Pipe Extrusion Making Machine Two Three Layers PPR Automatic Huge
Sj65 Water Expanding Tube Extruder Line
Introduction:
Two/Three-Layer PPR Automatic Pipe Extrusion Line – SJ65 Water
Expanding Tube Extruder
Our SJ65 Two/Three-Layer PPR Automatic Pipe Extrusion Line is a
high-performance, industrial-grade solution designed for
manufacturing high-quality multi-layer PPR (Polypropylene Random
Copolymer) pipes with precision and efficiency. This advanced
extrusion line is specially engineered for producing large-diameter
water supply pipes using water expansion technology, ensuring
superior strength, durability, and leak-proof performance.
Equipped with automated controls, this extrusion line features
twin-screw extruders for stable material processing, a multi-layer
co-extrusion system for enhanced pipe structure, and a vacuum
calibration & cooling system for dimensional accuracy. The SJ65
model is ideal for producing PPR pipes used in hot/cold water
supply, HVAC systems, and industrial fluid transportation, meeting
international quality standards.
Extrusion line details:
Raw material + additive → mixing → vacuum feeding machine → hopper
dryer → single screw extruder → color code extruder → mould and
calibrator → vacuum forming machine → cooling tank → haul off
machine → cutting machine → stacker
1. The main machine adopts screws specially used for polyolefin.
Equipped with auto vacuum charger and auto constant temperature
dryer hopper, it possesses features of high production, good
plasticization and stable extruding.
2. Die heads of helical type and basket type are perfect for
polyolefin, and can help to produce sound melting pressure, and
improve the plasticization capacity. Meanwhile, stable
material-flow and pressure grade can be guaranteed.
3. Advanced vacuum calibrating method improves the cleanliness and
hardness of surface. Reasonable high-speed sprinkling cooling water
tank guarantees the pipe quality and high speed stable extruding.
4. Caterpiller of the hauling machine adopts anti abrassion alloy
material, which realizes stable traction, wide frequency adjustment
range and long lifespan.
Features
Multi-Layer Co-Extrusion Technology – Produces two or three-layer
PPR pipes with improved pressure resistance and thermal stability.
High Output & Large Diameter Capacity – The SJ65 extruder supports
large-scale production of huge-diameter pipes (up to Ø160mm or
larger).
Water Expansion Process – Ensures smooth inner walls, excellent
roundness, and superior hydraulic performance.
Fully Automated Operation – PLC control system ensures consistent
quality, reduced labor costs, and high production efficiency.
Energy-Efficient & Stable Performance – Advanced screw design and
optimized heating system minimize energy consumption.
Durable & Low Maintenance – Robust construction with high-grade
materials ensures long service life with minimal downtime.
Compliance with International Standards – Meets ISO, DIN, and ASTM
requirements for PPR pipe manufacturing.
Ideal for pipe manufacturers seeking high-speed, precision
extrusion of multi-layer PPR pipes for plumbing, construction, and
industrial applications.
