PVC Pipe Extrusion Machine Line

Do you want to invest  plastic pipe machine ?Are you the first time to production of plastic pipes ? 

Do you have a lot of questions about this? Well today I will give you some detailed knowledge about plastic pipe lines. Hope that helps you.

1. What is a pipe extrusion machine?

A pipe extrusion machine is an industrial manufacturing system used to produce continuous lengths of plastic or PVC pipes with precise diameters and wall thicknesses. It works by melting raw plastic material (such as PVC, HDPE, or PP) and forcing it through a die to form a pipe shape, which is then cooled, calibrated, and cut to the desired length.  

Key Components of a Pipe Extrusion Machine  
1. Extruder – Heats and melts plastic granules using a rotating screw inside a barrel.  
2. Mould – Shapes the molten plastic into a pipe profile.  
3. Vacuum Calibration Tank – Ensures accurate pipe dimensions and smooth surface finish.  
4. Cooling System – Solidifies the pipe using water baths or spray cooling.  
5. Haul-Off & Cutting Unit – Pulls the pipe at a controlled speed and cuts it to length.  
6. Control Panel (PLC/HMI)– Automates the process for consistent quality.  

Types of Pipes Produced  
 PVC Pipes (for plumbing, drainage, electrical conduits)  
HDPE Pipes (for water supply, gas distribution)  
PPR Pipes (for hot/cold water systems)  
Multi-layer Pipes (for enhanced strength & corrosion resistance)  

Why Use a Pipe Extrusion Machine?
-High Production Speed(up to 1,200 kg/h)  
-Precision Sizing (±0.1mm tolerance)  
- Energy-Efficient (servo motors & heat recovery systems)  
- Low Maintenance(robust industrial design)  

PVC pipes are very common in our lives. Let me first give you a detailed introduction to the production and manufacturing process of PVC pipes and their applications in life.

Learn about PVC pipe extrusion machine from 3aspects: application, configuration, and types.

Applications of PVC Pipe Extrusion Machine  

A PVC pipe extrusion machine is used to manufacture a wide range of polyvinyl chloride (PVC) pipes for various industries. Thanks to PVC's durability, chemical resistance, and cost-effectiveness these pipes are essential in:  
 

1. Plumbing & Water Supply Systems 
Drinking Water Pipes – UPVC (unplasticized PVC) pipes are safe for potable water distribution.  
Hot & Cold Water Lines – CPVC (chlorinated PVC) pipes withstand higher temperatures.  
2. Sewage & Drainage Systems 
Underground Drainage Pipes – Smooth inner walls prevent clogging.  
Wastewater & Sewer Pipes – Resistant to chemicals and corrosion.  
3. Electrical & Telecommunications
Electrical Conduits – Flame-retardant PVC protects wiring.  
Fiber Optic Ducts – Lightweight yet crush-resistant for cable protection.  
4. Agriculture & Irrigation 
Drip Irrigation Pipes– UV-stabilized PVC for outdoor use.  
Sprinkler Systems – Lightweight and easy to install.  
5. Industrial Applications
Chemical Transport Pipes – Resistant to acids, alkalis, and oils.  
Compressed Air Lines – High-pressure PVC pipes for factories.  
6. Construction & Infrastructure
Ventilation Ducts – Used in HVAC systems.  
Scaffolding Covers – Temporary protective piping.  
 

Why Choose PVC Pipes?  
Cost-Effective– Cheaper than metal alternatives.  
Lightweight & Easy to Install – Reduces labor costs.  
 Corrosion-Resistant– Long lifespan (50+ years).  
Environmentally Friendly– Recyclable material.  

2.What is the configuration of PVC pipe extrusion machine configuration:

 PVC pipe extrusion machine is actually a series of main machines with optional auxiliary machines. (Pls refer to the table below. )So we also call it the PVC pipe extrusion machine line. 

The most import machine of this produciton line is following :

1. Conical double screw extruder adopts 38CrMoAlA material screw and barrel, nitriding process. It is a special design for PVC powder extrusion. By changing the mould and auxiliary machines, it can produce many products like PVC profile, PVC ceiling, PVC trunk, PVC door, PVC foam board, etc .It can according to customer requirement to choose the PLC contral or normal contral .

2.PVC pipe extrusion mould  is made of 40Cr, which is used to modify and shape the final products.

3 .The vacuum calibration tank body is made of stainless steel. The tank is equipped with a vacuum pump and a water pump. It is used to cool and size the pipe with a vacuum environment. It works together with pipe die parts sizing sleeve to make the PVC pipe into wanted diameter and into a round shape. It can also a little adjust pipe thickness. Its cover material is cast-aluminum.

4.the haul-off machine has many models to choose from according to pipe OD like 2-claws, 3-claws, 4-claws, 6-claws, 8-claws, 10-claws, etc.  This part is used to haul the pipe at the same speed as the extrusion. Sometimes it can have the function to adjust PVC pipe thickness a little. When its speed is higher than extruder, the pipe wall becomes thinner while its speed is lower than extruder, pipe wall becomes thicker. Hauling speed is controlled by ABB inverter.

5. The planetary cutter of the PVC pipe production line is used to cut pipes into wanted length such as 3m, 3.5m length, etc. It is controlled by PLC.  (Want to know how to operate cutter, click planetary cutter)

6.Belling machine also called pipe socket machine is a specialized industrial device used to create a bell-shaped socket (expansion) at one end of PVC pipes, enabling quick and leak-proof connections in pipeline systems. It is widely used in water supply, drainage, irrigation, and cable protection applications.  

Key Features of pvc belling machine :   
1.Heating System: Uses electric heating plates or infrared heaters to soften the pipe end for easy forming.  
2.Molding & Expansion: A hydraulic or pneumatic mechanism pushes a precision mold into the heated pipe end to form the bell shape.  
3.Cooling System: Air or water cooling ensures the expanded end retains its shape.  
4.Automation: Available in manual, semi-automatic, and fully automatic models for high-efficiency production.  

3.What are the types of PVC pipe extrusion machine:

CAMEL MACHINERY as customized PVC pipe production line suppliers, supplying mainly three types of PVC pipe extrusion equipment. They are as below.

1. single cavity pipe produciton line for PVC pipe OD from 16mm to 800mm;
2. two cavity pvc pipe produciton line  for pipe OD from 16-63mm, 50-110mm and 90-160mm:
3. Four cavity PVC pipe extrusion line for pipe OD 16-32mm.
