Description:

This PVC pipe production line is an automated complete set of equipment that integrates mixing, extrusion, shaping, cooling, traction, cutting, and flipping. It is designed for efficient and high-precision production of hard PVC pipes (such as water supply pipes, drainage pipes, threading pipes, power protective sleeves, etc.), and is suitable for large-scale manufacturing of multi specification pipes ranging from φ 110mm to φ 400mm.

Based on more than 20 years of experience in extrusion equipment research and development, the core components of the production line are customized high torque screws and barrels, combined with an intelligent temperature control system, which can achieve uniform plasticization and stable extrusion of PVC materials, effectively avoiding material degradation and uneven plasticization problems, and ensuring that the wall thickness of pipes is controlled within ± 0.3mm.

The production line is equipped with a combination device of vacuum sizing box and spray cooling tank, which ensures high roundness and smooth surface without defects of the pipes through precise vacuum adsorption and segmented cooling; The servo traction system runs smoothly, with adjustable traction force and precise matching with extrusion speed to prevent pipe stretching and deformation; The fully automatic cutting saw adopts CNC positioning, with a flat cutting end face and a length error of less than ± 1mm, meeting the accuracy requirements for mass production.

The entire line adopts a PLC human-machine interface control system, which can display production parameters (temperature, speed, output, etc.) in real time, support parameter storage and one click calling, and is easy to operate; Simultaneously equipped with fault warning and shutdown protection functions, reducing manual intervention costs and improving production safety.

This production line is compatible with the processing needs of PVC powder and granular materials, with a production efficiency increase of 20% -30% compared to traditional equipment, and energy consumption reduction of more than 15%. The performance indicators of the finished pipes meet the requirements of the national standard GB/T 5836 and international standards, and are widely used in the fields of building water supply and drainage, municipal engineering, electrical wiring, etc. The equipment is exported to many countries around the world and widely recognized by customers.

High torque screw plasticization technology for more stable material handling

Customized alloy screw and barrel, designed with a gradient pitch and barrier structure, combined with an intelligent multi-stage temperature control system, can achieve uniform melting and plasticization of PVC powder/granules, effectively solving the pain point of PVC thermal sensitivity and easy degradation. The screw torque is increased by 30%, the extrusion pressure fluctuation is controlled within ± 2%, ensuring that the wall thickness tolerance of the pipe is stable at ± 0.3mm, and the mechanical properties of the finished product are highly consistent.

Vacuum sizing + segmented cooling technology for superior forming accuracy

Adopting a closed-loop vacuum sizing box with real-time adjustable vacuum degree, combined with high-pressure spray segmented cooling tanks, to achieve "progressive shaping cooling" of the pipe after extrusion from the die. The roundness error of the pipe is less than 0.5%, and the surface is smooth without any bumps or ripples, completely avoiding the deformation and diameter reduction problems caused by traditional cooling methods. It can accurately produce full specification pipes from 16mm to 800mm.

Servo linkage traction cutting technology, with more outstanding production efficiency

The servo traction system is precisely linked with the extrusion host, with infinitely adjustable traction force and a speed synchronization error of less than 1%, to prevent pipe stretching and deformation; The fully automatic CNC cutting saw is equipped with a laser positioning device, and the cutting end face is flat and free of burrs, with a length error of less than ± 1mm. It supports continuous unmanned operation and increases production efficiency by 20% -30% compared to traditional equipment.

PLC intelligent control system, more convenient operation and maintenance

The entire line is equipped with a human-machine interface PLC control system, which can monitor key parameters such as temperature, pressure, speed, and output in real time. It supports the storage and one click call of more than 100 production formulas, and does not require repeated debugging when changing pipe specifications. Built in fault self diagnosis and warning protection function reduces equipment failure rate by 40%, significantly reducing manual intervention costs and downtime.

Energy saving and consumption reducing design, more economical overall cost

Adopting frequency conversion energy-saving motor and insulation barrel design, energy consumption is reduced by more than 15% compared to traditional equipment; The core components are made of wear-resistant alloy material, and the service life of the screw barrel is extended to over 8000 hours, with a maintenance cycle extended by 50%; Simultaneously compatible with the production of recycled PVC materials, with a maximum addition ratio of up to 30%, further reducing raw material costs.

In addition, the production line complies with the national standard GB/T 5836 and the EU CE standard, and the finished pipes can directly meet the strict requirements of building water supply and drainage, municipal engineering and other fields.

Applications:

PVC pipe production lines are specialized automated equipment designed for manufacturing PVC pipes of different specifications, hardness levels, and functions. Leveraging high-precision molding and intelligent control technologies, their applications span multiple fields driven by the excellent performance of PVC pipes—such as corrosion resistance, low cost, light weight, and easy installation.

1. Building & Construction Industry

This is the most mainstream application field of PVC pipes.

• Water supply & drainage systems: The production line manufactures rigid PVC (u-PVC) water supply pipes and drainage pipes, which are widely used in residential buildings, commercial complexes, and industrial plants. These pipes resist rust and scaling, ensuring clean water delivery and smooth wastewater discharge.
• Electrical threading pipes: Produces thin-walled PVC threading pipes for hiding wires and cables in building walls, floors, and ceilings. The pipes have good insulation performance, protecting circuits from external damage and reducing fire risks.
• Ventilation ducts: Manufactures PVC ventilation pipes for indoor ventilation systems in kitchens, bathrooms, and factories, with advantages of moisture resistance and easy cleaning.

2. Municipal Engineering

• Urban drainage & sewage treatment: Large-caliber PVC pipes produced by the line are used in municipal drainage networks, responsible for collecting rainwater and discharging domestic sewage. Their corrosion resistance adapts to complex underground environments and has a long service life.
• Underground cable protection pipes: PVC power/cable protection pipes are laid underground to protect high-voltage cables, communication optical cables, etc., preventing cable damage caused by soil corrosion, construction excavation, and animal gnawing.

3. Agricultural Field

• Irrigation systems: Produces PVC agricultural irrigation pipes for drip irrigation, sprinkler irrigation, and flood irrigation systems in farmlands, greenhouses, and orchards. These pipes are lightweight, easy to lay and assemble, and can withstand certain water pressure, improving water utilization efficiency.
• Livestock breeding facilities: Used to make drinking water pipes and sewage discharge pipes for livestock farms, with characteristics of easy cleaning and corrosion resistance to animal excreta.

4. Industrial Applications

• Chemical fluid transportation: For transporting non-strong acid and alkali chemical media in chemical plants, pharmaceuticals, and food processing industries, PVC pipes have stable chemical properties and avoid medium contamination.
• Industrial wastewater discharge: Handles the discharge of general industrial wastewater, reducing the cost of pipe maintenance and replacement compared with metal pipes.
