75-125mm PPR Pipe Making Machine

Yongte is a top Chinese manufacturer of plastic pipe extrusion equipment, specializing in R&D, production, and customization of the 75-125mm PPR Pipe Making Machine—a high-precision extrusion line for medium-diameter PPR pipes. These pipes are ideal for drinking water systems, home/commercial sewage, and underground electrical conduits, so the machine is widely used in residential buildings, municipal projects, and large agricultural irrigation systems. Using advanced single-screw extrusion tech with optimized screw design (segmented mixing zones and precise temperature control), this equipment ensures steady production ofPPR pipesfrom 75 to 125mm in diameter. It’s fully automated (from material feeding to cutting), saves 15% more energy than regular models, and makes high-quality pipes (with ±0.1mm size accuracy and 16 bar pressure resistance).

Process Flow

PPR resin + color masterbatch → mixing → vacuum feeding → drying → extruder plasticizing (180-210℃) → mold forming → vacuum calibrating → multi-stage spray cooling → laser printing → pull off traction → fixed-length cutting → finished product stacking

Product Parameter

Core components

1. Material Feeding and Drying:	The PE material is automatically conveyed to the extruder's drying hopper via a vacuum feeder, where moisture is removed to ensure the PE material's moisture content remains below 0.1%, thereby guaranteeing product quality.
2. PPR pipe Extruder:	Equipped with SJ75/33 high-efficiency single-screw extruder, this component integrates 55KW energy-saving servo motor (reducing power consumption by approximately 20%), direct-drive gearbox (ensuring high transmission efficiency and simplified maintenance), wear-resistant and corrosion-resistant screw barrel (forged from 38CrMoALA alloy steel with precision nitriding treatment), efficient infrared heating coil system, and automated temperature control system (featuring Omron’s high-precision temperature controller). These advanced configurations collectively ensure stable material melting, uniform extrusion pressure, and consistent product quality throughout the production process.
3. Marking Line Extruder:	The SJ25 extruder is utilized to create marking lines on PPR pipes. It can produce either a single marking line or multiple marking lines, depending on the customer's requirements.
4. Specialized PPR pipe Mold:	Equipped with basket or spiral structure die head to ensure uniform extrusion of the material.
5. Vacuum Calibration Tank:	The extruded tube blank undergoes rapid precision calibration via vacuum adsorption, ensuring strict dimensional accuracy (vacuum level maintained at 0.06–0.08 MPa). Constructed from food-grade stainless steel, the tank features a multi-zone vacuum control system and efficient water circulation cooling, which collectively guarantee consistent pipe roundness, smooth surface finish, and adherence to tight tolerance standards throughout high-speed production.
6. Spray Cooling Tank:	Equipped with multi-stage spray cooling technology, this tank maintains water temperature below 20°C to ensure rapid and uniform cooling of pipes. Constructed from stainless steel, it offers excellent corrosion resistance and durability for long-term stable operation.
7. Pull-off Traction Machine:	Draws pipes at a steady speed (3-15 m/min) to ensure uniform length and stable production. Equipped with precision control systems, it maintains consistent tension during the traction process, effectively preventing pipe deformation and ensuring dimensional accuracy.
8. Planetary 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:	Displays product specifications and batch information in real-time using laser technology, with no consumables required.
10. Stacking Rack:	Automatically stacks finished pipes in an orderly manner, with adjustable stacking height and layer count to accommodate different pipe lengths and storage requirements. Constructed with a sturdy frame and anti-slip design, it ensures stable stacking and easy handling of finished products, optimizing post-production storage efficiency.
11. Electric control system:	including ABB frequency converters, Siemens contactors, Omron temperature controllers, and Inovance servo controllers.PLC Touch Screen Control System (Optional), Intelligent Temperature Control System, Alarm and Protection System

Product Application

The 75-125mm PPR (random copolymer polypropylene) pipe, an environmentally benign and enduring alternative to traditional galvanized and copper pipes, has extensively supplanted these conventional options. Its intrinsic benefits, such as a non-toxic and odorless composition, resistance to high temperatures, corrosion, and superior thermal insulation characteristics, have established it as the preeminent selection across the globe for applications in water supply, drainage, heating systems, and the conveyance of industrial fluids.

Yongte Machine Advantages - humanized mechanical design and durable quality

After years of innovation and quality focus, we use high-strength, wear-resistant materials for our plastic pipe machinery. These machines undergo precision forging and rigorous quality tests to withstand high-frequency use wear and harsh environment erosion.
