.
