**Product Information**
The PVC pipe extrusion line is primarily used for manufacturing plastic pipes for agricultural water supply and sewage, as well as for building industry water supply and sewage systems. It is also suitable for cable and wire installation.
This production line consists of a twin-screw extruder, vacuum tank, cooling tank, haul-off unit, cutter, and storage table. The single extruder and haul-off unit use international brand AC inverter speed control, while the vacuum pump and haul-off motor are equipped with premium brands to ensure stable performance.
The extrusion line can produce pressure water pipes, drainage pipes, industrial pipes, and cable ducts. The screw design is tailored to meet the processing requirements of high-filling materials such as calcium carbonate (CaCO3). By changing molds and auxiliary equipment, it can produce UPVC, CPVC, PVC-M, PVC-O, foam core layer pipes, and spiral hollow wall pipes.
The haul-off unit can be equipped with 2/4/6/8/10/12 belts depending on the pipe size, and the cutter can be either swarfless, saw blade, or planetary cutting type. The system features stable performance and high efficiency. With configuration changes, it can also produce PE, PP inner spiral pipes, hollow pipes, and foaming pipes.
The entire line is fully automated, easy to operate, and delivers reliable performance, reaching international leading standards.
Optimized spiral dies ensure uniform melt distribution, resulting in even pipe walls and improved pressure resistance. The copper vacuum calibration sleeve with a water lubrication ring, combined with a twin-chamber vacuum tank featuring spray cooling and semi-circular nylon support, ensures fast calibration, increased production capacity, and reduced operational costs. These designs are particularly effective for large-diameter pipe production and high-speed operations.
All vacuum tanks and water cooling tanks are made from stainless steel. A dual water supply line with a filtration system, water level and temperature control system, and optimized positioning of bayonet-type spray nozzles further enhance performance.
The twin or multi-caterpillar haul-off unit is equipped with high-quality rubber blocks or belts (for high-speed production), ensuring accurate driving and control, stable speed, and reliable operation.
Accurate non-scraps cutting machines (for pipes less than 160mm) and planetary cutting machines guarantee smooth and uniform cut sections.

An industrial cooling system is a critical facility used in industrial production processes to reduce the temperature of equipment, products, or environments. Its purpose is to protect mechanical equipment from overheating damage, maintain the stability of production processes and product quality, and improve energy efficiency. The design and implementation of such systems range from simple water cooling to complex multi-stage refrigeration solutions, varying according to specific application requirements.
Common types
1. Circulating water cooling system
One of the most basic forms of industrial cooling is to send cold water to the equipment that needs to be cooled through a water pump, absorb heat, and then return it to the cooling tower or heat exchanger for cooling, and then circulate it again.
2. Air cooling system
Using a fan to force air circulation and remove the heat emitted by the device is common in small devices or specific environments.
3. Coolant/Refrigerant System
Using specialized coolant or refrigerant, such as ethylene glycol solution, effectively removes heat with lower freezing point and higher boiling point, suitable for situations requiring wide temperature difference cooling.
4. Refrigeration unit
The complete circulation system including compressor, evaporator, condenser, and expansion valve absorbs heat through the phase change of refrigerant to achieve low-temperature cooling.
Key components
Radiators/heat exchangers: promote heat exchange.
Water pump or fan: drives the circulation of cooling medium.
Controller: Monitor and regulate the cooling process.
Liquid storage tank: stores cooling medium.
Filter: Keep the cooling medium clean to prevent clogging.
The Importance of Industrial Cooling Systems
Improve production efficiency: Keep the machine running within the optimal temperature range, reduce failure rates and downtime.
Extend equipment lifespan: effectively dissipate heat to reduce wear and damage, and lower maintenance costs.
Energy conservation and emission reduction: A well-designed system can significantly reduce energy consumption, in line with sustainable development goals.
Ensuring product quality: In certain processing procedures, such as plastic injection molding, semiconductor production, and food processing, temperature control directly affects the quality of the final product.
Application in various industries
Electric power generation: cooling of generators and transformers.
Petrochemical industry: heat management of refineries and chemical reactors.
Metal processing: cooling of machine tools, laser cutting equipment, and welding equipment.
Electronic manufacturing: Temperature control for server farms and data centers.
Food and beverage: temperature control during fermentation and refrigeration processes.
epilogue
Industrial cooling systems are an indispensable part of modern industrial operations, and their effectiveness directly affects production efficiency, costs, and environmental indicators. With the advancement of technology, future industrial cooling solutions will further develop towards higher energy efficiency, lower environmental impact, and intelligence.
