Product Description

Product Description 

Introduction to Pipe Coating Line

The Pipe Coating Line is a specialized production line designed to apply a protective or decorative coating layer onto the surface of plastic or metal pipes. By using advanced extrusion and precision coating technology, this line ensures that pipes not only achieve a smooth and attractive surface finish but also gain enhanced durability, corrosion resistance, UV protection, and extended service life.

The production line is highly flexible and can be customized to meet different customer requirements. It is capable of processing a wide range of coating materials, such as PE, PVC, PP, or rubber compounds, and can accommodate pipes of various diameters. The system integrates automatic extrusion, coating dies, cooling units, haul-off machines, and PLC-controlled operation, which guarantees stable performance, consistent coating thickness, and energy-efficient production.

Thanks to its high efficiency and user-friendly design, the Pipe Coating Line is widely applied in water supply and drainage systems, gas distribution pipelines, cable protection conduits, agricultural irrigation, and decorative applications. It provides manufacturers with a reliable solution for producing coated pipes that meet modern construction, infrastructure, and industrial standards.

Specification

Full Production Line View

The complete pipe coating line is in stable operation inside the factory, with a well-organized layout and compact footprint. Clear operation paths and an advanced control system ensure continuous, efficient production and stable output for pipes of various diameters.

Core Extrusion and Coating Process

A close-up of the extruder and coating die. The high-precision die ensures a firm bond between the coating and the base pipe, with uniform thickness and smooth surface. The automatic temperature control system guarantees a stable extrusion and coating process, greatly enhancing product quality.

Finished Pipes and Applications

The finished coated pipes being discharged feature a neat and attractive appearance with clearly visible stripes. The coating layer not only improves corrosion resistance, UV protection, and wear resistance but also enhances identification and decorative effect. These pipes are widely used in water supply, gas distribution, cable protection, and agricultural irrigation.

FAQ

Q1: What kind of pipes can this line produce?
A1: The pipe coating line can be used for plastic pipes (HDPE, PVC, PPR, etc.) as well as metal pipes (such as steel pipes). The coating can be protective (anti-corrosion, UV-resistant, wear-resistant) or decorative (colored surface, stripes).

 
Q2: What coating materials are used in the line?
A2: Common coating materials include PE, PVC, PP, and rubber. We can also add color masterbatch to produce striped pipes for easier identification and decoration.

 
Q3: What is the pipe diameter range supported by this line?
A3: Depending on the model, the line can cover pipes from Φ20 mm up to Φ400 mm. Customized solutions are available for special sizes.

 
Q4: How is the coating quality ensured?
A4: The line adopts precision coating dies, automatic temperature control, and stable haul-off units to guarantee uniform coating thickness and smooth surface. Optional online measuring devices can further enhance quality control.

 
Q5: What is the power requirement and automation level?
A5: Standard configuration is 380V/50Hz/3Phase (customizable to 220V/415V). The line is fully automatic with PLC and touch screen control, making operation simple and reliable.

 
Q6: How is the line packed and shipped?
A6: The equipment is wrapped with plastic film, key parts are packed in strong wooden cases, and all machines are fixed with steel frames inside the container to ensure safe transportation.

 
Q7: What after-sales service do you provide?
A7: We provide one-year warranty, online technical support, and can send engineers overseas for installation and training if required.
